Do-it-yourself edge trimming machine drawings. Applications and types of edge trimming machines: double-saw or single-saw

Any wood processing enterprise, from small to large, faces the problem of a large amount of waste when processing logs. The sawmill makes a rough cut of the log, cutting it to a square beam, and then, if necessary, dissolving it into bars or edged board required sizes. It is not rational to process rounded waste on a sawmill.

However, this waste can bring a lot of benefits and additional profit. Edged boards of small thickness, glazing beads and many other useful products are made from them. It is for this purpose that an edge trimming machine is installed at every woodworking enterprise.

1 Application and operating principle

Each woodworking enterprise tries to reduce production waste to a minimum and use wood as rationally as possible. These tasks can be accomplished edge trimming machines.

Most often, domestically produced equipment is installed on sawmills, such as TsOD 450, Taiga, Kedr, etc. IN living conditions often use machines made with their own hands from scrap materials.

This equipment allows you to trim the rounded edges of shalevki and slabs and get an edged board. The edge trimming machine also allows you to cut boards into bars and blanks with a thickness of 5 mm or more. Such products are in great demand, because they are used in construction and decoration.

1.1 Design features

It is quite difficult to unambiguously describe the design features of wood cutting machines, since edge trimming machines have a large number of classifications.

According to the method of powering the engine, the equipment can be:

electrical;
liquid fuel

The sawing unit can move along the guides manually or automatically using an electric drive.

According to the number of saws, an edge trimmer can be:

single saw. Allows you to make one cut in one pass. To trim the second side, the workpiece must be rotated;
two-saw. In one pass, the board is cut on both sides. On the domestic market they are represented by the models Data Center 450, Taiga K2M and many others;
multi-saw One pass of material work surface allows you to immediately cut the shalevka into bars or boards of the required size.

Any machine consists of a bed on which workpieces and carriages are placed with a motor that rotates the circular saws. It can cut workpieces of any length and width, which greatly simplifies work and reduces the amount of production waste.

1.2 Operating principle

IN general outline Any edge trimming unit for wood such as TsOD 450, Taiga and others - single-saw, double-saw or multi-saw - works the same. Fits on the frame wooden blank, along which one or more circular saws. The carriage on which the saws rotate moved manually by the machine operator for special handrails.

The DPC 450 single saw requires two passes to cut edges on both sides. As a rule, such equipment is designed in such a way that trimming can be done by moving the carriage in both directions.

A two-saw machine, the circular saws on which rotate in different directions, cuts on both sides at once, thereby significantly increasing labor productivity.

Multi-saw edge trimming machines are designed for sawing wood blanks into bars or boards of the required size. This unit can simultaneously operate up to 14 circular saws in parallel.

A two-saw and multi-saw edger such as TsOD 450 or Taiga requires adjustment of the distance between the saws. This process on older models is performed mechanically, with your own hands.

New sawing machines for wood are equipped with electronic control, allowing you to automatically arrange the saws in the desired position accurate to the millimeter. In addition, new models such as Data Center 450 or Taiga are equipped with a laser ruler for setting workpieces and switching saw rotation speeds.

1.3 How does an edge trimmer work? (video)

2 Common models and manufacturers

On the domestic market you can find edge trimming machines of various modifications of domestic production. This is due to both the cost and quality of the units. Foreign models are less common, but they are much more expensive.

Among single saw machines for wood the most popular brands are “Cedar” and “Taiga”.

The two-saw machine is represented by the models TsOD 450, Taiga K2M, Avangard, etc.

Most wide choose, both among domestic and among foreign manufacturers, multi-rip machines.

TO domestic production multi-saw units include:

Taiga SDM-1;
Aster;
Vanguard;
Stiletto and others.

Foreign manufacturers offer the following models:

MS Maschinenbau (Germany);
Wood-Mizer HR1000 (Germany), etc.

2.1 Making a machine with your own hands

It is very difficult to make a two-saw unit with your own hands. And it’s unlikely to be needed for domestic purposes. Therefore, let's look at it step by step, how to make a single saw edger on wood with your own hands.

