Do-it-yourself wood lathe with a copier. Homemade wood lathe and copying machine with your own hands. Manufacturing of a turning and copying machine

In order to make a copier for a wood lathe, you will need the following components that will be necessary in the manufacturing process:

Electrical engine power approximately 800W;
metal shaft with a nozzle for changing the saw blade;
metal profile of square section, metal corners;
wood sheet;
furniture guides;
metal marker;
fastening materials.
welding machine, Bulgarian.

First you need to make metal guides.

They will allow you to move the entire copier structure in the longitudinal plane. In this case, two metal corners are used, which are turned over with the sharp side down. The corners are welded together into pieces metal profile.

This approach allows us to provide the necessary mechanical strength and eliminate the possibility of the guides bending under the weight of the copier. In practice, any other metal profile can be suitable for the manufacture of longitudinal guides, the main thing is that its mechanical parameters allow it to carry out the assigned tasks.

In this case, to make the base of the future copier, we used wooden box and board. The board is sized to allow movement inside the box in a perpendicular plane.

For fastening and subsequent movement, ordinary furniture guides are used.

The engine is attached to the board on top. In this case, the power of the electric motor is 800 W and the speed is 3000 rpm. Depending on your needs, you can use a motor with other parameters.

Next, the shaft should be secured to the board at such a distance that the belt drive normally connects two pulleys, one of which is located at the end of the motor shaft, and the second on the horse shafts of the saw blade. Applies here homemade shaft with one bearing.

A U-shaped structure must be made from a square metal profile. In the upper part of the U-shaped structure, a special metal holder of square cross-section is welded to the horizontal bar. The length of the holder must be less than the length of the marker.

To secure the marker in the holder, holes are drilled on the top plate. A metal nut is welded onto each hole and a bolt is screwed into it. Two bolts will be enough for reliable fixation. The adjustable marker is very convenient when changing saw blades of different diameters.

Easy enough to install required disk and use a plumb line to align the marker with the edge of the disk. The marker mount must correspond to the position of the saw blade in all planes. This allows you to simply move the marker along the prepared template to coaxially move the disk along the rotating workpiece.

The entire machine is assembled from two channels and metal corners for the sheath. On which a motor is mounted that rotates a wooden piece. In this case, an electric motor with a power of 1200 W is used.

Can be used as a frame old frame from some other machine. For ease of operation, it is better to place the engine on a removable metal plate, which allows you to move the structure with the workpiece, as in vertical plane, and horizontally.

The clamping head is made of four metal plates in the shape of a rectangular parallelepiped. Two nuts are welded into the end walls of the clamping head, into which a metal screw is screwed. A cone with a cartridge is installed at the end of the screw.

In cases where you need to eliminate the possibility of contamination of the surrounding space with sawdust from the operation of the machine or to minimize the percentage of contamination, you should make a hood.

The saw blade is covered with a metal casing, to which a flexible corrugated hose and a compressor unit are connected to create an air flow of a given power.

Lathes and copying machines are used to make many identical parts, for example, balusters for stair railings, fence posts, etc. You can make a functional design with your own hands, using devices that are unnecessary on the farm.

Making a lathe

homemade turning and copying machine

The most primitive model of a lathe is made from conventional drill. But this is not the only solution. Main parts of the future device:

bed;
front and rear pillars (headstocks);
electric motor;
master and slave centers;
tool rest.

The bed is the base for placing all elements and mechanisms. Therefore, it is made of thick timber or metal. The headstock is securely fixed to the base; the part will be attached to it. The front pillar houses a device that transmits movement from the electric motor to the driving center and then to the part.

The rear post (headstock) moves along a guide on the bed; it holds the free end of the workpiece. A tool rest is placed between the headstocks. The headstocks must be positioned strictly along a single axis.

For a do-it-yourself machine, an electric motor with a power of 200 - 250 W, with a speed of no more than 1500, is suitable. If you plan to process large parts, more than powerful engine.

A faceplate is placed on the electric motor pulley, which secures large workpieces. The faceplate contains points on which the part is pressed. The opposite end of the part is fixed with a corner.

