To process the edges of MDF, chipboard or other similar varieties of modern sheet materials, you need to use special edging equipment. It is very difficult to do such work manually, without the use of special mechanisms. To get an excellent result, you need to do everything very painstakingly and subtly.
You can purchase such equipment, but it is very expensive. As a result of this, a more economical option would be a home-made edge banding machine, which, having the drawings, anyone can make.
How to make an edge trimmer with your own hands - Metals, equipment, instructions
Any woodworking shop from small to large is faced with the problem of a huge amount of waste in the process of processing logs.
On a sawmill, rough cutting of logs is carried out until a square beam is obtained. Then, if necessary, the timber is cut into thinner bars or edged boards of the required size.
The implementation of processing rounded waste at a sawmill is not rational.
Multi-rip edger
However, the waste obtained from such production can be used further, and even make a profit from it. From them you can make edged boards of small thickness, glazing beads, as well as other useful products, for example, pieces of furniture. For these purposes, an edge trimming machine is installed in woodworking shops.
According to the type of power supply of the power unit, the equipment is divided into:
- electric
- on liquid fuel.
The sawing unit can move along the guides manually or automatically using an electric drive.
Based on the quantity, the edge trimmer can be:
- single saw. A single saw edger makes one cut in one pass. To cut the second side, the workpiece must be rotated
- two-saw. Such equipment cuts the board on both sides in one pass. On the Russian market you can purchase models Data Center 450, Taiga K2M and others
- multi-saw. In one pass of the workpiece, the shalevka is immediately cut into bars or boards of the required size.
Like any other machine, the edge saw has a frame on which workpieces and carriages with a motor that rotates the circular saws are placed. Such a machine can cut workpieces of any length and width, which significantly simplifies the work and reduces the amount of production waste.
Operation of an edger
The owner of each woodworking enterprise tries to minimize production waste for the most rational use of wood.
Often, sawmill shops install domestically produced devices, such as TsOD 450, Taiga, Kedr and others. In small workshops, they most often use machines created with their own hands from scrap materials.
Such machines make it possible to trim the rounded edges of shalevki and slabs to obtain an edged board. In addition, using an edge trimmer you can cut boards into bars and blanks with a thickness of 5 mm or more. The materials obtained in this way are used in the construction industry, as well as for decorating premises and creating furniture.
The operating principle of a single-saw, double-saw or multi-saw machine is the same. A wooden blank is placed on the bed, along which one or more circular saws moves. The carriage on which the saws rotate is moved by the machine operator manually or using an automatic system.
A single saw, like the TsOD 450, will require two passes to cut the edge on both sides. Most often, such machines are designed in such a way that trimming can be carried out by moving the carriage in both directions.
The double-saw edge trimming machine is designed in such a way that the circular saws rotate in different directions, cutting simultaneously from both sides, as a result of which labor productivity increases.
Multi-saw devices are needed for sawing wooden blanks into bars or boards of the required size. On such machines, up to 14 circular saws can be used simultaneously and in parallel.
In two-saw and multi-saw edge trimming machines, such as TsOD 450 or Taiga, the distance between the saws can be adjusted. This procedure on outdated models is performed mechanically, by the operator’s hands.
Modern sawing devices for wood have electronic control, which allows you to automatically arrange the saws in the desired position with millimeter precision.
In addition, such models have a laser ruler for setting workpieces and a function for switching saw rotation speeds.
The video will tell you in more detail how the edge trimmer works.
Domestic-made edge trimming machines of various modifications are sold on the Russian market. The significant difference in price is due to the quality and functionality of the devices. Imported options are also available. But their price is significantly higher.
The most popular single-saw machines are the Kedr and Taiga brands. Of the two-saw machines, the most popular are the TsOD 450, Taiga K2M, and Avangard models.
How to make a machine with your own hands?
It is unlikely that you can create a two-saw device yourself. Yes, it is not needed for household use. For an amateur workshop, a homemade single-saw edge trimmer is quite suitable. Creating such a device would be quite expensive. To create an edge trimmer, you will need:
- metal pipes, channels and angles
- electric motor
- shafts, for example, from agricultural machinery
- Circular Saw
- tools for working with metal, such as an angle grinder, drill, welding machine
- connecting elements - bolts, nuts, couplers.
The first step is to create a strong, reliable, stable frame. A poor-quality bed will cause vibrations, as a result of which crooked cuts appear and the saw deteriorates.
It is best to create a frame from metal channels. The legs must be welded to the frame welded from them.
After this, it is worth welding the corners to the top of the frame along the longitudinal sides and making a groove for mounting the shafts along which the cutting carriage will move.
In the shape of the letter “P” you need to weld metal channels to form the carriage. Next you need to weld the crossbar along which the saw will move.
The next step is the installation of the power unit. You need to choose it very responsibly.
If you decide to use a circular saw with a diameter of 250 mm, then you need to buy a motor that can provide a rotation speed of at least 5000 rpm.
After this, attach the motor to the frame so that it rotates the saw in a parallel direction to the longitudinal axes of the frame.

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. 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.
How to make an edge trimmer with your own hands
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.
Recommendations for DIY production
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.
Tips for equipping your equipment
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 look at the design and operation of a homemade woodworking edge trimmer:
