First, check the saw blade with a flat ruler to see if it is congenital concave and convex, if any, pressure the convex surface first.
Starting from the middle, jump pressure between 8 mm and 10 mm apart. The strength is gradually reduced from the middle to both sides. Check the Radian with the Radian ruler while pressing, do not exceed the limit. Check and trim the back of the saw blade at the same time, no bending is allowed.
After one side is pressed, turn the bar over and check the other side. If there is any deficiency, keep pressing. Note, must follow the roller press, must not mess between the lines. Wait to meet the standards, and then check and repair, also along the roller press. When the backside is up to standard, the bar is finished.

Carpentry belt saw blade, applied to wood processing industry: Nowadays, the sheet material processing, especially such as mahogany and other hard wood, oil wood, bamboo wood processing basically need this saw blade processing. Its advantages are as follows:
1. Fast cutting.
2. The surface is smooth.
3. High parallelism of the processing board, can achieve the precision of 10 silk.
4, save the material, because the precision is high, the saw Mark is narrower, can effectively reduce the material loss
