How to cut straight with a jigsaw? Expert advice. Smooth sawing of material with a jigsaw How to make an even cut with a jigsaw

Without any exaggeration, such a tool as a jigsaw is indispensable assistant in every house. With the help of such a tool, you can easily cut out a wide variety of shapes from a wide variety of materials. It is the jigsaw that is one of the most handy tools for cutting circles, ovals and other complex shapes.

So how to cut with a jigsaw correctly and evenly? You must follow the instructions, and for this you will need:

• protective glasses;
• machine oil;
• gloves;
• jigsaw.

In order to cut smoothly with an electric jigsaw, you must proceed as follows:

1. Before starting work, it is necessary to strengthen the material with maximum strength. It is strongly not recommended to cut along the fibers, since in this case it is very difficult to achieve evenness. In this regard, it is best to use circular saw, in the absence of such a tool, you can use the parallel stop. Such a parallel stop should be attached to the jigsaw with one end, and the other end should rest against the edge of the workpiece. In this way, the most even cut is made.
2. If it is necessary to make a cut inside the workpiece, then a hole is first made in the circle. Then, insert a jigsaw into the hole made and start moving in the direction of marking. After the desired hole has been cut, the corners of the workpiece are easily corrected on both sides.
3. In order to cut with a jigsaw correctly, you should not use force when pressing the tool. Otherwise, the blade will heat up quickly, which may lead to breakage. Do not use one file for a long time, as it becomes dull rather quickly. And such a file makes scuffs at the edges of the material, which significantly impairs the quality of work. If we are talking about cutting materials of increased hardness, then the blade must be lubricated with a small amount of machine oil. Thus, it will be easier to work with a file, in addition, the life of the file will be significantly extended.
4. When working with a jigsaw at low speeds, the jigsaw needs a break, since in such a process the engine often overheats. In this case, it is necessary to strictly observe safety precautions, the presence of goggles and gloves is simply necessary. After the work is completed, the tool must be cleaned and lubricated.

Process features

An electric jigsaw comes with a pendulum and a regular stroke. When the stroke is normal, the blade must be moved vertically, while the material is cut when moving up. The speed of work is quite high, the blade wears out much less.

As for working with a pendulum jigsaw, the principle of operation is the same, but keep in mind that it is best to work with soft wood and plastic, but it is better to refuse cutting steel sheets with such a tool.

If you need to cut a round hole, then an initial hole is drilled in the workpiece, then a file must be inserted there.

Then you should cut along the mark. If you want to make a hole in the form of a square or rectangle, then you need to cut in a straight line. Then the cut out area is removed and the remaining parts, which are in the shape of a triangle, are cut out.

If it is not possible to make an initial hole in the workpiece, it is advisable to make plunge sawing. In this case, the electric jigsaw leans forward until the file reaches the workpiece. Thus, the file makes a through-type hole in the workpiece. Using a jigsaw, you can cut bevels.

When working with a jigsaw, it is necessary that the table is stable, the material is securely fixed and the correct saw is selected.

Sawing with a jigsaw so that everything is smooth is not at all difficult. A guide is fixed on the tool, which is then wound up behind the edge of the workpiece.

If everything is done in this way, then the movements of the file are carried out smoothly and without much effort. In the event that the edge is curved, it is necessary to cut out according to the markup, which must be done before.

If you need to cut a sheet of wood that has a small thickness, chips may appear. In order to prevent this phenomenon, the workpiece should be located front side down.

How to cut straight with a jigsaw? This question interests many, especially at the moment when a person is engaged in construction. This tool helps to cope with a difficult task. But what is it? According to external data and the main purpose, it is comparable to a saw that has an electric drive. At the same time, it is possible to cut various materials:

1. Wood products.
2. Metal constructions.
3. Plastic.
4. Tiles.

And to make the work of any purpose is not so difficult. According to the masters, the main thing is to create all the conditions to make it convenient to work. How to cut straight with a jigsaw? The first is to use only a flat and stable surface. The material to be cut must be firmly fixed, and a saw of the required sharpness and size must be selected.

