Cutting machine with a broach with your own hands. Wood trimming and types of cutting discs. How to adjust the degree of inclination of the cutting head - video

Mostly Miter saw Is the most common circular saw mounted above the table. Due to some features of the tool, it becomes possible to cut with great effect different materials at a specific angle.

This homemade miter saw can cut:

wood;
plastic;
aluminum;
various non-ferrous alloys.

The most important characteristic features miter saws are:

compactness;
light weight.

The weight of the machine can fluctuate and reach a maximum of 30 kg. It all depends on the specific model, its functional capabilities. Miter saws are widely used in the woodworking industry. With their help, you can solve a variety of tasks.

The use of a miter saw allows you to make a "mustache" connection. Such machines are called "trimming and trimming". This tool is widely used by masters of baguette workshops, it is also used in the production of furniture.

Miter saws allow you to cut parts made from a wide variety of materials. The cut-off models use replaceable discs that allow you to cut the appropriate type of material. Almost all types of miter saws are made in such a way that it was possible to set the tool at a specific angle and a specific size by rotating the table.

On some saw models, it is possible to rotate the tool only in a certain direction. Usually the cost of such a saw is quite low. When the saw can be rotated in different directions, the machine has many added benefits. However, the cost of such a device is very high.

The saw can be swiveled through 360 ° to machine workpieces of any complex shape... The saw head is tilted relative to the work table. It is quite easy to adjust the saw blade rotation.

Every master who has conceived to perform homemade trimming should take this into account the most important moment... To determine the required angle of rotation, he must determine what materials and workpieces will be cut by the miter saw.

Rotation of the saw through an angle in the range of 45-55 ° is considered normalized.

Making and assembling a do-it-yourself miter saw

To make a bed, you need a thick a metal sheet and steel corners. An old bed is perfect for this purpose.

With help welding machine a hole is made in the steel sheet, the edges are finished with a file.

For work will do low power electric motor. 900 watts is enough. It is mounted on a base using an additional spring. It plays the role of a stabilizer.

Such a design requires some effort to tilt the system. To move the handle, you have to apply significant forces. The result is a smooth movement of the saw unit.

Device parameters:

radius cutting disc- 100 mm;
spindle speed - 1500 rpm.

These characteristics make it easy to handle wood with a maximum thickness of 70 mm.

If there is no bed at hand, the bed can be welded from metal corners.

Adjustable feet and legs should be provided. The basis of the pendulum rack is a channel, which rests on a metal base.

As a result, the installation gets additional strength, its weight is added. On such a machine, it is very easy to perform homemade trimming.

For work, you can use three-phase electric motor, with a power of 2 200 watts. As a support, a swinging plate is mounted, which is held by the hinge joints. The pulley belt of the electric motor is tensioned by a folding device. The pendulum is made from the material that was used for the frame.

Saws with a diameter of 420 mm are suitable for work. The number of spindle revolutions must be at least 2800 rpm. With such parameters, you can process wooden blocks 70 mm wide.

Miter saw advantages

First of all, this applies to small financial investments... The cost of all components is quite affordable for every craftsman. Thanks to the high savings, an original and multifunctional cross-cut saw is obtained. However, such high savings can only come about if each component can be purchased very quickly.

For example, no electric motor certain power may affect the economy of the entire structure.

The advantages of such a homemade miter saw can be attributed to the fact that it fully meets the needs of the manufacturer. He can select the desired parameter of the machine, make a table of the appropriate size, set the saw rotation speed.

Of course, the advantage of such a machine is the master's knowledge of all the details and assemblies of the trimming device. He will be able to fix the breakdown very quickly, to carry out the necessary repairs. Such a homemade trimming can be considered a real competitor to factory counterparts.

The trimmer design is similar to a circular saw mounted above a work table. Its main advantages are compactness and low weight. Thanks to this, saws are used not only in workshops, but also in construction sites... Unfortunately, DIY tools are quite cumbersome and heavy. It is convenient to operate them in a stationary mode.

The miter saw is designed for a single task - trimming the ends of lumber at different angles. Due to the fact that the workpiece is stationary on the table during cutting, the cut is neat and clean. Craftsmen dealing with woodworking give preference to this particular tool. Moreover, hand-made saws have been successfully used for years.

Trimming from a grinder

Technical characteristics of cross-cut with a broach, assembled by hand:

disk revolutions - 4500;
cutting length - 350 mm (much higher than that of a factory tool of the middle class).

The tool can be removed from the table and the grinder can be used for its usual purpose.

Manufacturing details:

The rotary device of the tool is installed on the pivot of the car wheel (kingpin), it is held by a ball bearing for 150 mm (if you can find more, it will do).
We attach the ears to the outer side of the bearing by welding to fix it on the base. It is fixed by means of M6 screws.
To protect against shavings, the holder is covered with a box.
We make the broach from the shock absorbers from the truck (broken ones will do). Oil is poured out of them, holes for ventilation are drilled, which should be tightened with a mesh from dust and chips.
So that at the beginning of work there is no jerk, the saw is supplemented with a module smooth start, which slightly reduces the revs.
The last stage of work is the manufacture of protection for the disc.

Cons of the design:

works very noisy;
to adjust the accuracy of cuts in wood, trimming of bars is used, after which the thrust is fixed rigidly and you can work clean.

Trimming from various scrap metal

This is a rather heavy bevelling on a stationary metal table... It will take some effort to manage it. But in the end, the saw mechanism moves smoothly, without jerking, do-it-yourself trimming is easy.

Specifications:

electric motor power - 2.2 kW;
disk revolutions - 2800;
cutting depth 80 mm.

Materials and tools required for assembly:

900 W electric motor;
a metal sheet;
metal corner;
channel;
hinge group;
powerful spring;
Bulgarian;
welding machine;
file.

The bed is made of adjustable supports, metal corner and racks from old bed... The working surface is a metal sheet like the surface of the table, in which we cut a hole, we process the edges with a file with our own hands.

The pendulum saw stand is welded from a channel mounted on a sheet of metal, its height is about 80 cm.
The support for the electric motor is made in the form of a movable metal plate mounted on hinges. When installing an electric motor, a spring is used as a stabilizer. Then you can do without the pendulum and belts.
The tension belts are adjusted with a conventional eye bolt, the swingarm for the mechanism is also made of metal.
A 420 mm diameter disc is installed on the facetting as an executive tool.

A miter saw is a rather dangerous equipment, collecting it with your own hands, you need to take care of protective boxes and covers. After all, errors in work homemade equipment much more than the factory one.

Advantages and disadvantages of homemade trimming

Benefits:

Making a tool with your own hands saves money. For example, about 500 rubles were spent on the revision of the grinder. The cost homemade table and the saw mechanism is available to most craftsmen;
basic parameters: cutting depth, rotation frequency, disc diameter, engine power, table dimensions, are selected according to their own needs;
having assembled the tool with his own hands, the master will easily find the cause of the malfunction and eliminate it.

Disadvantages:

The service life of the tool depends on the quality of the raw materials, and homemade products are usually collected from all sorts of trash;
trimming homemade are rarely powerful enough. Indeed, for the high-quality operation of the equipment, a careful selection of parts is required;
sometimes the funds saved on the purchase of a factory tool are spent on repairs and revision of a homemade one;
craftsmen often save on their safety by not equipping the table and saw with protective devices;
Factory saws are equipped with a graduated scale that accurately indicates the cutting angle of the tree. It is difficult to build such a mechanism on a home device.

A few more convenient and interesting homemade products, including an excellent stationary, mobile and made in a couple of minutes from several plywood and screws:

A wide variety of equipment can be used for wood processing. Similar material lends itself to processing, which determined its popularity in the production of various things. A cross-cut machine is used to change the size and shape of the workpieces. Its design is similar to that of circular saw however, there are several differences that determine the popularity of the machine. The main advantages include low weight and dimensions, which allows the equipment to be installed in a home workshop. You can make a do-it-yourself wood miter saw, but as a rule, homemade products will be more cumbersome and less productive. It is convenient to operate this equipment in a stationary mode.

The purpose of the trimming machine

Unlike a circular saw, the miter saw in question can be used exclusively for trimming the ends various lumber... Some models allow you to maintain a certain angle. In the case under consideration, trimming takes place when the workpiece is stationary, which determines a better cut. This moment determines the fact that a homemade miter saw in workshops is quite common, since only when using it can you make a clean, even end. Self-made saws can serve for several years without major repairs.

Trimming on the basis of a grinder

To solve the problem, a grinder is often used. It is ideal for making your own end-face miter saw. Homemade option execution will have the following technical characteristics:

the revolutions of the grinder's disk should not be less than 4500 revolutions per minute;
the cutting length is 350 millimeters. Note that this indicator is significantly higher than that of a factory instrument, which belongs to the middle class.

