The main structural feature of precision panel saws is the use of two saw blades, the main saw blade and the scribe saw blade. When cutting, the sawing saw is cut in advance, and a groove with a depth of 1 to 2 mm and a width of 0.1 to 0.2 mm thicker than the main saw blade is first sawed on the bottom surface of the plate to be processed. The edge of the kerf does not tear when the main saw blade is cut, resulting in good sawing quality. The scribe blade has a small diameter, usually around 120 mm, and is driven by a separate motor. The saw blade speed is generally above 9000r/min, and the cutting speed is generally 56-60m/s. The scribe saw blade is required to align with the main saw blade in the same vertical plane. The diameter of the main saw blade &8943; typically 300-400mm, is driven by the main motor through the V-belt. According to the main saw blade diameter and the type of processing plate, the main saw blade can be changed by the tower wheel. The tower wheel shifting structure is simple and belongs to constant power output, which is more in line with the actual needs of wood processing. The power of the main motor is generally 4 to 9 kW. In order to make the speed adjustment easy to use special triangle belts, it is guaranteed that the single belt can meet the required power transmission. The rotation speed of the main saw blade is generally 3000-6000r/min, and the distance between the main saw blade and the scribe saw blade is generally about 100 mm.
Another main structural feature of the precision panel saw is that the scribing saw blade and the main saw blade are fixed, and the moving table made of the aluminum profile carrying the processed plate member is moved forward and backward to realize the sawing process. Due to the special structure of the guide plate of the moving table, the manual pushing and feeding is light and labor-saving, and the machining precision is high.
The bed of the precision cutting saw is mostly welded with a steel plate with a thickness of 5 to 6 mm. It is stable and beautiful, and can ensure that the early sawing process does not produce tilting and distortion. The fixed table is fixed on the top of the bed. The casting parts are required to be flat and not deformed, and are provided with a longitudinal cutting guide and an adjusting mechanism thereof.
