Interested in an angle sawmill. Timing?

I want to order a machine with certain parameters.

To cut off the desired part wooden board or to make a product of the desired thickness, special units will be required. In order to cut, you need circular saws. With their help, you can quickly cut off the desired piece from a board or log. To calibrate the product, you will need a thicknessing machine. Thanks to him, you can make a wooden part required thickness with precision down to the millimeter.

Circular saws are different. Now manual and stationary units are being produced, designed to work with various types of wood products. This equipment is a powerful electric tool, the main part of which is a durable disc with very sharp teeth. Such a unit will easily cut boards, laminate, slats, wood boards. It is even suitable for metal cutting.

Circular saws are different models. Therefore, their specifications may differ. To choose a power tool that is really necessary for production, you should familiarize yourself with the following characteristics of the equipment when buying:

• cutting depth.

  One of the most important indicators of the unit. It depends on the diameter of the disk. The larger its size, the deeper the cut will be;

• engine power is also an important indicator. It affects the speed of the equipment. How more powerful unit, the more productive it will be. Circular saws used in factories can have a power of 2500 watts. This is a very high figure;
• equipment safety. Since circular saws will be constantly used by workers in a woodworking enterprise, they must be completely safe to use. Therefore, you need to choose units with a protection system, a blocker that prevents them from being accidentally turned on.

To calibrate wood blanks, a thicknesser is required. Most often it is used on furniture production because home furnishings manufacturers require professional equipment that would allow them to produce neat and beautiful products. When choosing a thicknessing machine, you need to pay attention to its technical capabilities:

• how often the shaft rotates. The faster it starts to rotate, the more even the surface of the workpiece will turn out;
• the depth and width of the cut, which makes the thicknesser machine. Depth is a measure of how much wood a unit can cut in one pass.
• Width - how wide the machine can handle.

What is a round log and what is it used for?

It is customary to call rounded such a log, from which they cut off on a special woodworking machine upper layer wood. As a result of such processing, the diameter along the entire length of the log will be the same, i.e., a cylinder is obtained from a cone-shaped tree trunk.

Houses made of rounded logs look not only beautiful, but elegant. They are warm, durable, and, most importantly, environmentally friendly. Ordering a house made of logs on the site http://stroi-terem.ru/category/houses-from-rounded-logs/ will not cause any difficulties. By going to the site you can find out prices, terms of work, the possibility of delivery and much more. others

Logs are made in accordance with GOST 9463-88.

The nominal length of such logs should be from 3.5 to 6.5 m in increments of 250 mm. Thus, a total of 13 sizes are possible. Deviation from the obtained length is allowed from + 30 to + 100 mm.

For construction, rounded logs with a certain diameter are usually used. The standard defines the smallest log diameter as 140 mm. Most manufacturers set this diameter from the specified size in steps of 20 mm. Usually the row ends with 280 or 300 mm logs.

But since only for some manufacturers the state standard is a mandatory document, both the length of the logs and their diameter, at the request of the customer, can be made any that will correspond to the design dimensions of the future building.

For laying a rounded log in a log house, a longitudinal groove is cut on one side of it, called a laying groove. Its width should be greater than the radius of the log and match the shape of the lower log as closely as possible. Those. the radius of this groove should be equal to the radius of the log.

Usually, rounded logs are made from "raw" wood and dried to the required condition already as part of a log house. Very often, the drying process is uneven - when the inner layers remain wet, and the outer layers dry quickly. Stresses arise in them, which cause longitudinal cracking of the logs. In the zone longitudinal groove stresses are removed by sampling the laying groove. And on the side of the log opposite from the groove, the stress is removed by a longitudinal cut a few millimeters wide and about 0.05 - 0.1 of the log diameter deep. It is called an unloading or compensation groove.

How are log rounding machines arranged?

Such a machine can be of a positional or through-type type. In the first case, the axis of rotation of the log is fixed, and the log rotates at a frequency of 20 to 60 rpm. Steel roughing and finishing cutters move along the log with a rotation speed of 3,000 - 4,000 rpm. Roughing consists in the fact that first a layer of bark and wood is removed to obtain a given diameter with an allowance for finishing. Then, a thin layer of wood is cut off with a high-speed finishing cutter, and a finished surface is obtained.

In passing machines, the processed log is fed by toothed rollers into a fixed rounding rotor, from which it exits fully processed with compensation and stacking grooves.

• Positional type machines are divided into turning and rotary-cylindrical.
• Lathe-cylindrical is a large lathe with a wooden blank length of up to 7 meters or more and a raw log diameter of up to 500 mm or more. The cylindering rotor contains a rotating cutter, which performs cylindering on the forward pass, and on the reverse pass, laying and compensation grooves are cut.

Theoretically, a simplified model of such a machine can be made at home, but it will be quite dangerous to work on it. A large mass of a rotating log, high speeds of the processing cutter and sufficiently large energy capacities are almost unrealistic for execution in a garage or shed of a private house.

It is easier and cheaper to buy a batch of finished logs and build a house or a bathhouse out of them.

Rounding machine used for wood processing - cylindering, sampling of grooves and a bowl of crown logs, milling a plane. The use of equipment allows you to assemble a log house without additional processing of parts. Operations are carried out for one setting of the workpiece.

Design features of the machine

The operation of the equipment is similar to semi-automatic lathes equipped with a milling head. Automation is provided within a cycle - one approach, during the implementation of which the equipment performs an operation according to the specified parameters. To change actions and control cutting tool operator involvement is required.

The design of the machine has the following components:

• Supports and railroad track.
• Equipment rails - lifting and moving mechanisms.
• Drive and supply of the cutting tool.
• Front and rear headstock.
• Racks and strings for electrical cables.
• Button post.

The working tool is finishing and spherical milling cutters. The equipment uses finishing cutters of 2 sizes of diameters:

• 150 mm. The size of the product at the outlet is 160-190 mm.
• 190 mm. Achievable size - 200-240 mm.

The cutting surface of the finishing cutter lies in the same plane.