Such a saw is considered unique because it can work on almost all materials. In addition, she does not only straight lines. It can be used to create curved cuts. But before you start the process, you should understand which jigsaws cut evenly and with high quality.

Work system

To fully understand the process, you need to prepare everything first. Here's what you need if the work will be done on wood:

1. Any piece of wood.
2. Jigsaw with electric drive.
3. Personal protective equipment - goggles, gloves.
4. Machine oil.

Requirements

The very first thing is to securely and firmly fix the material on which the work will be carried out. It also happens that an error occurs, and the jigsaw starts to cut unevenly. It is worth finding out the reason, otherwise it will not be possible to achieve the desired cut. This is the stability of the table, as well as the reliability of fixing the material. It is not so difficult to make even cuts with such a tool, but if you choose the direction along the fibers, nothing will work. Although people with experience can even cope with such a task.

How to cut straight with a jigsaw? If such a need is required for a person without experience, then the following steps must be performed - this is a parallel emphasis. To do this, on the one hand, fastening to the jigsaw is carried out, and the second side - an emphasis on the edge of the tree. This is how it will turn out to make the cut even and without residue of fibers.

Everyone can recognize the device of this unit in the instructions. When buying, many recommendations are given by managers. Each manufacturer invests instructions, this is no less helpful information and is worth studying. Everything should happen in stages, if questions arise, then they need to be resolved, and not continue to work “at random”.

Making holes

How to cut a hole evenly with a jigsaw, for example? Often these steps are required. In order to install the jigsaw in the center of the future hole, a small hole is made, after which the cutting unit is inserted there. Then they simply pass along the marked line of the circle. A rectangular shape is also performed (namely, you need to move the saw along the side of the rectangle). But the corners smoothly bend around. Next you need to cut out the next side.

Another important point in the work - do not press hard on the jigsaw. This condition is often violated by beginners, which leads to overheating and then to a breakdown. In addition, one saw should not be constantly used, otherwise it will become dull and will cling to the material being cut.

Durable materials are not easy to cut. To make the procedure quick, machine oil is used. They are lubricated in the process, and the work goes quickly. Low speed is another problem with such tools. The problem is that it overheats again. No one ruled out safety precautions, and even at home, do not forget about glasses and gloves.

When all procedures are completed, it is worth wiping the equipment and lubricating with engine oil. On sale there is an installation with a conventional and pendulum stroke. The first option is different in that the movement occurs upwards on any material. In the presence of a pendulum stroke and upward movement, an additional knife is thrown forward. This allows you to increase the process of work and at the same time do not wear out the saw much.

Features of the operation

How to cut straight with a jigsaw? Before starting work, you should find out the whole process, otherwise you will not be able to achieve the desired result. Often, when working with any materials, it is required to create a cut with maximum accuracy. It is a jigsaw with an electric drive that will do the job.

Here's what you need for this:

1. Material for work.
2. Jigsaw.
3. Guiding tools.
4. Clamps.
5. Pencil.
6. Construction roll.

Getting Started

The movement of the cutting blade must occur precisely so that the cut is the desired one. It is good when the frequency of movement is high. For this, a saw of the maximum width is taken (this is suitable for wood). The main thing in this process is the use of a guide. A flat board or rail becomes the main assistant.

Clamps are indispensable. They have a workpiece and a guide. The material to be cut should be placed on a slight elevation. This helps not to rest against the jigsaw. After that, the distance that should be cut off is fixed. For this, a roulette wheel is used. After applying the risks with a pencil. Then, using any ruler, these marks are connected, and a cut line is obtained.

What to do next?

Next, you need to fix the guide in a certain place. Clamps help with this. Fixation is performed from the cutting line. After that, you need to position the electrical device with a saw to the cutting line. Now they press the guide and also fix it, there should be no movement, but you should not press it too hard either.