To turn ordinary lathe in the copier, an additional device is required - a copier.

Copier for lathe

The basis of the copier will be an unnecessary manual frezer. It is placed on a surface made of 12 mm plywood, the size of the platform is 20 x 50 cm. Holes are made in the platform for fasteners and cutters, and stops are installed - bars for fixing the cutter. The router is placed between the clamps and secured with a pair of large nails.

The remote part of the platform moves along the frame along a guide - a pipe. Its ends are fixed in wooden blocks. The bars are attached to the frame with self-tapping screws. When fixing the pipe, you must use a level and align the axis of the pipe with the center of the machine. Before installation, a pair of bars with holes are put on the pipe and can be easily moved along the guide. A platform on which the router is placed is attached to the bars.

The second important element is installed with your own hands directly on the lathe - a block in a horizontal position on which the templates will be attached. A 7 x 3 cm beam is suitable; it is attached to the vertical stands with self-tapping screws. The stands are screwed to the frame. The top surface of the block must clearly coincide with the axis of the machine.

When the copier is not in use, the block is dismantled, the platform with the milling cutter is moved back and the machine turns into a regular lathe.

The stop is made of thick plywood and is attached to the work surface. In fact, the stop plays the role of a copier in this design. It is fixed vertically and fixed to the end of the working surface on a transition beam made of wood. The copier can be removed, it is installed on the stand with self-tapping screws. The stand must be fixed firmly, without the possibility of removal.

The templates are made of plywood and are screwed to the front surface of the block using self-tapping screws. The upper surface of the beam should be aligned with the axis of the template.

Disadvantages of the proposed design

The working surface with the router has to be moved with both hands, since during operation it warps and jams;
you can only copy enough simple elements, for example, it is impossible to repeat twisted patterns on posts;
to move the cutter it is more convenient to provide a screw drive;
It’s better to replace the cutter with a circular saw; such a device will be more universal.

Do-it-yourself lathe copier (copying lathe)

Making a lathe copy with your own hands is not the most difficult task. But in order to achieve the desired result in terms of quality and efficiency, you will have to make some efforts. You will need it detailed drawing, a copy template and a few hours of free time. We offer you a version of a copier machine based on hand cutter as a cutting tool.

Photo of a lathe copier with your own hands

The proposed copier for your lathe requires little financial, time and labor costs. This is what attracts him a large number of craftsmen who need a copier for a lathe.

The cutting device will be a hand router. At the same time, the operational capabilities of the copier directly depend on the characteristics of the copier itself. turning equipment.

You should not count on the attractiveness of the design of a device you create yourself, since its main task is to create copies according to a template without unnecessary energy consumption.

The device of the machine with a copier

DIY lathe copier drawing

To begin with, to create a lathe with a tracer, you will need a hand router. Choose its type yourself, depending on the planned work;
The router is mounted on a support platform with dimensions of approximately 50 by 20 centimeters. It can be made from 12 mm thick plywood sheets;
At your request, the copying machine can have a larger or smaller platform. The dimensions largely depend on the parameters of the selected router;
On the support platform, make holes through which the routers will come out;
Holes for fastenings are also made here. It is optimal to use bolts as fasteners;
Thrust bars located around the perimeter and fixed with self-tapping screws will provide protection against accidental movements of the cutter when processing products;
Having installed the cutter support between the bars, make sure that it is securely fixed and there is no vibration or play;
The far end of the support platform must be able to move along the guide pipe along the entire length of the turning equipment;
Use a guide pipe with a diameter of 25 millimeters, or adapt it to your machine parameters;
The main condition when choosing pipes is that they must cope with the loads from the weight of the router, not sag, and maintain an even, smooth surface;
Secure the ends of the pipes with a pair of wooden blocks of a suitable size;
The bars are mounted to the machine body with self-tapping screws or through bolts.

Installation of structural elements

In order for the lathe with a copier to work efficiently, and the copying process does not raise quality issues, do not rush in any case. It is precisely the rush that prevents craftsmen from making a really good copier for a lathe with their own hands.