By setting the knives of the spherical cutter, the size of the groove is set. The operation of the equipment is provided by asynchronous motors, one of which (front) is responsible for feeding the cutter, the second (rear) ensures the rotation of the workpiece.

The operating parameters for wood processing depend on the type of rock, the state of moisture and freezing of the material, and the thickness of the workpiece. The speed of rotation of the log and the feed of the cutter are subject to adjustment.

The principle of operation of the equipment

Processing of wood blanks is carried out by moving the drive and feeding the finishing or spherical cutters along the log installed on the rail track. The cutting element is fed manually. A finishing cutter is used for longitudinal excavation of material, the spherical shape of the tool is used for milling crown cups.

The wood blank is given rotation or rigid fixed fixation. The position depends on the type of operation. Static fixation is used for cup selections and compensation cuts. Rotational movements are given to the log only when the workpiece is cylindered simultaneously with rigid fasteners.

The mechanism of action of the machine is built on:

• rotational or stationary state of the log blank;
• translational and rotational movement of the cutter.

During cylindering, the accuracy of the given size is achieved, the curvature of the product is eliminated. The processing of the workpiece is carried out according to the axis of the product, taking into account the following features:

• The workpiece is installed with a butt (thickened part) to the headstock to prevent extreme layer removal.
• The translational movements of the cutter are carried out in the direction from the front to the tailstock.

The accuracy of the log cylindering is ensured by rigid fixation of the head and tailstocks and the coaxiality of the fasteners. Obtaining the required product size is achieved in several approaches.

Cylinder operation

In the cylindering operations, a constant rotation of the workpiece is set, fixed in the centers of the stocks, and the cutter is moved along the length of the log. The workpiece is located on the lever lifts from the front to the tailstock. Before starting work, the rail is brought to the headstock.

In the course of work, the following operations are performed:

• supply close workpiece to the headstock;
• installation of the workpiece in the centers of the headstock and tailstock in the form of a rigid fastener by adjusting the screws of the rear latch;
• parameter task milling head for rough minimum material removal;
• sequential start-up of drives for rotation of the workpiece and cutter;
• manual movement of the cutter with a rail;

At the end of the pass, the rotation of the workpiece (drive) stops to bring the rail to its original position and set new cut parameters. Operations are resumed in the same order.

Mounting groove removal operation

Mounting groove - a longitudinal recess on the workpiece, which simplifies the pairing of logs when installing finished products. The difference between the operation of grooving and cylindering is the processing of the workpiece in a fixed position. Sampling operations are carried out in the following order:

• retracting the rail to the position of the headstock;
• installation of a log in the centers of headstock with fixation from rotation;
• adjustment of the horizontal position of the cutter to the processed surface of the log;
• the task of the cutter parameters in a size smaller than the diameter of the workpiece;
• turning on the cutter drive;
• sampling by manual translational movement of the moving cutter with the help of the rack handle.

The parameters of the groove (depth, width) after excavation are unchanged throughout the entire length of the log.

The operation of sampling crown cups

The presence of crown cups facilitates the installation of the structure. Their creation is carried out after cylindering and grooving. Milling cups requires the following sequence:

• fixing the workpiece on the rails using the brake;
• drawing a graphic mark of the cup;
• alignment of the center of the cutter and the planned excavation;
• turning on the drive of the working tool;
• directly excavation of the material by moving the cutter by the handle down.

Before carrying out the excavation, the task of flying out the cutter knives set to a single radius is required. In the process of working with spherical cutters, the positions of the knives are checked at least 2 times per shift and before the start of operation of the equipment.

Installation of equipment

The reliability and productivity of the machine is ensured by a technically competent installation. Installation of equipment is carried out taking into account the mandatory requirements:

• To install the machine, parallel bars or a concrete base without pouring the rails are used. The place is protected by a canopy from precipitation.
• Equipment power supply connection according to specifications. The inclusion in the operating mode is allowed after phase control and grounding.
• Balancing rail tracks by level in horizontal and vertical directions.
• Ensuring the alignment of the rear and front headstock.

High organization of labor is achieved by zoning the site with the creation of places for storing blanks, finished products and lumber. Before starting work, the condition of the surface, milling cutters, drive belts is subject to verification and lubrication of working units is carried out.

Currently, a huge number of foreign and domestic machines for log rounding are presented on the market. But some are wondering if it is possible to make a cylindering machine with their own hands. A do-it-yourself cylindering machine is not uncommon, and it is safe to say that any new machine becomes homemade over time, because each master brings it to himself.

Do-it-yourself rounded log

Round logs in the construction market are represented by many organizations and depending on the level of equipment used, each organization has a different product quality. In order to round a log, therefore, it will not work to make a rounded log with your own hands, since this is not a wooden frame, but a technological product that is practically independent of the human factor.
In production, the log is rounded by milling on special milling machines. There are two types of such machines: broaching machines and center machines with a more accurate rounding result. The broaching machine works on the principle of processing a log in the process of pulling it through the machine, more precisely through its cutting head, which rotates and cuts off the surface of the log. Such a machine has low accuracy, as it retains the natural curvature of the log along its entire length. This significantly affects the quality of the walls erected from such a log, since there will be a low density between the logs. The center machine ultimately produces a high-quality product in the form of a rounded log of the correct shape and size. On this machine, the cutting head selects the natural curvature of the log along its entire length, and the log is even. This is a good log for creating walls with low thermal conductivity due to the dense shrinkage of the logs to each other.
Production can be installed only in the enterprise, but not at home. And it is impossible to make a rounded log with your own hands using an ax and a chisel. If you cannot afford to buy a log processed at the enterprise, then there is only one option left - to use a wooden frame. It is less efficient in its characteristics than round logs, but at the same time it retains the same properties in terms of thermal conductivity and naturalness. In addition, a wooden frame can be made independently with the help of not tricky tools that every man knows how to work with.

Woodworking machine for cutting the crown "cup" stationary SZ-280

The marking and execution of the cups takes some time, during which the cylindering machine does not “round” anything, that is, it does not perform its main function - rounding the log. To increase the productivity of STs-6.5, MAGR offers machines for rounding, which are designed to make cups on rounded blanks.
Almost all currently existing "cup cutters" cut cups with cutters having a certain diameter, which requires the presence of standard sizes of cutters for all cup diameters in everyday life. The drive power of such "cup cutters" is quite large and ranges from 5.5 to 11 kW. The originality of the SZ-280 machine is that the cutting tool here is a narrow tape, the so-called. "jigsaw", saw

Machine for cutting the crown "cup" stationary SZ-280

This one is intended for cylindering and creating an element of transverse fastening of cylindrical parts - a “cup”, both perpendicular and at an angle to the axis of the log, which has undergone cylindering. The rounding machine offered by us makes it possible to make a cup of almost any diameter on rounded logs in the range from 160 to 280 mm without changing tools. Smooth adjustment of the cup diameter is achieved by rotating the handwheel with control on the scale.

Cups can be made on the machine at an angle of 90°±45° relative to the log axis. If necessary, you can do the so-called. "end" cup. The work is done by one electric motor with a power of 1.5 kW. The small dimensions and weight of the machine will give you the opportunity to install near the place of assembly of the log house.

One saw can withstand about a hundred cups made with a rounded log diameter of up to 200 mm.

Rounding machine / rounding machine is designed to produce rounded logs from roundwood and used for production. Due to the fact that modern machines are very multifunctional and equipped with a large assortment of various devices and tools, it is possible to ensure the implementation of all production operations for the manufacture of a log house with only one galvanizing machine.

Among the possibilities of machines for logs are also milling of a longitudinal groove and plane and selection of a crown cup. This functionality makes the cylindering machine a kind of mini-production for the manufacture of wooden. Processing of products on a rounding machine allows you to assemble a log house as if from designer parts, without subsequent fitting of parts. After processing on the machine, there is no need to grind the surface of the log or any other subsequent processing.
The main elements of the lathe-milling machine are the frame and the carriage moving along it. The workpiece, fixed at the ends between specially rigidly installed adjustable centers (headstocks), is rotated, while the combined cutter rotating at a high frequency begins to move along the log, thereby processing it. Longitudinal feed (moving the carriage along the frame along the log) can be either manual or electromechanical.

Do-it-yourself milling cutters installed on the cylindering machine allow, in addition to cylindering, to perform such operations as choosing a longitudinal mounting groove, choosing mounting bowls, milling a smooth inner surface walls, make a rectangular or square beam without reinstalling the log and tool. When using the saw unit (), also without removing the logs from the centers, you can make a compensation groove to relieve internal stresses that occur during the drying of the log.

To facilitate and reduce time when installing a log in the center, special mechanical levers are used that can be installed anywhere on the frame. When passing the mounting groove on small diameters (up to 200 mm), some deflection of the log is possible; to prevent it, a stop roller adjustable for the diameter being processed is installed on the side of the log opposite to the cutter.
When choosing a crowned bowl in a log, it is necessary to securely fix the carriage, for this mechanical braking devices are used, installed at both ends of the carriage and securely fixing it, in addition, a log fixing mechanism is installed to prevent its rotation when choosing bowls. When choosing a mounting bowl or a longitudinal mounting groove, a more precise (manual) adjustment is also required - for this, a mechanism for manually rotating the log is installed.

Engine power of the 2nd (traverse) carriage: 4 kW/h at 380 V
Weight (with rails 12 m long for rounding 8 m logs and 2 carriages): 1,200 kg

Operations performed on the machine:
- Production of profiled timber - Production of rounded logs - Sawing the gun carriage into an edged board (up to 1.5 cm)
- Sawing logs with a diameter of up to 8.5 cm into a carriage and a board ()
- Production of blanks for end parquet
- Manufacturing of moldings (in-house), thicknessing - Manufacturing edged board from unedged

The purpose of the machine model "F-1" - manufacturing wooden parts in the construction of houses, as well as the installation of prefabricated houses, performing cylindering, profiling longitudinal sections of parts, making a flat edge and a thermal lock (in the manufacture of profiled timber), cutting cups in all places of a rounded log, at any angle to its longitudinal axis.

The rounding of the log is carried out by rotating the workpiece and simultaneously moving the carriage along the log with milling tool; a thermal groove is obtained on an immovable log (the main drive for feeding the carriage and spindle is turned off) by changing the position of the carriage with the milling tool; obtaining a flat edge and cutting out cups is carried out using the milling head of the second carriage, while obtaining a flat edge, for the sake of economy, the cutter can be replaced with a circular saw, which makes it possible to obtain a blank for the production of a block house.

It is possible to cut cups directly on the construction site. This machine does not have a metal-intensive and solid bed. There is no need for a trimming operation when harvesting, it is possible to process crooked trunks and trunks with knots that protrude up to 7 cm from the intended surface to be processed. The machine allows efficient use of wood without prior selection. The machine has steady rests for adjusting the support force and reducing the vibration of the log when processing inhomogeneous surface layer and high processing speed.

The quality of the surface being machined primarily depends on the degree of sharpening of the cutting edges. The axis of the log and the cutting edge of the cutter in the horizontal plane look like intersecting straight lines. Although modern housebuilding requires subsequent polishing of the log to obtain a highly decorative look, this machine makes it possible to perform both roughing and finishing in one pass during rounding. The machine is very reliable and simple in design.

Since ancient times, mankind has been using trees to build housing. This material is widespread, does not require complex preparation and retains heat well. Currently, the tree can be subjected to any processing to give the desired shape to the log. To obtain even logs with the same cross-sectional area, rounding machines are used.

Such an installation allows you to carry out various wood processing operations:

1. Tree rounding.
2. Groove making.
3. Edged board production.
4. Obtaining elements for parquet.
5. Cutting boards.
6. Beam production.
7. Milling of a smooth log.
8. Sawing wood on a gun carriage.

Rounding machines are used in sawmills, large industries and in private households. The main function of the equipment is to remove the top layer of wood through the use of a cutter and various types of knife tools.