The created design allows you to remove the grinder from the table and use it as a regular tool.

When considering how to make such an execution option, we note the following points:

The last step in production is the creation of the saw blade. This element eliminates the likelihood of foreign bodies entering the cutting zone. Your own miter saw can be used at home.

However, the design under consideration also has significant drawbacks that should be taken into account. These include:

DIY miter saw is very noisy. This is due to the peculiarities of the grinder. During processing, noise appears, which is almost impossible to reduce;
the cross-cut machine is used for high-quality processing of end surfaces. That is why quite a lot of attention is paid to the accuracy of the positioning of the grinder with the disc relative to the workpiece. To adjust the location of the grinder with a disc, trimming bars are used. The rod should be fixed with a bolt, after which processing can be carried out.

Blueprints trimming machine determine that it can be installed quite simply in almost any workshop. It should be borne in mind that the moment that the structure has small size, and the workpiece can be quite large. In order to eliminate the likelihood of loss of accuracy during processing, the structure should be fastened to the base.

Special attention is paid to the type installed disk... Initially, the grinder was designed for metal processing, which determines the presence a large number discs for metal. But there are also discs for wood processing, which have their own characteristics.

In conclusion, we note that there are quite a few drawings that can be used to create a miter saw. Some are quite simple to implement, others are difficult to implement.

The miter saw is created by hand on the basis of the existing equipment - manual circular saw, angle grinder (grinder). And when mounting discs of a specific type homemade device can be used for cutting a profile on a metal-plastic base, pipes, which will increase the area of its use.

Varieties

Cross-sections are divided into the following types:

pendulum;
combined;
with a broach.

The base of the pendulum device is the frame. A table is also attached to it, which is based on a rotation mechanism with a ruler. This mechanism solves the problem of setting the cutting angle with its adjustment. The cutting angle can be adjusted by moving the table in relation to the base surface. The saw component is held in place by a handle and is spring-loaded with a hinge. The pendulum moves the saw vertically.

In the combined modification, it is possible to change the cutting angle in two directions. The structure is the same as that of the pendulum facing, only one more hinge is added. As for changing the cutting angle in the horizontal surface, it can be changed in the horizontal direction, which is also opposite to the installed drive.

Crosscut with a broach allows you to translate the cutting component both along the circumference of the hinge axis, and directly along the length of the cut. This is obtained due to the existing guides.

Tool creation

It is possible to make a miter saw with your own hands, taking the available equipment as a basis.

From a hand-held circular saw

The structure is common and acceptable for home construction. The body of the trimming unit is made of wood or iron. Of plywood sheets(Chipboard) build a base on which to mount upright rack, having previously cut holes in it to fix the facing. A pendulum-type device is made from a board and is attached to the base by means of a long bolt.

Having prepared a steel rod or corner, it is attached on top of the pendulum so that the end sticks out. Then the spring is taken, with one end it is fixed to the rear shelf of the corner, and the other - to the vertical rack. The tension is selected empirically, but it should be enough to easily hold the circular saw in the hanging position.

Having removed the handle from the equipment, it is fixed on the pendulum in a previously prepared hole. The wires are placed in the slots prepared for this, and the power supply is connected. A small slot is made in the table top, and side stops are fixed to it at an angle of 90 °. If they are made rotatable, then it will be possible to cut the blanks at a specific degree. The unit is assembled, it remains to test it in operation. Using drawings, you can make anything, even a very complicated apparatus.

From the grinder

Miter saws are capable of cutting wood, iron, plastic and other materials.

The most famous facing is based on the use of an angle grinder.

If you manage to do everything correctly, your device with a broach will have the following options:

disk rotation speed - 4500 rpm;
cutting distance - about 350 millimeters.

If necessary, trimming is dismantled from the unit and is practiced as usual hand tool... A big plus is that the self-made device is versatile and freely disassembled.

Let's consider how the manufacturing procedure takes place.