Let us note right away that the production of such a unit will be quite expensive. But if you have a lot lying around in your home unnecessary products made of metal, old engines and other things, then it is quite possible to take on such work.

To make an edge trimmer we will need:

Metal pipes, channels and angles.
Electric motor.
Shafts, for example, from agricultural machinery.
Circular Saw.
Tools for working with metal (grinder, drill, welding machine).
Connecting elements (bolts, nuts, couplers).

2.2 Stages of work

First you need to make a strong, reliable, stable frame with your own hands. A poor-quality bed leads to vibrations, which, in turn, causes crooked cuts and damage to the saw. Suitable for making a desktop metal channels.

We will make a frame with parameters 6500×2500 mm and a height of 1000 mm with our own hands. To do this, we need to weld a frame from channels and weld the legs to it.

Using the letter “P” we weld metal channels to create a carriage and weld a crossbar on which the saw will move.

We install the engine. His choice must be approached especially responsibly. When using a circular saw with a diameter of 250 mm, we will need a motor capable of providing a rotation speed of at least 5000 rpm.

We attach the motor to the bed so that it rotates the saw parallel to the longitudinal edges of the bed.

All welded and bolted connections must be made with your own hands as reliably as possible. Do not forget that the rotation speed is high, and, therefore, the likelihood of serious injury is also high.

The production of lumber from logs is accompanied by the formation of rounded waste. On large equipment with a circular saw, process them into products suitable for further use will not work. For such needs, it is advisable to have a through-type edge trimmer with one or more saws. You can get your own assortment of building blanks with a thickness of 0.5 cm and higher: bars, thin edged boards, laths, lamellas, glazing beads.

Various solutions in machine design

Depending on the intended purpose and installation location, an edge-edging woodworking machine can combine the following design solutions:

engine internal combustion or electric;
carriage with cutting elements driven automatically/manually;
number of saws making simultaneous cuts (1, 2, 3...).

Common to the edge trimming machine are a frame with guides for moving the carriage, clamps - clamps for the workpiece, a control unit, and optionally - a laser ruler, which simplifies positioning operations.

Models for industrial production differ automatic device feeding wood under a stationary carriage. They are equipped with systems for removing sawdust, dust, and waste.

Features of work

If a single-saw unit is installed on the edge trimming machine, then cut one side of the board first, and the other in reverse. This option is suitable for small processing volumes. A multi-saw edge trimming machine, which, if necessary, has up to 14 simultaneously operating saws, can reduce time and costs. The cutting is performed in 1 pass of the carriage.

Circular saws on the Taiga edge trimmer are installed with rotation in opposite directions.

Adjust a two-saw (or more) edge trimmer, setting the gap between cutting discs, manually. Later models of two-saw edge trimming machines are equipped with electronic controls; there is no need to mechanically reconfigure the machine yourself. The rotation speed is changed by a switch, and a laser ruler is used to accurately position the board on the table.

Servicing of this type of equipment during operation is carried out by 2 people.

How to make a hand loom

You can make an edge trimmer yourself after some preliminary preparation. It is necessary to determine the main parameters of the future equipment, develop drawings of the edge trimming machine, and provide for the main and auxiliary equipment. It is useful to take into account the technical solutions of standard analogues famous manufacturers. Every homemade version finds wider application if unified by raw materials and products.

The initial data can be specifications taiga installations:

engine power from 5.5 kW for a single-saw k1 to 15 kW for a two-saw k-2m;
circular saws ø 450 – 500 mm;
rotation speed – 3000 rpm;
adjustable distance between saws 50 – 340 mm;
cutting depth 85 – 105 mm;
permissible board dimensions 6.5 × 0.6 m.

The frame for placing the workpiece is welded from a channel to fit the size of the workpiece inside the passage of the cutting element. The main criterion is stability and lack of vibration during operation. Height 1 m. Guides for the carriage rollers are welded on the longitudinal sides.