Having studied the drawing on the basis of which you decided to build a copier with your own hands, stick to the suggested dimensions. If you make even a small error, the copying technology may be completely disrupted and the working axes may be disrupted.

To prevent anything like this from happening, stick to a few important rules.

The axis of the pipe intended for moving the router must be exactly parallel to the axis of rotation of the machine.
The coincidence of the pipe axis and the machine axis is also an important plus, although this condition is not mandatory.
The main point is the coincidence of the router in the lowest position with the axis of the turning device. This parameter is controlled and changed as necessary due to the level of placement of the copier.
Fix the guide pipe through the blind holes of the wooden blocks. But immediately before fixing, place two bars on the pipe on which you plan to install the supporting platform.
The wooden blocks for the load-bearing platform must move very easily, or rather slide along the guide pipe. If loosening is noticed, the copying unit will have to be redone.

Many fear the moment when increased demands are placed on gliding. But it’s not difficult to make a machine with such operating parameters if you use a smooth, smooth pipe.

Horizontal bars

The next step is to install the horizontal wooden block, which is the second most important operating component of your lathe with a tracer.

Adhere to similar precision requirements as in the operations described above;
The horizontal beam is connected to the workpiece profile template;
To make a block with your own hands, you can use a workpiece measuring 7 by 3 millimeters and fix it with screws to vertical posts;
Sami wooden racks mounted to the lathe bed using any method convenient for you;
Make sure that the top edge of the horizontal element is parallel to the axis of the machine and is located at the same level;
If at some point you don’t need the copying functionality, you can easily remove the block with your own hands, fold the mounting platform onto the edge of the machine and use the turning unit for its intended purpose without a copier;
A vertical stop is mounted to the milling table. A leaf will do just fine here. thin plywood. Although if you need more robust design, use steel sheets;
This element is used to move around the copier when sharpening parts. It sets the spatial position for the working milling cutter. Therefore, the copier should be fixed as securely as possible;
Important role thickness plays a role. The thinner the vertical stop is, the more accurately the lathe can copy your template. But even if the stop is too thin, the device begins to move according to the pattern with certain difficulties. Therefore, the optimal way out of the situation is to search for an intermediate option;
If you use plywood to make a copier, be sure to consider using a removable design. This will allow you to easily dismantle the copier when it wears out and replace it with a new one with minimal time investment.

Sample

The last but not least important element of a lathe with a copier function is the copy template itself. It is not difficult to make, but the configuration completely depends on the parameters of the products that you want to obtain using your machine.

Take a sheet of plywood or OSB board;
Apply markings on the sheet according to the contours of the future product that you want to turn on a lathe;
Be sure to compare all dimensions with the required parameters;
Electric jigsaw Using a cutting blade, carefully follow the contours, cutting out required part;
Sand the edges with a sander or regular sandpaper. The template should not have any irregularities, burrs or nicks;
Secure the resulting template to the horizontal rail using self-tapping screws;
Carry out fixation strictly in accordance with the installation parameters.

Using drawings and video instructions, you can easily make a fairly efficient, productive copy lathe unit yourself. You just need a little patience and time.

Wood copying machine: assembly of turning and milling equipment

All photos from the article

A wood turning and copying machine is a machine that is widely used in factory woodworking for replicating products of a certain configuration that corresponds to a given sample. This equipment allows you to process any parts with high precision and speed. However, production machines with their large dimensions will be difficult to locate in a small private workshop.

A huge machine easily copes with work that is beyond the control of a person

Copying equipment in woodworking

Many carpentry enthusiasts, gradually expanding their tool base and improving their skills, come to the idea of assembling a wood copy lathe with their own hands. After all, with the help of this device it is possible to make an exact copy of any piece of furniture and carry out restoration work.

Note! In most cases, of course, the main factor that encourages people to “reinvent the wheel” is the high price of a finished factory product.

