What Is a Panel Saw?

Precision panel saws (or table saws) can be used for the longitudinal section and cross-section of various artificial boards such as veneered particleboard, fiberboard, plywood and solid wood boards, plastic boards, aluminum alloys, etc. Industry and wood processing industries such as vehicle and ship manufacturing are general equipment among woodworking machinery, and the market demand is relatively huge.

With the large-scale application of wood-based panels in panel furniture manufacturing, building decoration and other industries, traditional universal

Development of precision panel saws in China

The panel saw was first invented in 1906 by the German Odendo Weilheim. After more than a century of development, the panel saw has undergone tremendous changes. From the original simple panel saw to the most advanced CNC electric panel saw, the panel saw has gone through more than 100 years. China has produced precision panel saws for more than 20 years, and has gone through the road of introduction, digestion, absorption, continuous improvement and continuous development.

In 1975, in order to improve the technical level of China's wood processing industry, the China Trade Promotion Commission and the Ministry of Forestry invited some manufacturers of the Italian woodworking machinery manufacturing industry to introduce related products to China. At that time, the Italian company GIBEN introduced precision Panel saw technology. In 1983, Qingdao Yongqiang Woodworking Machinery Co., Ltd., Shanghai Furniture Machinery Factory and Nanjing Woodworking Machinery Factory successively produced precision panel saws. At the first International Woodworking Machinery Exhibition in Beijing in 1986, the participation of Italian precision panel saws caused widespread concern in China's furniture manufacturing and woodworking machinery manufacturing industries. Since then, more than 30 woodworking machinery manufacturing enterprises in China have begun to produce precision Panel saw.

With the advancement of mechanical processing and electrical engineering, the current cutting board has gradually developed to fully automatic. The addition of numerical control has made traditional cutting board products greatly improve the processing efficiency. For example, the lifting and tilting of the saw blade can be fully controlled by computer. Even the entire cutting process is complete

The main part of the panel saw includes a bed, a table, a longitudinal cross-section guide, a main saw, a scribe saw, and a transmission. The structure and working principle are similar to ordinary circular saws, and they can be used alone as ordinary circular saws.

Composition of panel saw:

1. Frame; 2. Main saw part; 3. Slot saw part; 4. Lateral guide baffle; 5. Fixed workbench; 6. Sliding table; 7. Miter saw guide plate; 8. Bracket; 9. Oblique Saw angle display device; 10. Side guides.

The main structural feature of the table saw is the use of two saw blades, namely the main saw blade and the scribe saw blade. When cutting, the scribe saw is cut in advance, and the grooves with a depth of 1 to 2 mm and a width of 0.1 to 0.2 mm thicker than the main saw blade are first sawn on the bottom surface of the plate to be processed to ensure that When the main blade is cutting, the edge of the cutting edge will not tear, so as to obtain good cutting quality. Scribing saw blades have a small diameter, usually around 120mm, and are driven by a separate motor. The speed of the saw blade is generally above 9000r / min, and the cutting speed is generally 56-60m / s. It is required that the scribe saw blade and the main saw blade are aligned in the same vertical plane. The diameter of the main saw blade is generally 300 ~ 400mm, which is driven by the main motor through a V-belt. According to the diameter of the main saw blade and the type of the processed board material, the main saw blade can use the tower wheel for speed change. The speed change structure of the tower wheel is simple and it has a constant power output, which is more in line with the actual needs of wood processing. The power of the main motor is generally 4-9kw. In order to make speed adjustment easy, a special V-belt is used to ensure that a single belt can meet the required power transmission. The rotation speed of the main saw blade is generally 3000 to 6000 r / 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 table saw is that the scribe saw blade and the main saw blade can not be moved, and the mobile workbench made of aluminum profiles carrying the processed plates is moved back and forth by hand to realize the sawing process. Due to the special structure of the guide plate of the moving table, it is light and labor-saving when manually pushing the feed, and the machining accuracy is very high.

The bed of the push table saw is mostly welded from 5 to 6 mm thick steel plates, which is stable and beautiful, and can ensure that its early sawing process does not produce tilt and distortion. The fixed table is fixed on the top of the bed. It is required to be flat and not deformed, and a longitudinal cutting guide and its adjusting mechanism are provided.

The moving table is the key part of the panel saw, and it is also the main part that is different from the ordinary circular saw. The moving table is composed of a bracket, a lower rail, a roller, and a pushing table. Its prominent features are: (1) Light and labor-saving operation, large driving stroke and large cutting width; (2) With a stable and lightweight trailer, the operation is stable; (3) The setting of the mobile table and the main saw blade can be adjusted by 45 degrees, expanding the sawing machine Some of the saws are also equipped with a milling device, which can process grooves and grooves with a width between 30-50MM. ^[2]

Instructions for panel saw operation

1. Before starting the machine tool, you must carefully check whether the saw blade pad, the compression nut and the screws in various parts are firm. If you find any looseness, tighten it in time. When installing the saw blade, pay attention to the cutting direction and cannot be reversed.

2. Precision sliding table saws are not allowed

1.According to the workload, the dust removal operation should be performed on the inside of the machine regularly to ensure the normal heat dissipation of the motor.

2.Dust the track of the pusher regularly to ensure the smooth operation of the pusher

3. Regularly inspect the belt and find that it should be replaced in time

4.Regularly lubricate the body to be lubricated to ensure the stability and quietness of the equipment.