Varieties of cylindering equipment

Depending on the technology, the log rounding machine is divided into:

• Checkpoint - carries out the processing of wood during movement, without stopping.
• Cyclic - when processing wood, the movement of the log is interrupted. The movement scheme is a cycle of operations.
• And also cyclic installations are classified into two subspecies:
• Cyclo-positional - the processing of the material occurs in the process of moving towards the tool
• Cyclo - through - wood is subjected to woodworking with a tool that itself makes the necessary movements.

With the pass-through processing method, the log produces a linear movement, and the machine rotates. And the cyclo-through equipment provides for the movement of the log with respect to the axis, and the movement of the tool occurs by torsion. Cyclo-positional machines carry out rotating movements of the log, and the tool performs a rectilinear movement parallel to the axis of the workpiece.

According to the mechanism of operation, the machines are divided into:

1. Mechanical - assume the presence of an operator who adjusts the modes, configures, loads and unloads equipment.
2. Automatic - the entire processing scheme is performed by the machine. There are models where a person only needs to load the material.
3. Semi-automatic - the installation automatically performs only one cycle of operations, and then the person must start the mechanism again.

The machine for rounding logs in the case of a separate type gives different performance. Passage equipment is more productive, but inferior in terms of correct processing and the formation of pronounced roughness of the material.

Cyclo-positional installations give good clarity and high quality, but the output is much less. If we compare in terms of the occupied area, then much less space is needed to accommodate cyclo-positional equipment than for walk-through installations.

Features of machine tools for cylindering

The installation consists of the main blocks - a metal frame, front and rear headstock, milling cutters. Usually used as a frame square pipes having guides for the movement of the power structure and the carriage. Headstocks are required to secure the log in the central part and to push the rotational action.

Milling cutters are the main running tool. They provide easy entry into the wood, reducing vibration and increasing accuracy. They are versatile and curly. The universal cutter is used for classical rounding, milling and selection of crown cups. The curly cutter is used when sampling grooves.

The cutters are equipped with knives that can be removed. If the resulting parameters of the log do not match, it is necessary to replace the knives. They are made of durable steel and are used for a long time.

To reduce the time and make it easier to place the log on the frame, levers are used that are installed in the center of the log. To select the crown cup, you need a secure attachment of the bottom bracket. Therefore, braking devices are used, placed at the ends of the carriage. If you need to get a longitudinal groove, then use a convenient wood rotation regulator.

The choice of a machine for the production of rounded logs

To select a machine, you should not rely on advertised settings. It is necessary to evaluate the proposed samples well. Of course, it is useful to visit the factories where such machines are used. Communication with the direct operators of the equipment will bring good results when choosing an installation.

On Russian market the following models are widely represented: Rus, Sherwood and Termit. Sherwood and Russ equipment can be separate components, or be part of a woodworking system. The volume of the log that passes through these installations is 24 cm. There are models that allow large diameters. These settings are used for processing various materials: birch, oak, ash, pine and others.

Of course, you can buy popular machines, but sometimes you have to remake them for your own needs. Therefore, a more practical way is sometimes the manufacture of a cylindering machine with your own hands.

Independent manufacturing of a machine for working with wood

A home-made cylindering machine is preferably performed using a sawmill. In order for the log to rotate, an electric motor is used, which is installed additionally. Instead of the front conical conical part, an emphasis is made, the bearing for which is the headstock located at the back.

The manufacture of the cutter occurs by collecting from the constituent elements. For the movement of the cutter, a rail is used. The installation resembles a milling machine, since the installation of the log takes place in the existing grooves, then torsion occurs. As a result, the cutter begins to move along the log.

A homemade rounding machine is mounted on a hard surface, preferably concrete. In the manufacture of the frame, sleepers or thick timber are also used.

Stages of machine assembly:

• Assembling the frame, using a level to place it in a stable horizontal position. Usually the height of the frame reaches 20 cm.
• Mounting of the power structure (front and rear headstock), on which the cable for attaching the electric cable is pulled.
• Equipment of power racks with a stopper.
• Providing grounding.
• Connecting a motor that causes the log to twist. In this case, you should focus on the exact connection of the phases. If connected incorrectly, the direction of the power head will not match the direction of the buttons.
• Checking the direction of torsion of the log. If the direction is wrong, it is necessary to replace the phases on the electric motor. It should be remembered that until the power phases are correctly connected, the rotational actions of the log and the engine are prohibited.

And also it is necessary to firmly fix the headstock, installing them simultaneously with the guides. The lines of movement of the axes of the racks should be similar. To do this, the exact length is measured between the longitudinal profile and the central part of the rack and between the nearest rail and the center of the headstock. These distances must be equal for both attendants.

The milling cutters are installed on a conical element, and they are fixed with bolts. It is necessary to maintain the balance of cutters and change the jump in sharpening knives.

After all installation operations, check the correct assembly and the horizontalness of the frame.

After a long period of standing without work of your machine or being in a humid room, you must withstand the installation in a dry room before starting to remove excess moisture.

Advantages of a homemade machine

A do-it-yourself cylindering machine has certain advantages:

1. Small amount of wood.
2. Obtaining material for any own needs.
3. Achievement good quality received log.
4. Having a machine handy.

Of course, like any purchased machine, homemade equipment requires the purchase of spare parts. But the processing of wood on their own equipment turns out to be more suitable for the personal purposes of using the resulting log. Achieving certain technical properties for products occurs in the presence of home-made cylindering equipment.

Own sawmill in household- production is extremely useful. Wooden house and the site require constant work and updates, but at the same time it has a lot of disadvantages: rot, damage, burning. In order to replace one of the elements of a house or outbuilding in time, material is required. Bringing it is sometimes just expensive. That's why homemade machines logs will come in handy for rounding. Types, advantages and disadvantages are described below.

factory production

At present, log cylindering is produced by high-precision equipment in one cycle of processing natural unbarked logs. Such technical innovations are not cheap, but they fully justify themselves - the owners of the forestry and house-building business confirm a seven-fold payback. Aspiring entrepreneurs are not able to immediately acquire the innovations of progress, and therefore they use the following types of devices:

Each of the machines requires a special room for the unhindered shipment of finished products and the availability of personnel for maintenance and repair. Therefore, private farms prefer to arrange home-made equipment that produces high-quality whips for self assembly log house.