The operating principle of a wood copying machine is quite simple:

The workpiece of the required size is clamped in a horizontal position.
We launch a device that forces the workpiece to rotate around its axis.
In turn, the movable cutter also removes excess wood, turning the blank into a product of the desired shape.

Similar products can be obtained by working on copying equipment

Structurally, the copying device for a wood lathe is whole line parts connected to each other, so there will be something to work on.

Personal assembly of equipment at home

Lathe

In order to assemble a small copying machine for wood with your own hands, you will need to make some effort and patience, as well as invest financially (about 7-7.5 thousand rubles). But this is several times less than the costs that await you if you purchase a ready-made option.

These are the masterpieces of interaction between hands and head found in private workshops

The model of small-sized equipment of the so-called beam type proposed for assembly can be divided into the following components:

Frame.
Slave and leading center.
Electric motor.
Front and rear headstock.
Stop for cutter.

Now we’ll tell you in more detail about how a wood copying lathe looks and is assembled:

It is clear that the frame is the foundation of the entire structure, on which all other parts will be based. Therefore, appropriate requirements are placed on it. It must be strong, stable and reliable. Therefore, it is better to make it from steel profile, but it’s quite suitable wooden beam large cross section. The electric motor and the driving center are connected to each other and fixed to the front of the base. Due to the electric drive, the blank is rotated.

Another option where the sampling depth depends on physical strength(pressing the handle, in the photo)

Attention! The selection of an electric motor for a copying device for a wood lathe is carried out taking into account the size and complexity of the parts planned for production.

For the simplest tasks, a 200-watt unit will be sufficient.

The headstock serves as a stop for the workpiece, so it is permanently attached to the frame.
By moving the tailstock along the frame, the workpiece will be transformed into a part of a given sample.
A stop for the cutter is installed between the tailstock and the front headstock, which will serve as a holder.
The tailstock and front headstock and the stop for the cutter are mounted clearly along one line.
All components of the machine must be securely fastened with bolts.

Fasteners should be chosen only new, galvanized, tightening everything individual elements with force so that the connection does not come loose. And wood turning and copying machines should be installed only level to avoid the slightest vibration.

Milling machine

If desired, you can also assemble a homemade copy machine milling machine on wood with your own hands.

Such a device is capable of:

Planar milling for creating profiles.
Volumetric milling for the design of reliefs.

A copying cutter for wood made of carbide metal reproduces the surface or contour of the master copier on the product.

The following is used as a copier:

Spatial model.
Flat template.
Reference model.
Outline drawing.

The simplest milling copier consists of a supporting frame - a base, a work table and directly a milling head equipped with an electric drive.

A hole is made in the center of the board and a router is attached in place of the hole, only on the reverse side

The dimensions of the desktop depend on specific tasks, under which the copy milling machine is assembled, as well as on the dimensions of the working room.
Based on the nature of the work and the dimensions of future products, methods for fastening the workpieces and template are determined.
The power of the electric motor that rotates the cutter is also selected taking into account the planned loads.

Advice! For milling wood products and engraving at home, a motor with a power of 150-200 watts is sufficient.

Thus, having a copy-milling machine for wood in your workshop, you can create copies of parts necessary for repairing furniture and other things with your own hands. wooden structures. You can also make souvenir or decorative items according to your own drawings.

Since work on such equipment is quite dusty, it is best to place the machine outside or under a hood

Important! In pursuit of savings, people often forget about the safety of themselves and their loved ones. Please note: working with such a machine is quite dangerous.

Especially in cases where a person has not encountered such a product before.

Conclusion

We hope that the information presented will help you determine the need for this tool. If you are thinking about individual work, then, most likely, the services of an organization working in this direction will cost you easier and cheaper. If there is a desire to put something on the conveyor, then without own machine not enough.

In the video presented in this article you will find additional information on this topic.

Both in production and at home, there is often a need to produce a part whose shape and dimensions are completely identical to the original sample. At enterprises, this problem is solved using a device such as a copy-milling machine, which makes it possible to produce copies of the original part in large batches and is characterized by high speed and the quality of the processing performed.

What is the milling process?

Copy-milling machines and any other equipment of the milling group can be found on almost any industrial enterprise. This is explained by the fact that the milling operation is one of the most common methods used to perform machining. This technology allows you to perform a wide range of roughing, semi-finishing and finishing operations with simple and shaped workpieces made of ferrous and non-ferrous metals, and to work on wood and plastic. Modern milling equipment can process parts of even the most complex shapes with high precision and productivity.

There are two main types of milling: counter (feed and rotation of the tool are in different directions) and down milling (the tool rotates in the same direction as the feed). The cutting part of tools performing milling is made of various materials, which makes it possible not only to successfully work on wood, but also to process (including grinding) even the hardest metals and alloys, artificial and natural stone.

Milling equipment is divided into two types: general purpose and specialized, which includes a copy-milling machine.

Capabilities of copy-milling equipment

Copying machine, belonging to the milling group, is designed for copy-milling work with flat and three-dimensional parts. In addition, such a device can be used to engrave shaped profiles, apply inscriptions and patterns (even of high complexity) to products, and carry out light milling operations on wood and other materials.

Using tools with cutting parts made of various materials, parts made of cast iron are processed on copy milling machines, different varieties steel and non-ferrous metals. Such devices for producing parts in small and large batches successfully produce blades for turbojet engines and steam turbines, propellers for ships, cutting and forging dies, impellers for hydraulic turbines, molds for pressing and casting, molds, etc.

A copy-milling machine performs technological operations that are practically inaccessible to universal equipment. The operating principle of such a machine is based on the copying method, for which a special template is used. The use of a template eliminates the human factor when processing even the most complex parts, due to which all finished products have the same shape and geometric dimensions. Conveniently, one template can be used to accurately manufacture a large batch of parts that will be completely identical to each other.

In order to copy the shape and dimensions of the template as accurately as possible, a copier (pantograph for a router) is installed on a copy-milling machine. The purpose of such a device is to accurately transfer all movements from the copy head to the cutting tool.

How does a copy milling machine work?

Copy-milling machines, as mentioned above, are used for planar (processing of profiles) and volumetric (processing of reliefs) milling. They use cutters as a working tool, which, when processing the contour or volumetric surface of a part, repeat the movements of the copier. The connection between the working element and the tracking system in manual machines is ensured by mechanical, pneumatic or hydraulic elements necessary to generate the force transmitted from the copier to the working element of the copy-milling machine.

The template on such machines is a flat contour or spatial model, a standard part or contour drawings, and the element that reads the shape and dimensions of the template is a copying finger or roller, a special probe, or a photocell. To make a template you can use aluminum sheet or other metal sheet, plastic or wood. The template and the workpiece are located on the rotating work table of the machine.

The working body of copy-milling equipment comes into motion thanks to such structural elements, such as a screw, spool valve, solenoid, differential or magnetic clutch. Relays installed in the amplification devices of copy-milling machines can be electromagnetic, hydraulic or electro-optical.

The quality of the workpiece (surface roughness, accuracy of shape and size) depends on such a parameter as the speed of movement of the tracking device. In this case, the following characteristics of the finished product can be achieved: roughness – No. 6, profile accuracy – 0.02 mm. The main elements of the executive circuit of such equipment are an electric motor and a hydraulic cylinder.

A pantograph installed on copy-milling equipment ensures copying at a given scale. The pantograph structure consists of a guide pin, its axis, a tool spindle and a separate axis of rotation. The spindle and guide pin are located on the same rail, the ratio of the arms of which determines the copying scale.

Moving along the contour of the template, the finger sets in motion the rack, which rotates freely on an axis. Accordingly, on the other side of the rack, the machine spindle makes identical movements, processing the workpiece. On do-it-yourself copy-milling machines, such a device will also not be superfluous; its presence significantly increases the functionality of the equipment.

