Each sawmill includes a tape or disk high-performance sawmill, which allows you to process wood, receive edged and unedged building material. Most often, disk sawmills are used.
Design features
A household circular sawmill includes a table, a shaft and a cutting disc protruding above the plane of the working surface. The device is suitable for home. For an industrial scale, more advanced equipment will be needed, equipped with a rail track and a mobile operator’s cab. If the sawmill is equipped with several disks, each of them is driven by separate motors. A similar sawmill contains one or more saws. The figure shows a diagram of the equipment.
Equipment classification
Using a manual household circular sawmill, horizontal cutting is performed, the finished material has a flat surface. Sawing is carried out with a circular saw with a diameter of at least 500 mm. In this case, a cut in two directions is obtained, the saw rotates 90 °. Sawing machine with a rotary mechanism, depending on the functional purpose, can be horizontal and angular.
Horizontal machine
It features a simple collapsible design that provides mobility to the equipment, allowing it to be moved to a logging facility.
One of the main advantages is virtually waste-free production.
Sawing wood is carried out by moving the saw carriage moving along the log in both directions. There is no idling, which positively affects the performance of the equipment.
Steel saw blades with victorious spraying with a diameter of at least 550 mm are installed as cutters. These cutting elements guarantee an accurate cut, without chips, wave-like blemishes. On the sawmill case there is a remote control for controlling the unit.
Corner power-saw benches
They have a different sawing principle, can be equipped with one or more saw blades. Single-disc devices cut wood in the horizontal and vertical directions, do not have idle speed. The double-disc sawmill is characterized by orthogonal feed of the disks, while the cutting circles are horizontally and vertically with respect to each other.
Samples demonstrate high performance, good quality lumber processing. Large-scale woodworking plants are equipped with sawmill complexes, on the basis of which various materials are produced: timber, lining, edged board, and other products.
Features of self-assembly
The equipment can be assembled independently. To work, you will need:
- construction goats
- metal plates
- fasteners
- Electrical engine,
- tool for metal and wood.
The electric motor is sometimes replaced with gasoline, the equipment is used at the site of felling of trees, where there are no electrical communications.
Engine power must be at least 2 kW.
The simplest home-made unit for sawing trees consists of a working table and a shaft with a saw fixed under it, rotating due to a belt drive using a motor. For the manufacture of countertops, construction goats are used, fastened together by scraps of boards. Above them, plates of sheet metal with a thickness of at least 4 mm are installed. The plates are fixed with screws and special jumpers. A gap is left in the middle for the blade.
The video shows the process of sawing logs on homemade equipment.
Saw blades with a diameter of 500 mm are sold in stores, but they can also be made independently from three-millimeter duralumin sheets. For normal functioning, two to three teeth are enough, this will allow to process almost all wood species. When providing the teeth, it is necessary to observe a cutting angle of 30 ° and correct balancing. If you break the rule, the cutters will rub against the walls of the cut.
The unit under the table is fixed so that the disks are in the center of the technological gap between the plates on the countertop. The device is fixed to the table with screws through holes pre-drilled in the saw and base plates. The simplest guide for the sawmill is a U-shaped design. It is formed from boards to the size of a log, to which a motor with a saw is attached. The finished table is fixed to the bed with screws. The thrust bar during operation is held by clamps.
Models
Overview of some devices.
North 550
Angular sawmill with a rotary disk is presented in the segment of inexpensive and reliable equipment for sawing wood. Used in small factories, in private leshozes. The choice of the radial cut pattern of large logs is possible.
Altai 3
This circular sawmill works with all types of lumber: its saw blades are equipped with victorious soldering. Main advantages: ease of management, high performance.
Forester
It is equipped with rail segments, which, when docked, allow you to select the required cut length. The machine is equipped with automatic and manual feed of the carriage with saw blades, a special device for electronic regulation of the thickness of the finished lumber.