Homemade installations

So that home-made log rounding is not inferior in quality to production, collect own mechanism according to all the rules, take into account all safety issues, otherwise, in the absence of experience, the risk of breakdown or health hazard increases. The requirements for a homemade installation are as follows:

To assemble a home-made machine for log rounding, it is important to have a similar experience and understanding of the operation of each node. Otherwise, a mechanism that has an electric drive will become dangerous.

Installation

For work, an old sawmill is used, on which the body is replaced with an emphasis and tailstocks for clamping an unbarked trunk. A tapered or other roller bearing is installed as a holder. In order for the log to easily rotate along its own axis, an additional engine is required; manually, the process will take a long time.

To move the cutter, the most simple solution will be the laying of the railroad track. No need to drag heavy whips by hand. The distance between the transverse sleepers that reinforce the structure and on which the rail is attached is no more than 1 m; for installation, a beam impregnated with special compounds or ready-made sleepers is used.

Installation of a home-made machine for cylindering begins with the assembly of the frame. Acting welding machine, prepare its sections separately. And during assembly, they check with a level so that the structure is in the same plane. An error of 0.5 mm per meter is allowed, since it will still not be possible to achieve perfect evenness, and a heavy log will smooth out the discrepancy in the future.

Strengthen the milling unit, assembled from the details of the lathe. Indeed, in addition to cylindering, you need to cut a cup on the trunk. This requires a special vertical cutter, which is made independently or ordered from the manufacturer's catalog.

For the formation of the laying groove and the compensation cut, the corresponding accessories are required. Suitable circular saw. Install it on the side of the milling unit.

Now connect the motor for rotation. Immediately provide a power supply with the recommended voltage in the room intended to be a home sawmill, power cable must go separately and be connected to an independent shield, otherwise constant knocking out of household appliances in the house cannot be avoided, which cannot affect their work. The engine is reinforced with anchor bolts. The correct connection is indicated on the body, the movement of the power head must coincide with it. In case of mismatch, reverse the phases.

Cables for connecting various nodes are installed at full length finished machine with a margin. Safety of use lies in strengthening them over the machine flexible holders. Don't let the cable sag, let alone touch working surface- Overshoot is fraught with consequences.

Before starting work, the machine for rounded logs is checked for parallelism of the axes of headstock, front and rear. The repositioning cutter must run exactly horizontally. If this is not done, the smallest trouble that occurs during operation is the curvature of the barrel. Big - failure of the entire system. In addition, the error of parallel lines leads to the play of the log, especially with poor fixation.

Operation and care

On production areas, the production of a finished log can be up to 800 m per shift. At home, this is hardly possible, and it is not necessary. To get several pieces of high-quality OCB for future construction per day, follow the rules for safe operation and carry out preventive maintenance in a timely manner. So:

Do the current and overhaul homemade installation for rounding logs. Complete disassembly in the first option may not be necessary if the preventive maintenance was carried out on time. At this stage, bearings, bolts, fasteners are replaced, the sharpness of cutting tools is checked and, if necessary, they are changed.

Overhaul is carried out only by the efforts of a specialist in the maintenance of electric motors and an assembler. That is, the power unit is removed and sent to the workshop. Doing something yourself, in the absence of knowledge and experience, is not recommended. You can only replace bearings on a rotating shaft yourself.

The construction of housing made of wood in our great power has been developed since ancient times. First of all, this is due to the colossal reserves of this environmentally friendly and relatively inexpensive material. Despite the emergence of many new construction technologies, classic log cabins are still popular. After all, the advantages of rounded logs are obvious, they will be discussed further.

Photo of the construction of a classic log house.

Why the log

To begin with, let's find out what a rounded log is and why the vast majority of people prefer to build housing from it.

Important: speaking in a dry language of definitions, it is customary to call a log a straight tree trunk, pre-processed on woodworking machines to give it the correct cylindrical shape. As a result, the upper uneven layer, knots are removed, and compensation and mounting grooves are applied.

Scheme of a rounded log.

Material advantages

• Wood itself has a natural porous structure, as a result of which it is one of the best warmth and soundproofing.
• With clear geometric dimensions, this material fits perfectly with each other. Specially equipped grooves provide high tightness and quality of interventional seams.
• All trunks have a clearly fixed diameter, the maximum deviation here can be no more than 2 mm. This makes it possible to choose a forest for the construction of premises for various purposes with specified characteristics.
• On this moment there is simply no more environmentally friendly and useful building material for people. Unlike wood, traditional bricks or modern types of building materials can only boast of environmental neutrality.

Product calibration.

• Although the price of a rounded log may be higher than that of many competitors, such houses do not need additional internal and outer lining. This material in itself has a natural beauty, as a result of which the owners significantly save on finishing.
• Modern woodworking equipment allows you to initially produce trunks with ready-made connecting elements. This greatly speeds up the process of building structures and gives a lot of planning options.

Laying scheme.

• You may have heard that natural wood breathes. By this is meant the ability of the array to take from the air excess moisture and give it away when conditions change. Simply put, the tree is a natural conditioner, providing an ideal microclimate for human life in the house.
• And finally, the building instructions are quite accessible. A simple bathhouse, a barn or a small country house, a good owner, with a great desire, will be able to build with his own hands.

Some characteristics of products.

What are the disadvantages

• As we have already said, wood is a living material, so over time, the array begins to dry out and crack. This is true, but thanks to modern impregnations and primers for wood, such processes can be significantly slowed down.
• Many people know that in the process of growth, the trunk of a tree twists slightly in a spiral. After the cut, this spiral sometimes begins to unwind. That is why the masters do not recommend building from freshly sawn wood, structures can lead. But a dry rounded log is devoid of this drawback.
• Disadvantages such as high fire hazard and susceptibility to biological pests are easily eliminated due to the same specialized impregnations.
• Perhaps the only significant drawback of any wooden structure is a high percentage of shrinkage of new homes. Well-dried quality wood shrinks up to 100mm for every 3-4m of wall in the first year. And 10 - 20 mm for another 2 - 3 years. Freshly sawn wood will shrink up to 10 years.