Types of copy-milling machines

The equipment of a copy-milling machine may include drives various types. Based on this parameter, the following are distinguished:

equipment with a pantograph (suitable for processing parts in 2–3 dimensions);
devices with a copier mounted on a rotary rack moving in a vertical plane;
single and multi-spindle machines equipped with rotary tables round or rectangular shape;
machines, the feed on which is ensured by mechanical, electrical, hydraulic devices;
photocopying equipment.

A homemade copying machine can be any of these types (including copying and grinding machines). You just need to find drawings on the Internet and select components.

According to the degree of automation and the method of fixing the workpiece, the following categories of copy-milling machines are distinguished:

manual or tabletop, on which the workpiece is fixed mechanically(on these devices you can drill holes various shapes according to the template);
automatic equipment of a stationary type, the workpieces on which are fixed using pneumatic clamps (such machines work with aluminum);
automatic equipment of a stationary type with pneumatic clamps, on which a three-spindle head is installed (on these copy-milling machines, triple holes are simultaneously drilled, which does not allow the production of units of the two previous types).

How does a copy milling machine work?

As noted above, on a copy-milling machine the workpiece is processed using a master device - a copier. All movements of the copier along the contour or surface of the template are transmitted thanks to a special (copying) device to the working head of the machine in which the cutter is fixed. Thus, cutting tool exactly repeats all the movements made by the copier used to equip the router.

The movements of the elements of a copy-milling machine during the processing of a part are divided into main (rotation and movement of the spindle when cutting the tool into the workpiece material, movement along the contour of the work table and slide) and auxiliary (movement of the spindle head, slide and table in accelerated mode, as well as installation movements made by the tracer table, the copying finger, the stops and the clamp that secures the spindle head).

In copy milling machines working on aluminum, two tracking schemes can be implemented: simple action and action with feedback. When implementing the direct action scheme, the working body of the machine makes movements due to the fact that it is rigidly connected to the copier. The reverse action scheme does not provide for such a connection and movements from the copier to the working element are transmitted not directly, but through a tracking system.

As mentioned above, contour and volumetric milling is performed on copy milling machines. When contour milling, the movements of the copier occur in a plane parallel or perpendicular to the axis of the tool. In the first case, the movement of the equipment working table can only be longitudinal, and the cutter and copying finger move vertically. In the second case, the table moves both longitudinally and transversely. In volumetric milling, the part is processed in stages - thanks to several movements of the table and tool performed in parallel planes.

The direct action scheme can also be implemented through a pantograph, which allows you to reduce the size finished products relative to the size of the template used (scale). Most often, such an additional device, which is easy to make yourself, is installed on machines used for engraving and light milling work.

How to make a copy milling machine with your own hands

Many home craftsmen would like to purchase a copy-milling machine to equip their workshop, but the cost of such equipment is quite high. Meanwhile, if you have the desire, and without spending a lot of time, effort and financial resources, you can make such equipment with your own hands.

Naturally, homemade copy-milling equipment cannot be compared with professional ones in terms of power, reliability and functionality, but such machines can also make high-quality copies, work with wood and process workpieces from other materials. Many people try to attach a copying device to an existing one, but this is impractical, since it would require redoing almost the entire machine. As practice shows, it is better to assemble your homemade copy-milling machine from scratch, selecting the appropriate components for this.

The photo below shows an example homemade machine with a video supplement. The creator of the machine narrates the story in English, but in principle everything is quite clear even without translation.

The easiest way to make a copy-milling device with your own hands is by standard scheme, which includes a supporting structure - frame, desktop and milling head. The drive to ensure rotation of the working tool is an electric motor that transmits movement through a two-stage mechanism, allowing two speeds to be obtained. Desktop of this homemade device can be adjusted in height.

Many of those who have made a copy-milling machine with their own hands note that when changing operating modes, such equipment begins to show a lot of shortcomings. The most common of these shortcomings are vibrations of the machine frame, curvature of the workpiece and its deflection, poor-quality copying, etc. To avoid such problems, it is best to make the copy-milling device highly specialized and immediately configure it to process workpieces of the same type. This is explained by the fact that it is almost impossible to take into account all the shortcomings that will arise in universal equipment when changing operating modes.
