Description

Laboratory multifunctional precision sliding table saw and its usage method

technical field

The present invention relates to a sliding table saw and method of use thereof.

Background technique

Sliding table saw is a kind of cutting tool, which is generally composed of frame, fixed table, sliding table and saw blade mechanism. When in use, the sample is usually placed on the sliding table and pushed to the rotating saw blade mechanism to Realize the cutting operation.

However, due to reasons such as unsuitable backing and loose fixation, the sample is prone to displacement during the cutting process, which affects the cutting accuracy. The cutting accuracy is only ±4mm, and the scrap rate is high. On the other hand, the operator often directly pushes the sample by hand. Cutting, while the saw blades of the sliding table saw are directly exposed outside, it is easy to cut the operator's hand during the sample cutting process, resulting in safety accidents.

When the sample is too large, the guide screw can be adjusted by rotating the nut. The ruler rotates away from the worktable, and is compressed and processed by a pneumatic compression device. The flexible design of the ruler embodies humanization and rationalization, as long as the sample size is within a reasonable range, it can be adjusted by the ruler.

4. An electronic display caliper is fixed on one side of the workbench, and the value displayed on the electronic display is the distance from the side of the ruler close to the circular saw blade to the circular saw blade. This integrated design is easy to operate, compared with small laboratory cutting machines Improve the cutting accuracy by about 60%, and improve the operating efficiency.

5. The circular saw blade is covered with a saw case to prevent sawdust from splashing, and a sawdust storage room is designed under the sliding groove for convenient and quick storage of sawdust.

6. There is a stepless speed change system inside the sliding table saw box. When cutting wood products such as relatively tough materials, it can be adjusted to high speed to achieve fast cutting. When cutting plastics, such relatively brittle materials It can be adjusted to a low speed to prevent brittle fracture, and the speed can be adjusted according to the properties of different samples to achieve precise cutting.