The structure of the log.

What affects performance

To determine the main parameters of the material, there is a set of regulations. In our country, this is GOST 2708-75, in the west, ISO 4480-83. There is no big difference between them, the main parameters are identical. It is on these data that such a program as a rounded log calculator of volume, weight, density and other characteristics is based.

Array volume table.

Tip: it is desirable that the table of the volume of rounded logs be original, that is, taken from the above regulatory documents. Since now there are many corporate tables compiled taking into account the commercial interests of some corporations and containing inaccuracies that are beneficial for those who compiled them.

Machine tools and equipment

Even 50 - 100 years ago, every carpenter or just a good owner knew how to round a log at home. In view of the fact that this occupation is long and very laborious, with the development of woodworking production, there are not so many real specialists left.

Technological line.

Of course, in a dispute that a log or rounded log is cheaper, an ordinary raw trunk wins. But line up good house or a high-quality bath from "wild" material is almost unrealistic. Apart from the time spent on handicraft cylindering and laborious installation, you will not be able to hermetically equip the seams and joints. Accordingly, the room will be cold and will not last long.

The machine for cylindering logs is, in fact, a symbiosis of milling and turning functions. Such equipment has impressive dimensions and includes a common metal frame on which they are based, a power unit, which can consist of several power plants.

The main work is performed by the headstock. It is on it that cutters for peeling the top layer and curly cutters for finishing logs are installed. The tailstock, as in most such equipment, serves to fix and feed the workpiece itself.

Factory machine.

If you want to know how long a log is made, then in this case it depends on the quality and functionality of the equipment. Modern automated lines are capable of turning a high-quality calibrated product from a natural log in a matter of minutes, according to the specified parameters.

All such units are of two types - through passage and cyclic. The former are designed for large production volumes and have a minimum of functions. In them, the material moves in a continuous stream and, passing through the working area, is cylinderized and milled.

Installing the workpiece on the machine.

Aggregates of cyclic type perform a given algorithm of actions, after which the cycle repeats. They, in turn, are divided into cyclo-through, where the barrel moves, and the carriages are in a fixed position. And cyclo-positional, where the log is motionless, and the carriages move around the workpiece.

As a rule, a do-it-yourself machine for a cylindrical log is made on the basis of a sawmill, where an emphasis is placed instead of the front cone, and the tailstock is changed to a bearing or a rotating cone. The workpiece fixed in this way rotates due to an additional drive or with your own hands, which is very difficult and inconvenient.

Kustanai machine.

Processing is carried out by a milling head mounted on separate guides. The very principle of operation of such a handicraft unit resembles the work of a milling machine for wood. A rotating workpiece is gradually processed by a milling cutter moving along the guides.

Tip: in view of the serious weight of the blanks themselves, experts recommend rigidly mounting such equipment exclusively on a concrete base. If this is not available, as an option, you can put reinforced concrete slab for covering.

General scheme of the machine.

A few words about the characteristics

Domestic production is more focused on the so-called lunar profile of round logs. It has a mounting cup for connecting the crowns and a compensation cut.

This cut serves to compensate for the natural internal stress of the array, as well as temperature and humidity expansions. In the manufacture of such a product is cheaper, plus it does not require careful pre-training material.

Profile types.

The Finnish profile provides a tighter connection of the crowns, so less sealing materials are needed, but the log requires thorough drying and preparation, as a result, the price of the Finnish profile is higher.

The working height of the rounded log is 6 meters. This does not mean that products cannot be larger or smaller.

It's just that most production lines are oriented to this size. An increase in height entails an increase in cost. The price of smaller barrels depends on the quality and complexity of processing a particular product.

Storage of goods in a stack.

As for the diameter, the working range here ranges from 160 to 320 mm. Rounded logs of 400 mm or more are processed on special machines. Such a non-standard product is used to equip the root crowns of the building, as well as other important load-bearing nodes. In addition, the walls of the first floors for multi-storey cottages are sometimes erected from logs 400 mm in cross section.

The cost of goods is strongly influenced by the method of drying the array. Natural drying takes place for about six months under open sheds in natural conditions. Such a product costs less, but its shrinkage is higher.

Chamber drying provides processing of material in special high-temperature chambers. Such a log shrinks less and is considered to be of better quality.

Important: relatively recently glued logs have appeared on the market. The price of such products is much higher. But, according to experts, they have exceptional quality.

Stem processing.

The video in this article contains materials on this topic.

Conclusion

As a business, round logs are considered a very profitable option. To launch an average production line with a standard assortment, about half a million rubles are needed. In this case, the payback often does not exceed a year.

Features and installation of the machine for rounding logs | Construction portal

It so happened historically that since ancient times, people have built their homes from wood. This is quite easy to explain by the ease of processing, the availability of acquiring such a material and excellent heat-conducting properties. After many years, with the advent of new technologies, wood began to be processed using special machines. To obtain rounded logs of the same diameter and length, a special woodworking machine is used to round the logs.

Features of the rounding machine

The rounding machine is a woodworking machine that is designed for the production of rounded logs and profiled timber from roundwood and for the manufacture of log cabins. The rounding machine makes it possible to perform all the operations that are provided for by the log house production technology: to make a selection of mounting grooves, a crown cup, to round the log (primary and secondary processing) and to perform milling smooth surface.

And you can also use the machine to perform such operations as sawing a carriage into edged boards, sawing a log into a carriage and a board, making moldings and blanks for end parquet, obtaining an edged board from an unedged one.

When using the saw unit without removing the log from the center, you can make a compensation groove to relieve internal stress that occurs when the log is dried. All these operations are performed on the machine sequentially with one set of tools for one installation of the log. Because of this, when producing a finished log, there is no need to reinstall the cutters and the log.

The combination of different processing modes makes it possible to obtain products of a rather complex configuration - balusters, beams of a complex profile and with different diameters. The formed geometric profile allows you to build wood structures of any complexity. In addition, the log rounding machine helps to process material with a length of 7 meters.

The design of the machine for rounding logs

The rounding machine includes the following blocks: a common metal frame made of square pipes, on which guides are installed, which are intended to move the power unit and the saw carriage along them. On the common frame there are also headstock and tailstock, which are needed to install in the centers of the original workpiece and drive the log into rotation. On the headstock there is a dividing head that serves to fix the log in different positions, as well as a spindle head for rotating the cutters.

As a working tool, cutters of a special design are used - curly and universal, which are installed on the spindle shaft of the machine. A universal cutter is necessary for rounding, plane milling and selection of crown cups. The curly cutter is intended for sampling the mounting groove. Technological feature milling cutter, which is used on the machine, is to provide a "soft entry" into the treated wood surface. This leads to a reduction in vibration and also increases the accuracy of the work.

The knives used in cutters are removable. If the operator sees that the required size of the processed surfaces is not maintained, then the removable knives need to be sharpened. Removable knives are made of high-quality tool steel, which makes it possible to use one set of them for a long time, and at the same time, the resource of the cutter itself is not limited.

To reduce time and facilitate installation in the center of the log, special mechanical levers are used, they can be installed on the frame at any place, as shown in the photo of the log rounding machine. When passing on small diameters (up to 200 millimeters) of the mounting groove, some deflection of the log may be observed;

When choosing a crown cup, a reliable fixation of the carriage is required; for this purpose, mechanical brake devices are used, which are placed at both ends of the carriage and securely fixed. And there is also a special mechanism for fixing the carriage, which does not allow it to rotate when choosing bowls. In the manufacture of a longitudinal mounting groove or a bowl, very precise (manual) adjustment is also needed - for this purpose, a special mechanism for manually rotating the log is installed.

Classification of rounding machines

Rounding machines for logs technological schemes can be divided into two types:

1. Passage devices with continuous movement of logs. The log in through machines is processed while moving in the tool area without stopping. The movement of logs can be carried out without a gap or with a gap between the ends of adjacent logs.
2. Cyclic devices with intermittent movement of logs. For one cycle of processing in cyclic machines, a repetitive set of movements occurs. Cycle machines are divided in turn into two types:
   • Cyclo-pass rounding machines: the log is processed by a cutting tool that makes working movements;
   • Cyclo-position rounding machines: the log is processed while moving relative to the area of ​​the working tool.

Each combination of movements makes it possible to determine the kinematic scheme of cutting by different processing methods. The work of the machine is represented by the following combinations of movements of the log and the working tool: rectilinear and two rotational, rectilinear and rotational.

The log, when processed in through-hole cylindering glasses, makes a rectilinear movement, and the tool, respectively, rotational. The log in cyclo-through machines at the time of processing along the axis of the log makes a rectilinear movement, and the tool in position - rotational, as shown in the video about the machine for rounding logs. The log, when processed in positional lathes, produces a rotational movement, and the tool itself (cutter) moves in a straight line, parallel to the axis of the log.

Depending on the shape and type of the tool and its cutting edges, all types of log processing can be divided into two types - milling and turning. Turning is characterized by a constant process of chip formation. The main movement that occurs at a fairly high speed when turning is the rotation of a tool or log. Milling is characterized by an inconsistent chip formation process. In milling, the main movement is the rotation of the tool.

Woodworking machines in our time, according to the degree of automation and mechanization, are divided into the following classes:

1. In mechanized machines, the main movement and feed movements are performed without human intervention. The operator provides regulation, adjustment and unloading, as well as loading the machine.
2. In automata (automatic machine tools), the entire range of movements and operations is performed by the machine. A person is assigned the role of monitoring the work and periodically loading the machine with workpieces. In full automatic machines, the loading of workpieces is also automated.
3. In semi-automatic machines, operations are automated only within one cycle, and human participation is required to complete the next processing cycle.

Comparing different log rounding machines, we can say that not only the price of log rounding machines differs, but also their functions:

• Through-type machines have high productivity, but at the same time they demonstrate low machining accuracy and a rather large surface roughness due to the lack of a basing system;
• Cycling positional devices guarantee high accuracy and have excellent surface quality, but their output capacity is much less than pass-through devices;
• Cyclic positional machines have a reliable basing system, occupy a rather small production area and are widely used in production.

Do-it-yourself installation of a cylindering machine

Usually home-made machines for rounding logs are made on the basis of sawmills. The front cone is replaced with an emphasis, and on tailstock Install a thrust bearing or tapered roller bearing. The fixed log is rotated with the help of an additional motor, or manually, which is not so practical. Making a cutter is the most difficult. In order to complete the task as easily as possible, it is made in typesetting, that is, it is assembled from several elements. It should be noted that the material of the cutter itself must be strong, that is, soft alloys are not suitable for these purposes.

Most in a simple way to ensure the movement of the cutter along the log itself, it is considered the laying of an additional rail track along which the installation will move. This will make it possible to exclude manual dragging. The principle of operation of such an installation is similar to the principle of operation of an ordinary milling machine, when the workpiece, fixed in poses, rotates, and the cutter moves along it.

Remember that it is recommended to install a machine for rounding logs with your own hands on a concrete platform. It is also possible to operate the rounding machine on compacted soil. In this case, install the machine on the transverse rails wooden sleepers- for example, a bar with a section of at least 1500X1500 mm. The recommended distance between the sleepers is one meter. It is also necessary to exclude soil shrinkage in places where the machine will be installed.

The machine begins to mount from the assembly of the frame. It is necessary to assemble the frame sections and install it at an even level in one horizontal plane. Adhere to the installation error of no more than 0.5 per 1000 millimeters - both across the guides and along.

When installing the frame on a concrete platform, the frame is mounted at a height of approximately 15-20 centimeters, and the joints of the sections are concreted. On installed frame a power unit, front and rear headstocks, racks are mounted on which a cable is pulled for attaching an electric movable cable. A clamp-stopper is installed on the power unit. The machine is also grounded to common system grounding.

Next, the motor is connected, which rotates the workpiece. Connect the machine to the mains, check the correct connection of the phases of the power supply to the corresponding power modes. To do this, press the button for raising and lowering the cutter. If the actual direction in which the power head moves coincides with the same direction as indicated on the control panel, then the power supply has been connected correctly. Otherwise, the phases must be reversed.

After that, you need to check the direction of rotation of the workpiece. When the direction of rotation is wrong, it is necessary to reverse the phases on the motor. It is forbidden to turn on the workpiece rotation motor and the cylindering machine motor until the correct connection of the power supply phases has been checked.

If you, after you have made a machine for rounding logs, perform the initial start-up more than two months later, after a long break, or the machine was in storage and during transportation in a condition of high humidity, then it is necessary to keep it in a dry room for some time before starting it up. removing moisture from electrical equipment.

Remember that the front and rear headstocks of the log rounding machine must be placed parallel to the guides and, according to the selected length, be rigidly fixed. In addition, it is necessary to check the alignment of the tailstock and headstock of the cylindering machine. For this purpose, measure the distance to the nearest millimeter: between the vertical longitudinal profile and the center of the headstock, between the near guide and the center of the headstock. It is necessary that these distances be the same for the tailstock and headstock.

Misbalancing of cutters and changes in the angle of sharpening knives can lead to failure of the cylindering machine, or to deterioration in the surface quality of the product. The curly cutter is mounted on the conical part of the shaft and fixed with a bolt. A universal cutter is screwed into the body of the curly cutter and then tightened with a special key.

In addition, if you have made a machine for rounding logs, check that the frame is mounted correctly and horizontally. By laying gaskets under the rear one, it is possible to determine the parallelism of the axes of the rear and front headstocks with the plane of movement of the cutter. The thickness of the gasket should be equal to half the taper value.

Do-it-yourself cylindering machines

People have been working with wood for a very long time. Since that time, the use of this raw material has only gained momentum. Currently, there are entire facilities involved in wood processing. However, skillful owners can assemble some devices on their own, if they need to. in large numbers handle wood. Enough useful device became a rounding machine.

Purpose of equipment

The main purpose of this machine is that it is used to give the correct shape to those logs that go to the construction of log cabins. Naturally, the workpiece can be carried out manually, but the use of an automated device greatly speeds up and facilitates the whole process.

The rounding machine has the following functions:

• prepares grooves in logs for further installation;
• performs rounding of the material;
• used for the production of edged boards from the gun carriage;
• it is possible to prepare dies for parquet;
• it is possible to carry out milling of smooth wood;
• cutting unedged boards;
• production of a bar of the necessary sizes.

In addition, this equipment can create expansion slots using circular saw and the raw material processing speed is customizable.

What is the unit made of?

The rounding machine includes several of the following components:

• A metal frame, which is most often made of rectangular type pipe.
• Necessary guides for moving the power and saw device.
• Headstock used for fastening, as well as torsion of a log. The headstock must be equipped with a dividing head that fixes the barrel. The spindle head will also be mounted there.
• The milling cutter is one of the key elements. If the cutter is of a figured type, then it can be used to make a groove for mounting, but if it is universal, then it can be used for rounding, cutting crown cups, and processing planes.
• Removable cutter blades will also be an important element. They must be made of good steel. The main convenience is that they can be replaced without removing the cutter itself.

Varieties of aggregates

To date, there are several types of rounding machines.

Through-type machines provide a constant movement of the workpiece on the table, processing it at the same time. There are also machines of a cyclic type, the movement and processing of which goes through several cycles. In addition, this type of equipment is divided into two more - these are cyclo-through and cyclo-positional. In the first case, the wood blank remains stationary, and the cutter moves; in the second case, on the contrary, the processing tool does not move, the wood moves.

It is also worth noting here that the division of machines is carried out according to the level of their automation. There are mechanical, automatic and semi-automatic machines. If a mechanical type of machine is used, then the loading of the material and the setting of all processes are carried out by the operator. In automatic machines, all this happens without human intervention, you just need to control the progress of work. Semi-automatic machines are able to control only one stage of work, then operator intervention will be required.

A little class comparison

Rounding machines of the through-type type are distinguished by their high performance, however, they also have a certain error in the process of work, and the surface may remain slightly rough.

Units related to the cyclic type process the surface much better, as well as perform other operations, but this significantly affects performance.

However, it is worth noting here that it is the second category of devices that has received more widespread use. Since they are more compact, and their base is considered more stable.

Do-it-yourself cylindering machine

Most simple option assembling such a device with your own hands will use a sawmill as a basis. Instead of the front cone of the equipment, it is necessary to install a stop. The headstock, which is located at the back, will be equipped with a bearing for this part. In order to rotate the workpiece, you can use an electric motor or a handle.

The greatest difficulty is the manufacture of the cutter, and therefore they try to assemble it from several separate elements. It is very important that the material used for this part must be very durable. To move the cutter, an additional rail is used, which also needs to be installed. The final device is very similar to the usual milling machine. The workpiece fits into the grooves and rotates, and the cutter moves along. Cylinder machines work in the same way.

Assembly steps

The first step is to assemble the frame. The installation height of the frame is 20 cm. The tilt error is allowed in the region of 0.5 mm per 1 meter. The second step is the installation of the power mechanism, as well as the fastening of the attendants. Next, you need to fix the cable for the electrical cable on the installed racks. After that, you can proceed to attach the stopper to the power mechanism. An important part of the work will be the grounding equipment for the device if it uses an electric motor. Only after arranging the grounding, you can start connecting the motor to power. When this is ready, it is necessary to check the correspondence of the phases to the modes of operation. If they were connected incorrectly, then when the motor is turned on, reverse rotation will occur. If this happens, then the phases need to be reversed. When everything is ready, you should once again check the correct rotation. It is strictly forbidden to lay a log before all verification work has been successfully completed.

Particular attention must be paid to the fastenings of the attendants. They are installed as rigidly as possible and parallel to the guides. The axes of both elements must match. It is also important to balance the cutter, otherwise the machine will fail quite quickly.
