When does the saw blade need to be sharpened? How to judge?
1. Sawing material

2. The sound of sawing
The sharp saw blade has a crisp sound when cutting, the dull saw blade has noise, the sound is muffled or harsh, and it reminds you that the saw blade should be sharpened.
3. Sawing equipment

How to sharpen the saw blade
How to sharpen the saw blade correctly? Ensure that the saw blade reaches 80% of the grinding effect after grinding
1. Polish the front or back angle
At present, alloy saw blades usually grind the rake angle. When grind, keep the original angle of the saw blade unchanged, while keeping the grinding surface parallel to the welding surface of the saw blade. After the alloy saw blade has been sharpened several times, the sharpening angle can also be increased, but the sharpening angle requires professional equipment, so do not sharpen it yourself. If the grinding is careless, the life of the saw blade will be shortened and the cutting quality will be affected.
2. Grinding equipment
Small processing plants use traditional manual gear grinders. Because they are operated manually, it is easy to reduce the service life of the saw blade due to uneven strength and excessive grinding amount, or change the angle of the saw blade, resulting in the scrap of the saw blade. It is recommended that you use a fully automated gear grinding machine. At present, the price of the equipment for grinding the rake angle is also cost-effective, and the rear angle is still handled by the tool manufacturer. (Diamond Fickert Abrasives manufacturer china)
3. Selection of grinding suppliers
Do not choose a sharpening supplier that does not have the strength because of the low price. A strong supplier can effectively guarantee the quality and quality of the grinding.