Then they move to the second side and also fix it. The level of fastening is the maximum, but do not forget that some materials can be pressed through. When the whole process is completed, you need to move on to the first clamp. Do its installation correctly and clamp. Only then can you start doing even cut. Otherwise, you will not be able to do quality work.

Now you can turn on the jigsaw and begin the process itself. The speed is high, the pendulum stroke should be at one. And the tool itself is placed so that the file is on the cut line. Only after this, the work will be done with high quality, and the line itself will turn out to be smooth and impeccable.

Do not forget a single moment - if a person has no experience, then any mistake becomes fatal. Especially when you need to cut parts, the number of which is limited. Experts recommend learning how to perform all actions on any unnecessary material and only after that proceed to the main work.

What else do you need to know?

Any device has accessories. They allow the whole process to be made more precise and to simplify something. It is believed that sawing plywood with a jigsaw is the easiest process, since the material does not have a large thickness. Sometimes you need to cut small parts. How to cut plywood with a jigsaw? This will be simplified by having a special table. It mostly comes with this electric tool, although many build it after purchasing it themselves.

The use of a clamp is always necessary. The same applies to the table - it is fixed using such an installation. But the cutting process takes place in reverse side. But the movement is produced not by electrical equipment, but by a detail. Experts believe that this way the lines are accurate and correct.

Many beginners may encounter such a problem as clamping the saw. But how to deal with it? Often, many use a replaceable plate. This applies to additional tools. At the same time, the most diverse material is taken to create such a component. And its fixation occurs to the sole of the electrical installation. And already with the use of components such as a guide bar and an adapter, an accurate line is obtained.

Sometimes when sawing, the material starts to heat up, and the process will simply slow down. In such a situation, it will be necessary to cool the material. For this, a simple cold water. It is fixed on the support sole. Often people have a question about how to cut a laminate with a jigsaw evenly. Everyone knows that it is a tree, for this reason the same principle applies to it. In the process of laying a laminate board, it is precisely such a tool that helps to make the process easier.

It is better to cut from the back side, and the smallest saw is taken for this. This helps to avoid deformation along the cut line. It is with metal parts that heat occurs. Here you need a cold liquid, and for a tool - machine oil. To create a cutting line of any shape, the thinnest saw is taken. Another addition is the circle cutter. Before installing it, a hole is made in the center.

Curved saw cut

When creating a curved cut, a problem arises - the material begins to move. Therefore, before starting work, the table is well fixed (and the part itself too).

How to cut chipboard with a jigsaw exactly?

This question interests everyone. It is important to carefully go around the corners, but you can make a circle in the part only after all other cuts are completed. For such work, the main saw is used. She is enough. Do not use force on the tool. The work of such a tool should take place in several stages:

1. When working with hard materials - the use of engine oil and coolant.
2. Working for high speeds, you need to take a rest, otherwise the equipment will overheat and fail.
3. Compliance with safety regulations, the use of gloves and glasses.
4. At the end of the work, the device is wiped and lubricated with oil.

There are also manual units. How to cut correctly and evenly with a manual jigsaw? It's easier because you can stop and make corrections, although many people think the opposite is true. In any case, a jigsaw is considered an indispensable equipment for the home. Because it works on any surface and creates smooth cuts. If possible, then you need to buy it. He will definitely not be superfluous in the economy.

It is very difficult for beginners to understand how to saw with a manual jigsaw, because there are a huge number of nuances. The basics of the work are mastered quite easily and quickly, which allows you to make various elements of decor and furniture. Many people in the USSR were fond of sawing, and for them special plywood blanks, albums with patterns for sawing, and various jigsaw saws were produced for them. So now find everything necessary tools, materials and patterns is not difficult. About what is needed to organize the workplace, what tools and materials are needed and how to work with a jigsaw correctly, will be described below.

Tool Details

A jigsaw is a tool that is designed for curly (curvilinear) cutting of wooden blanks. A manual jigsaw is used to cut various decorative elements, since it is very difficult to perform delicate work with an electric one. The hand tool has a steel frame in the shape of the letter "U", the ends of which have clamps, and at one end there is a handle. Clamps are used to fix the saw blade and allow you to adjust the tension of the saw blade.

The clamps for fixing the blade can rotate, which allows you to change the direction of the cut. This is what allows you to cut almost any complex pattern along complex paths. However, it is worth remembering that the canvas is very thin and can tear, so you always need to have several dozen canvases in stock. At the same time, it is worth remembering that blades can differ in the size of the teeth, sharpening of the teeth, etc. On this moment There are 2 main types of fabric:

1. Straight. It is a reduced copy of the saw. It is used for straight cuts and often for rough processing.
2. Spiral fabric. It is used for finer processing, surface grinding, etc. This canvas is ideal for making circles and ovals.

Now that you have an idea about the jigsaw, you should start buying all necessary materials and tools.

Preparation of the workplace, tools and materials

The first thing to start with is the selection and acquisition of material for work. For sawing various crafts plywood is usually used, but the blank must meet a number of requirements.

The first thing to consider is the thickness. plywood sheet. For cutting decorative elements hand tool not thick plywood (up to 15mm thick) should be used. It is easy to handle by hand. It is worth noting that optimum thickness a sheet for working with a hand tool is considered 4-6 mm. At the same time, it is worth remembering that the thickness of the plywood blank may vary depending on what decor is planned to be obtained as a result. For example, for making frames for photographs, it is suitable thin plywood, for vases, the average thickness of the workpiece should be used. When working electric jigsaw take thicker sheets.

In addition to the thickness of the plywood sheet, it is necessary to choose the shade and pattern of the veneer. This is necessary if you are planning finishing paint products.

The next important criteria is the moisture content of the workpiece and the sizing of the layers. Only dry plywood is suitable for work. In addition, plywood layers should not separate when processing the workpiece. In addition to the above, it is worth paying attention to appearance blanks. It should not have knots, spots. Plywood with straw impurities is not suitable. Must be firmly glued to plywood and veneer. To determine the quality of gluing layers of plywood and veneer, the following experiment should be carried out: a strip of plywood 1-1.5 cm wide is sawn off with an ordinary hacksaw, if it does not delaminate, then such plywood is suitable for carving with a jigsaw.

Together with the purchase of material for sawing, they also acquire a jigsaw. It is recommended to purchase both a manual jigsaw and an electric jigsaw, as they have different applications. If you have a clear idea of ​​what kind of work will be done (fine or rough finishing in the manufacture of small souvenirs or furniture), then you can purchase a specific tool. For fine workmanship an ordinary manual jigsaw is purchased. When choosing, you should pay attention to the material from which the frame, clamps and handle are made. best material for the frame and clamps - durable steel (possibly stainless steel). The best material for a pen is wood. Such a handle can be shaped over time to fit comfortably in the hand. Should be paid Special attention on clamps. They should be made of steel, not aluminum or silumin.

They allow you to fix the workpiece and avoid its displacement during operation, which will significantly reduce the likelihood of curved cut lines, and also allows you not to break the saw. Next, get carbon paper and sheets with patterns. Using carbon paper, transfer the pattern from the original sheet to the workpiece. If the master has a good eye and artistic education, then he can draw a pattern on the workpiece himself. It is best to use "TM" or "M" pencils for this, they are used to guide the drawing after carbon paper. Workplace equipment will also be required. For creating comfortable conditions work should get a table of 1.5-0.6 meters. This size of the surface will allow you to conveniently position the workpiece of almost any size. It is recommended to purchase an electric burner, which burns out the lines of the pattern. This will simplify the carving process and give a more expensive look to the product (a beautiful black patina is formed along the cutting lines).

But the most important consumable are canvases. Since it is not easy to break a saw when sawing, it is very simple, so you need to have a large supply of files. So, on average, for one workpiece, more or less experienced master consumes about 40 files: 20 regular straight and 20 spiral.

Work process

A jigsaw is cut out on a stand to make it even and easy.