It is better to make a homemade unit with a movable saw unit. This will allow you to control the feed speed and quality of the cut, and reduce defects.

We assemble the moving part from 2 U-shaped racks connected by a crossbar. This is a frame for mounting powered edge trimming saws.

The cleanliness of the cut can be improved by setting the overdrive gear to 5000 rpm. The engine for a homemade cutting unit is from 4 kW (single saw) and above, the Ø of the disc for a single saw edger is from 250 mm.

As the number of disks increases, performance improves. A three-saw edger will allow you to effectively cut timber, glazing beads, and slats with a minimum of costs.

The edge trimming machine is designed for removing edges from the surface of wooden blocks and boards. This operation can be done on an ordinary band saw. But at the same time, it is difficult to achieve precision processing and create a product with the required geometry parameters.

Design of edge trimming machine

Edger with two saws

Before you start making an edger with your own hands, you need to familiarize yourself with the specifics of its layout and design. This woodworking equipment is mandatory for completing specialized production lines and is intended for pre-processing of lumber before sanding.

Edge trimming machines have standard equipment. They consist of a frame that performs two functions. It houses mechanisms for sawing, and can also serve as a conveyor for feeding workpieces. Alternative option is the rigid fixation of a wooden part on the surface of the working frame.

Depending on the design features differentiate following types woodworking edge trimming machines:

method of supplying materials - manual, automatic or semi-automatic. Manual models They are characterized by simplicity of design, but at the same time they have a low performance indicator. They are the best option For self-made;
in count saw blades- single and double saw. The former are intended for one-sided processing and are used extremely rarely. The optimal result is achieved after using two-saw models, since trimming occurs simultaneously along two edges of the workpiece;
movable or stationary carriage with saw blades. To make homemade woodworking equipment, it is recommended to make a subcutaneous carriage. This will allow you to control the processing process. But factory models are made with a fixed carriage. This helps improve productivity.

Additionally, a manual woodworking machine can be equipped with a system for removing cutting products - chips and wood dust. To do this, you can use a standard chip vacuum cleaner or its equivalent.

The optimal power of the power plant should be 4 kW or more. This is necessary for simultaneous processing of workpieces using a manual two-saw woodworking machine.

General diagram of an edge trimming machine

At the first stage, it is necessary to draw up a design diagram of the equipment. It should include exact drawing, which indicates the location and main characteristics of the constituent elements. Without this, it will be impossible to make a high-quality and reliable edge trimming machine.

The best option for self-production would be a design with a movable carriage. To implement it, you can use a two-saw or four-saw cutting unit controlled manual mechanism. The latest edge trimmers will be able to form two workpieces in one pass. But at the same time, they will require a powerful power plant to operate.

Structural elements of manual woodworking equipment:

support frame. The workpiece will be fixed on it. It is best to make it welded from profile pipes square section. The upper ones will be designed to move the carriage. Roller guides are attached between the side machines. With their help, you can feed workpieces with large mass. For fixation wooden parts You can use clamps or similar devices;
movable carriage. They install on it power unit, which is connected to the drive shaft using a belt drive. To mount the disks, a special shaft must be made with the ability to change the position of the disks. The carriage moves along the frame guides using wheels.

Additionally, a lifting block should be provided to adjust the cutting depth. In this way you can significantly increase maximum thickness blanks.

The control unit should be located on the side of the equipment. To increase the safety of operation of the woodworking machine, it is necessary to install a shield on the carriage. This way you can avoid chips getting into the electric motor.

Model with two electric motors

To reduce the design, two power units can be mounted on a homemade edge trimming machine. This will make it possible not to make a belt drive system, which will greatly facilitate the manufacturing process.

To move the carriage along the guides, you can make a long handle. Next to it there are usually buttons for activating/deactivating electric motors. This will make it possible to control the processing process from a safe distance.

In addition, the following additional components can be installed on edge trimming machines:

ruler;
cut depth indicator;
a protective mechanism that prevents motors from overheating.

Most often, improvised components are used to make this. Therefore, it is impossible to give clear recommendations for assembly. The technology directly depends on the characteristics of the constituent elements.

For example, you can see the design and operation of a homemade woodworking edge trimmer:

How to make a circular sawmill with your own hands

A modern circular sawmill is a convenient, functional tool for cutting wood.

With its help, even alone you can cope with a significant amount of work in a short time.

But not everyone is ready to pay for the purchase of a circular sawmill. Moreover, many believe that it is much better to make a circular sawmill exclusively with your own hands from scrap materials. What can be advised to those who have decided to take such a step?

If you have set yourself a similar goal, then the disk is for circular saw best made from duralumin or steel sheet, the thickness of which is at least 3 mm.

In this case, the diameter of the disk should be around 500 mm. How many teeth should such a disk have? If we talk about creating a sawmill for cutting wood, then only 2-3 will be enough.

DIY edge trimmer

This disc can easily handle cutting most species. And the one equipped with it is homemade or purchased disc sawmill will be quite functional.

In addition, when answering the question of how to make a circular sawmill at home, it is necessary to clarify the engine power. It should be about 2 kW.

No less important correct design guide.

The simplest version is a U-shaped saddle. It is formed from boards in the shape of a log, freed from branches and roughly processed with a plane. A motor with a circular saw is attached to the saddle.

But the most important thing you have to do if you need a homemade, but high-quality circular sawmill is to make cutting teeth.

The main requirements for them are quality material, correct cutting angle and careful balancing. The best material for the manufacture of cutting teeth will be high speed steel. And the workpieces from which it will be easiest to cut them are a carbide plate or a broken drill. The cutting angle of future teeth should be 30 degrees.

In this case, the rear angles must be equal to at least 15 degrees. And remember, if the cutters are not well balanced, you will have to deal with them rubbing against the walls of the cut.

And, of course, you need to pay attention Special attention ensuring the proper level of safety when working with this type of machines.

Applications and types of edge trimming machines: double-saw or single-saw

Disc twin-shaft multi-rip machine "Avangard MD2-22"

The Avangard-MD2-22 circular multi-saw machine is designed for sawing double-edged timber up to 600 mm wide from any type of wood, including hardwood, into boards using circular saws corresponding to various types of wood.

Each of the Ts2K12F-1 and Ts2K20F-1 machines, in addition to two saws, is additionally equipped with two milling heads, on which it is possible to perform format processing of panels to size along the length and rail with simultaneous milling of their edges. Processing of the edges of panels, frames and boxes can be done on a two-saw format-edging machine TsF-3.

For cutting wood boards and plywood into blanks, circular saw multi-saw machines are used: TsTZF-1 (three-saw), TsT4F (four-saw) and TsTMF (eleven-saw with program control).

For longitudinal sawing of boards or their segments into workpieces of the required width or thickness, circular saw mortising machines with mechanical feed are used: roller-disk - TsA2A (single-saw) and with a conveyor - PDK4-1 (single-saw), TsDK5-2 (five-saw) and TsMR -3 (ten-saw blades), which provide through-processing.

The single-saw cutting machine with conveyor feeding TsDK5-3 DK-200 consists of the following components: a table, a clamping support in the form of a box, which contains spring-loaded rollers that provide clamping of the workpiece in front and behind the saw.

The feed mechanism is made in the form of a conveyor made of cast iron links, hingedly connected by rollers with a bushing purpose. This chain is meshed with the rear drive sprocket, which is driven by the variator from the electric motor.

To prevent the material being cut from being thrown out of the machine, a riving knife is installed, and there are anti-ejection stops on the front of the machine.

The saw support of the machine consists of an electric motor, the shaft of which is connected through a coupling to the spindle on which the saw is fixed. The TsDK4-3 DK-200 machine has technical data: the greatest width of processed materials is 315 mm with a thickness of up to 100 mm, and the shortest length is 600 mm, feed speed 8-40 m/min, saw diameter 250-400 mm, rotation speed 3000 rpm min, electric motor power 13 kW.