Put swivel mechanism angle grinder on the axis of rotation of the wheel of the unit. Its fastening is made by means of a ball bearing. The recommended size is 150 millimeters, but larger ones will also work.
FROM outside the bearing is electrically welded to the ears. They are designed to secure the base of the unit. Install with M6 bolts.
The holder should be covered with a protective cover so that chips do not fly on you during operation.
The broaching problem finds a solution simply. To create it, take shock absorbers from truck... Even if they are not in working order, this is not a problem. Remove from shock absorbers lubricant, drill holes for ventilation and cover with a mesh to prevent chips and dust from entering the cavity.
Install the soft start module. Thanks to it, you will not experience sudden jerks when starting the trimming.
The final stage is the installation of protection saw blade.

Depending on the supplied disc, the unit can be used for metal or wood, for trimming pipes. But be aware that the power of the unit may not be enough to cut the ends of the pipes. Decide on the specifications of your angle grinder to find out if the machine is capable of cutting pipes, or if it is only suitable for working with wood.

This design has two important drawbacks.

To adjust the precision of the cut, wood residues are used first. Then the traction is fixed, and you can get to work.
The unit makes a lot of noise when cutting pipes and working on iron.

Manufacturing a complex unit

There is an option with a more complex and heavier design. She will definitely handle facing metal pipes... At the same time, a self-made device does not require the use of a circular as an element of the unit. But for specific moments of work, it is better to keep the circular at hand.

Based on the selected components, you have the opportunity to make a unit high power. To create it you will need:

an electric motor with a resource of about 900 W, and if you need constant cutting of pipes, you can take a more powerful electric motor;
sheet iron;
metal corners;
channel;
hinge groups;
angle grinder;
welding machine;
file;
powerful spring.

When everything you need is ready, you can start assembling the end machine.

The bed can be made using customizable supports, metal corners and bed racks.
As work surface a sheet of strong iron is used. It is necessary to make holes in it and file them with a file.
For the manufacture of the pendulum rack, we use a channel and a welding machine. The structure is placed on an iron sheet. Approximate stand height 80 cm.
The base for the electric motor is made of iron sheet in the role of a stationary plate. The bed is necessarily mounted on hinges.
A powerful spring will serve as a stabilizer for the electric motor of the miter saw. If you find one, then you can refuse from the swingarm and belts.
The lifting bolt can be used to tension and adjust the belts. The pendulum can be made of steel so that the structure is strong and reliable.
The cutting tool will be a disc of the required diameter. For household tasks, as a rule, a saw blade with a diameter of 400-420 millimeters is enough.

The presence of a miter saw in the arsenal of a summer resident greatly simplifies life. This type of saw can be found in any building supermarket, but the price of a branded crosscut saw will cause huge damage to the family budget.

In order not to overpay, you can assemble a miter saw with a broach from improvised material and old tools available to almost every self-respecting man. In this article, we will go over the process of assembling a homemade miter saw and find out exactly what tools you may need to do this.

Characteristics of a homemade miter saw:
✓ 350 mm cut length;
✓ 4.5 thousand rpm;
✓ relatively low weight.

The advantages of a homemade miter saw

Since the design is based on an ordinary grinder, it can be removed and used in work with other material. Homemade machine, unlike its factory counterpart, is completely universal, largely due to its low weight and the possibility of complete disassembly. Another advantage of such a saw is the relatively inexpensive assembly cost: no more than 500 rubles are spent on everything (not counting the cost of a used grinder).

Disadvantages of a homemade miter saw

Difficulties in selecting the accuracy of cuts
For the best possible result, you will have to make several rough passes, then fix the thrust and make a fine saw.

Noise
Due to the fact that the saw is based on a noisy grinder, the unit will give out a lot of noise. This deficiency can be corrected with the help of a more modern apparatus.

The nuances of assembling the construction of a homemade miter saw

The upper pivot part of the unit is mounted on a king pin with the largest bearing on the market. Lugs are attached to the 150 mm bearing from the outside, through which the unit is attached to the working surface using standard M6 screws. The clip is protected from debris by a specially made partition.

It is recommended to use shock absorbers from the front struts as a broach. passenger car which are used in many cars, for example, in the VAZ 2108-15, and the shock absorbers from the truck will make the structure too massive and overwhelming. You can buy them at almost every scrap metal collection point. Before installation, disassemble the shock absorbers, drain the oil, make "air" holes and cover them with residual cloth.

For more comfortable work with a saw, a soft start system should be adapted to the grinder, because without it the starting jerk will be too strong. Moreover, the installation of the block contributes to the reduction and regulation of the number of revolutions. To increase safety, additional protection is attached to the grinder and the bed.