Before using a jigsaw, a pattern should be applied to the workpiece. It can be transferred from a special album (you can look at flea markets for albums with patterns for cutting out the times of the USSR), or draw it yourself. Another option is to print a pattern on a printer and then stick it on the workpiece. Regardless of how the pattern is applied, paint over those areas that should not be cut off. After that, the workpiece is installed on working surface using clamps and yews for fastening. On this preparatory stage work is completed, then proceed to sawing.

Sawing begins with the internal contours of the workpiece. This is due to the fact that plywood is a fragile material, and in the case when the outer contour is cut first, there is a high probability of chipping an already finished pattern. To start working in the internal contours of the workpiece, you should drill holes with a drill into which the file is inserted, after which it is fixed on the jigsaw. If the workpiece has more internal contours that need to be cut out, you should drill required amount holes before fixing the workpiece. This will reduce the operating time. When fixing the blade on the jigsaw, it should be fixed so that there is no vibration of the blade during operation. The cutting process itself differs little from work regular saw- the same progressive movements. An important point when working, it is necessary to maintain an angle of 90 about between the workpiece and the jigsaw saw blade. If the cut is made at an angle, then a rush of the blade is possible. Such mistakes are often made by beginners, but there is nothing wrong with that - the canvas is quickly replaced.

Conclusion on the topic

Despite the fact that the sawing technology is simple, safety precautions must be observed when working, since there is a high probability of cuts or chips getting into the eyes.

Crafts made using this technology will always be original, so you can make a huge number of different decorative and exclusive things - toys, boxes, frames, kitchen utensils, etc.

A jigsaw, along with a drill, a grinder and other tools, is one of the necessary attributes home master. The need to implement the inherent properties in the design causes a reasonable desire for the competent use of the tool. The main requirement is to perform accurate, even cuts of workpieces and parts. Why does it depend? What knowledge is needed?

Performing a technological operation for sawing or creating curly cut involves the formation of a line corresponding to the task. That is, the cut should be even with minimal tolerances for deviation.

These requirements are required:

• Ensuring a tight fit of mating surfaces.
• Create minimal gaps.
• Formation of the correct geometry of the structure from machined parts.
• Attractive appearance of the cutting line and details in general.

Briefly about the tool

A jigsaw is a mini-saw that facilitates the work of a person. The tool processes wood and its derivatives, metal blanks and plastic. The principle of operation is to transfer oscillatory movements to the cutting tool in vertical plane. Moving up and down, in parallel with the translational movement, the jigsaw makes a cut in the semi-finished product.

In addition to vertical reciprocating movements, some power tool models are equipped with a pendulum stroke. Feature - the file moves in a vertical plane and at the same time back and forth. That is, in the working position, the teeth are in contact with the material. In the opposite direction, the file moves back, interrupting the interaction.

Design features

To properly operate a jigsaw is, first of all, to know its device and technical capabilities.

• bed . It is the base on which the rest of the instrument is attached. The platform must be flat, rigid and strong - the correct direction of the file depends on this, and, accordingly, the ability to perform an accurate cut. In addition, the massiveness of the base eliminates the resulting vibration during operation.
• Frame . It combines the main components - the engine, gearbox, saw blade attachment system, controls. It is carried out in two forms - with an arched (staple-shaped) handle or a "mushroom" ("ironing"). Ergonomics, - the convenience of gripping the tool, indirectly affects the performance of operations with minimal tolerances for deviation.
• saw blade attachment mechanism . Reliability of fixation, absence of free movements (backlash), keeping the direction in one plane is one of the technical possibilities for precise sawing.

Useful equipment

The implementation of an even seam is facilitated by a number of devices produced for the jigsaw:

• Compass stop . It will be required for accurate cutting of a circle.
• Parallel side stop . Designed for straight cuts. The straightness of the seam depends on the condition of the lateral (retaining) side.
• Guide bar . Allows you to perform an accurate straight cut at a distance of 20 centimeters or more.
• Platform overlay. Reduces the coefficient of friction, increases sliding on the surface of the workpiece.
• Anti-scalding insert. Reduces the chance of chipping. Useful for processing laminated materials.

