The main machine part of the sliding table saw includes the machine body, working table, longitudinal and transverse section guide plate, main saw, scoring saw, transmission and other parts. The structure and working principle are the same as the ordinary circular saw machine, and can be used separately as the ordinary circular saw machine.
The composition of the sliding table saw:
1. Rack; 2. Main saw part; 3. Groove saw part; 4. Transverse guide baffle; 5. Fix the workbench; 6. Sliding sliding table; 7. Diagonal saw guide plate; 8. Bracket; 9. Angle display device of diagonal saw; 10. Lateral guide baffle.
The main structural feature of the sliding table saw is the use of two saw blades, namely the main saw blade and the scoring saw blade. When cutting, the scoring saw shall cut in advance, and a groove with a depth of 1~2mm and a width of 0.1~0.2mm thicker than the main saw blade shall be cut on the bottom surface of the processed plate to ensure that the edge of the saw blade will not tear when the main saw blade is cutting, so as to obtain good cutting quality. The scoring saw blade has a small diameter, usually about 120mm, and is driven by a separate motor. The rotating speed of the saw blade is generally above 9000r/min, and the cutting speed is generally 56~60m/s. The scoring saw blade and the main saw blade shall be aligned in the same vertical plane. Diameter of main saw blade&8943; It is generally 300~400mm and is driven by the main motor through the V-belt. According to the different diameters of the main saw blade and the types of processed plates, the main saw blade can use the tower wheel for speed change. The tower wheel speed change structure is simple and belongs to constant power output, which is more in line with the actual needs of wood processing. The power of main motor is generally 4~9kw. In order to make the speed regulation simple, special triangular belt is used to ensure that the transmission of required power can be satisfied with a single belt. The rotation speed of the main saw blade is generally 3000~6000 r/min, and the distance between the main saw blade and the scoring saw blade is generally about 100 mm.
Another main structural feature of the sliding table saw is that the marking saw blade and the main saw blade are stationary, and the moving table made of aluminum profile containing the processed plate is pushed forward and backward by hand to realize sawing. Due to the special structure of the guide rail of the mobile workbench, it is light and labor-saving to manually push the feed, and the processing accuracy is very high.
The bed of the sliding table saw is mostly welded with steel plates with a thickness of 5~6mm, which is stable and beautiful, and can ensure that its early sawing processing seeds do not produce tilt and distortion. The fixed table is fixed on the top of the bed, and the casting parts of Sichuan are required to be flat and not deformed. It is also equipped with a longitudinal cutting guide plate and its adjustment mechanism.
The sliding table part is the key part of the sliding table saw, and is also the main part that is different from the ordinary circular saw machine. The moving table is composed of bracket, lower guide rail, roller, sliding table, and other parts. Its prominent features are: (1) easy and labor-saving operation, large driving stroke, and large cutting width; (2) Attached with a stable and light towing frame, running smoothly; (3) The setting of the mobile workbench and the main saw blade can be adjusted by 45 degrees, which expands the scope of use of the saw machine. Some saw machines are also equipped with milling devices, which can process grooves and grooves with a width of 30-50MM.