Multi-saw cutting machines TsDK5-2, TsMR-3 differ from single-saw machines by the presence of a block of saws mounted on one shaft.

The distance between the saws determines the width of the sawn workpieces and is achieved on the shaft of the intermediate washers between the saws.

Do-it-yourself edger

The saw shaft of the machines is driven into rotation by an electric motor through V-belt transmission, feed drive control is stepless.

IN circular saws use round flat saws with set teeth with a diameter of 250-500 mm and a blade thickness of 2-2.8 mm.

The number of saw teeth ranges from 36 to 72, and the amount of spread on one side can be 0.3-0.6 mm. The teeth of saws for cross-cutting wood have an oblique sharpening, for rip sawing- direct sharpening. Fine-tooth planing saws are used to obtain smooth surface wood or saws, the teeth of which are equipped with carbide plates, for cutting hardwood boards, plywood, decorative plastics, wood and other boards.

Before installing the saw on the machine shaft, it must be checked.

The saw blade must be flat and free of cracks. The saw teeth must be correctly set and well sharpened. Sharpening saws and others cutting tools machines are produced by highly qualified fitters using special sharpening machines using electrocorundum grinding wheels. Saws equipped with carbide are sharpened on diamond sharpening wheels.

Design of edge trimming machine

Edge trimming machines have standard equipment. They consist of a frame that performs two functions. It houses mechanisms for sawing, and can also serve as a conveyor for feeding workpieces. An alternative option is to rigidly fix the wooden part to the surface of the working frame.

Depending on the design features, the following types of woodworking edge trimming machines are distinguished:

method of supplying materials - manual, automatic or semi-automatic. Manual models are simple in design, but have a low performance indicator. They are the best option for self-production;
by the number of saw blades – single and double saw blades. The former are intended for one-sided processing and are used extremely rarely. The optimal result is achieved after using two-saw models, since trimming occurs simultaneously along two edges of the workpiece;
movable or stationary carriage with saw blades. To make homemade woodworking equipment, it is recommended to make a subcutaneous carriage. This will allow you to control the processing process. But factory models are made with a fixed carriage. This helps improve productivity.

Additionally, a manual woodworking machine can be equipped with a system for removing cutting products - chips and wood dust. To do this, you can use a standard chip vacuum cleaner or its equivalent.

The optimal power of the power plant should be 4 kW or more. This is necessary for simultaneous processing of workpieces using a manual two-saw woodworking machine.

At the first stage, it is necessary to draw up a design diagram of the equipment. It must include an accurate drawing indicating the location and main characteristics of the constituent elements. Without this, it will be impossible to make a high-quality and reliable edge trimming machine.

The best option for self-production would be a design with a movable carriage. To implement it, you can use a two-saw or four-saw cutting unit controlled by a manual mechanism. The latest edge trimmers will be able to form two workpieces in one pass. But at the same time, they will require a powerful power plant to operate.

Structural elements of manual woodworking equipment:

support frame. The workpiece will be fixed on it. It is best to make it welded from square profile pipes. The upper ones will be designed to move the carriage. Roller guides are attached between the side machines. With their help, you can feed workpieces with a large mass. Clamps or similar devices can be used to secure wooden parts;
movable carriage. A power unit is installed on it, which is connected to the drive shaft using a belt drive. To mount the disks, a special shaft must be made with the ability to change the position of the disks. The carriage moves along the frame guides using wheels.

Additionally, a lifting block should be provided to adjust the cutting depth. In this way, the maximum thickness of the workpiece can be significantly increased.

The control unit should be located on the side of the equipment. To increase the safety of operation of the woodworking machine, it is necessary to install a shield on the carriage. This way you can avoid chips getting into the electric motor.

In addition, the following additional components can be installed on edge trimming machines:

ruler;
cut depth indicator;
a protective mechanism that prevents motors from overheating.

Most often, improvised components are used to make this. Therefore, it is impossible to give clear recommendations for assembly. The technology directly depends on the characteristics of the constituent elements.

For example, you can see the design and operation of a homemade woodworking edge trimmer:
