With the large-scale application of wood-based panels in the panel furniture manufacturing industry, construction and decoration industry, the traditional universal circular sawing machine can not meet the needs of its processing technology, no matter the processing precision or production efficiency. Therefore, a variety of circular sawing machines dedicated to sheet metal cutting, a woodworking panel saw, has been rapidly developed. From small-scale panel saws with low-productivity manual feed or mechanical feed, to large-scale combination of digital program controllers or computer-optimized with automatic loading and unloading mechanisms with high productivity and automation.

The sawing system has been widely used in furniture manufacturing, building decoration, vehicle and ship manufacturing industries. Precision panel saws are used for longitudinal, cross-section or angled sawing of plywood, particleboard, fiberboard, veneer, laminated board, blockboard, spliced ​​solid wood and plastic panels to obtain dimensions panels. It can also be used for sawing of various insulation boards, thin aluminum sheets and aluminum profiles.

Regular size of common sliding table saw:
Precision sliding table saws are 2.8 meters, 3 meters, 3.2 meters, 3.8 meters.
Precision table saws are usually divided into cylindrical guides way and linear guides way.
The cylindrical guide rail is a bit more smooth on the table top, and it is less prone to deformation and damage, compared with linear guides way.

1.Body Structure:
The main part of the precision panel saw includes the bed, the table, the longitudinal section guide, main saw, groove saw, the drive and other components. The structure and working principle are similar to ordinary circular sawing machines, and can be used separately as ordinary circular saws.

2. The composition of the sliding table saw:
1) frame; 2) main saw part; 3) groove saw part; 4) transverse guide baffle; 5) fixed table; 6) sliding table; 7) oblique saw guide; 8) bracket; 9) Saw angle display device; 10) side guide baffle.

2.1 Saw blades size and power:
The main structural feature of precision panel saws is the use of two saw blades, the main saw blade and the groove saw blade. When cutting, groove saw pre-cut boards in advance, to make a groove on the bottom which depth from 1 to 2 mm and width of 0.1 to 0.2 mm thicker than the main saw blade. It can ensure the edge of the kerf does not tear when the main blade is cutting and get a good sawing quality. The groove 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 groove saw blade is required to align with the main saw blade in the same vertical plane.

The diameter of the main saw blade typically is 300-400 mm, 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 a special V-belt, it is guaranteed that a 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 groove saw blade is generally about 100 mm.

2.2 Saw blades processing:
Another main structural feature of the sliding table saw is that groove saw blade and 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 finish the sawing process. Due to the special structure of the guide plate of the moving table, the manual sliding and feeding is light and labor-saving, and the machining precision is high.

2.3. Panel saw bed
Most of the bed of precision cutting saws are welded with steel plates with a thickness of 5~6mm, which is stable and beautiful. It can ensure that the early sawing and cutting process does not produce tilting and twisting. The fixed workbench is fixed on the top of the bed. The casting part is required to be flat and not deformed, and is provided with a longitudinal cutting guide.