Characteristics affecting the accuracy of the cut

The electric jigsaw has certain characteristics that indirectly or directly affect the nature of the cut. For clarity, the indicators are summarized in a table.

Important point , - no matter what the characteristics of the tool, a poor-quality assembly can nullify the capabilities of the device.

Cutting tool

The second most important element of the jigsaw, which affects the accuracy of the cut.

File parameters:

• Blade length . Determines, in addition to power, the thickness of the workpiece. Dimensional mismatch leads to peak operating modes, vibration. The fact of breaking the seam is very likely - an increase in width, the formation of uneven edges.
• Web width . Increasing the size helps to maintain the direction of the cut. Narrow files are convenient for making curved lines.
• Canvas thickness. Increases the rigidity of the cutting attachment, - reduces the likelihood of drift to the side. The perpendicularity of the file to the surface of the workpiece is maintained. The quality of the cut is improved.
• Tooth pitch. Defines the type of material to be processed. Parameter 3~6mm is for rough wood processing. 2 ~ 3 mm - clean cut of the laminate, furniture panels, parquet board. Up to 1 mm - metal processing. For the convenience of the consumer, markings are applied on the side - the inscriptions "wood", "metal", etc.
• Divorce of teeth. Allows you to make a seam size that does not interfere with the movement of the canvas. There is no possibility of jamming, skew.
• Blade material. Affects the strength, rigidity and sharpness of the teeth. The distortion of any parameter affects the quality of the seam.

Files for work on ceramics, glass, polymers are produced. Right choice cutting tool is one of the guarantees of an accurate cut. An additional factor is the sharpness of the teeth. A blunt file does not make a smooth cut.

Processed material

The type of material being processed, its thickness quite strongly affects the quality of processing. The use of wood saws for sawing blanks of pine, larch or oak leads to different results due to the strength properties of wood.

Another example, working with different types steel, stainless steel and black iron. Here there is a difference in strength, toughness, brittleness.

Sawing a workpiece

Work with a semi-finished product consists of several stages:

• Acquaintance with the processed material, its properties.
• Choice of cutting mode, selection of the necessary cutting tool (sawing file), auxiliary equipment.
• Checking the performance of the jigsaw, serviceability individual elements, no play in moving parts.

Sawing a tree

Stages of work:

• The technical capabilities of the jigsaw with the geometric parameters of the workpiece and the material being processed are checked:
• The working stroke - the thickness of the part - the length of the file.
• Type of wood - saw blade thickness - tooth size.
• Tree properties - cutting mode (stroke frequency).
• The need for a pendulum function. For a clean cut, the function is disabled. Speed ​​is important - a pendulum stroke is used, but the accuracy of the cut is reduced.
• The question of the use of additional equipment is being considered. The decision depends on the requirements for the evenness of the cut and the magnitude of the errors.
• being prepared workplace. Main characteristic stands - ensuring strength, rigidity and stability. Another property is the flatness of the table surface.
• The cutting line is marked. If there are no restrictions on the brightness of the line, then it is advisable to use a black marker. In another option, it is advisable to use a pencil - its traces can be wiped with a student's eraser.
• The workpiece is fixed on the table. The main requirement is a strong fixation that limits displacement on all sides. The protruding part, if necessary, is weighted with additional supports. This is necessary to reduce the effect of the mass being cut off on the main part and the file. It is required to ensure the free movement of the cutter in a vertical position.

Sawing wood

A jigsaw connected to the mains is installed on the surface of the workpiece. The front of the platform must be flat against the workpiece. Deviations from these recommendations can lead to shock at the beginning of cutting, increased vibration, and removal of the file from the path.

The “Soft Start” function helps to increase the initial accuracy - the engine slowly picks up speed, the cutting process is carried out in the normal mode. The jigsaw must be moved slowly, without jerking, at low speed. Constantly carry out visual control over the position of the cutting point and marking.

Helps in this process laser ray, illumination of the cut line and blowing - removes chips from the markup. B O Greater cutting accuracy will be provided by tracking the saw itself, more precisely, the place of contact with the workpiece.

1. Thick softwood, over 40~60mm, needs to be cut at the minimum longitudinal feed. Increasing the pressure in this direction will increase the risk of cutting plane curvature - the lower part of the cut will move 1~5 mm to one side. That is, an inclined cut is formed. These recommendations are valid for dense and hard woods, glued products, but with a smaller thickness.
2. Longitudinal sawing (along the fibers) of a tree is advisable to carry out with the pendulum stroke function turned on. In addition to increasing the processing speed, the likelihood of the file moving to the side will decrease, and the accuracy of the cut will increase.
3. The use of auxiliary equipment is not a panacea - you should not completely rely on fixtures. Constant control over the course of the process is required - it is better to have time to interrupt sawing in time than to make an irreparable mistake.
4. It is advisable to use the side stop when the edge of the side of the part is even. You can check with a ruler, a carpenter's square, a rule, a laser level.
5. An increase in cutting resistance is evidence of blunt saw teeth. Another indicator is the strong heating of the cutting tool, a change in color, up to blue-colored shades.

Laminated wood processing

The difference from ordinary wood is the imposition of several layers of additional coating on one or both sides. One of them, from the front, performs strength, protective and decorative functions. For example, laminate parquet board, furniture boards.

The peculiarity of processing is the maximum preservation of the front surface during the sawing process. Fastening requirements are similar to wooden blanks. The nuance is in the location of the part itself, up or down with the front part. It depends on the file, with forward or reverse motion.

Chips on the surface are formed on the side facing the jigsaw in the forward mode - the saw teeth are directed upwards. Correction consists in turning the product "face down". Another option is to use a tool with "downward" incisors. The negative effect is an increase in vibration during processing.

1. The pendulum movement is disabled.
2. Stroke frequency is maximum.
3. File for a clean cut. On the side there is an inscription "clean cut" or "clean".
4. The size of the tooth is not more than 2 mm. It is allowed to use saw blades for metal.

Curvilinear cut

Making curved lines, circles is one of the types of processing, for which, in fact, a jigsaw is needed.

Hole creation:

• A hole is drilled in the body of the workpiece, with a diameter of b O larger than the file size by 2~3mm.
• A cutter is passed inside the freshly made opening.
• The transition to the main line of the cut is carried out along a curved path, - along an arc.

1. The accuracy of the curvilinear cut will be provided by a narrow file, - “a file for a figured cut”.
2. Increasing the accuracy of the cut - the use of "emphasis-compass".
3. Mode: maximum stroke rate, minimum longitudinal feed (movement along the cutting line), pendulum stroke disabled.
4. Surface sawing without reaming:

• The front edge of the sole is set outside the marking at an angle to the plane of the workpiece, approximately 45 ~ 60 degrees.
• Reducing the slope, with a smooth movement bring the file to the surface of the workpiece. Without applying pressure, they crash into the body of the part.
• Bring the sole to the plane without interrupting the cutting process.
• Continue cutting along the required path.

In this way, internal holes are made, with a curvilinear (oval, circle) generatrix or at different angles between adjacent sides (rectangle, rhombus, trapezoid).

Sawing metal

Features - the thickness of the workpiece, depending on the power of the jigsaw and the type of steel, does not exceed 10 ~ 12 mm.

Cutter mode:

• File for metal, - a tooth no more than 1 mm (outwardly it resembles a saw blade of 300 mm for a hacksaw for metal). The inscription is metal (metal).
• Minimum stroke rate.
• The pendulum mechanism is not activated.

1. A thin workpiece (up to 2 ~ 5 mm), in order to increase the accuracy of cutting, reduce vibration, rattle, must be fixed between two sheets of furniture fiberboard. Carry out the marking on the auxiliary surface.
2. Metal, due to increased loads during sawing, must be carefully fixed. Ensure free movement of the saw blade in a vertical position.
3. The long end of the part to be cut is fixed in an additional support.
4. The initial moment of sawing should be very smooth, without a sharp touch of the metal file.
5. The use of lubrication contributes to the increase in accuracy - machine oil is applied in drops along the cut line.
6. It is advisable to cut thick workpieces with breaks for cooling the saw blade and jigsaw.

Sawing tiles

The jigsaw is successfully used for processing tiles or natural stone. Process feature:

• The combination of brittleness and strength of the material.
• Increased hardness and abrasiveness.
• Accelerated cutter wear.
• The pendulum mechanism is disabled.
• Minimum RPM.
• The use of a special file - with applied abrasive material (diamond grit, electrocorundum, etc.).
• Smooth movement along the cut line at low feed.

An electric jigsaw is convenient for making curved cuts on tiles, other methods are complicated and require special equipment.

The requirements for fixing the product are the same as for other materials. It is recommended to apply wetting with water or oil - this improves cutting conditions, increases the accuracy of processing.

Conclusion

So, the terms of the exact cut:

• The presence of a properly adjusted jigsaw.
• Sturdy hard work table.
• Reliable fixation of the workpiece.
• Correct markup.
• Application, if necessary, of additional equipment.
• The confident hand of a master.

The electric jigsaw is the most convenient and universal tool For complex work on wood. It can be used to produce artistic carving, training various parts for carpentry and other tasks.

Operating procedure

To obtain best result work, you need to know how to cut with a jigsaw.

• The material being processed must be securely fastened. Poor workpiece clamping is one of the main causes of sawing errors. The jigsaw can jump off, go off the markup, or even go in an arc. By the way, if the jigsaw cuts crookedly, check if the direction of the cut does not coincide with the direction of the fibers. If this is the case, then it is better to make a cut with a circular saw.
• When it becomes necessary to make a cut on the inside of the workpiece, you should pre-drill a hole at the start of work.
• When working with the tool, do not make great efforts. An electric tool cuts wood quite well and without undue pressure. If you make a serious effort to advance the jigsaw, the saw and motor get very hot, and the risk of breakage increases. Besides, overpressure - main reason chips.
• When cutting hard rock wood, it is advisable to add a little machine oil to the canvas.
• Sometimes you have to work at low speeds. In this case, it is necessary to take frequent breaks in work, as the saw gets very hot.

Problems with accuracy

Consider how to cut with a jigsaw exactly:

1. The object of processing must be securely fixed. Moreover, in such a way that it was convenient to make a cut.
2. In case of particular uncertainty or for a greater guarantee of accuracy, it makes sense to use guides. For straight cuts, you can use wooden block, fixed along the markup. If the shape of the cut is complex, then the situation becomes more complicated. In this case, you can use patterns, if any, or you will have to reduce the speed of work due to more accurate jigsaw guidance.
3. One of the reasons why a jigsaw cuts crooked is problems with the saw. Perhaps it is dull or has chipped teeth. Noticing that the jigsaw literally turns itself where it likes, inspect the saw.
4. Breakage of a jigsaw. For example, if the motor runs jerkily, the likelihood of a crooked cut increases dramatically. Likewise, other failures of the mechanism can lead to a drop in accuracy. Such problems are difficult to fix on the spot, as diagnostics are required, and possibly repairs.
5. Finally, the skill of the performer greatly affects the accuracy of the work. If you are a novice carpenter, do not get upset because of periodic failures: accuracy comes with experience.

chipped

Another serious question is how to cut with an electric jigsaw without chipping? These usually form:

• with excessive pressure on the tool;
• when working on thin material near the edges without reinforcing stops;
• when using unsuitable (worn out) saw blades.

Avoid these actions, and you will reduce the likelihood of chipping to a minimum. Also, some models allow the use of special anti-splinter inserts for a jigsaw.
