Grinding saw blades is a very common thing in work, but many people often don’t know when to grind them. In fact, there is time to choose. Below, the editor will tell you when is the best time to grind.

One is to judge from the surface of the sawn wood, such as the smooth surface of the wooden board cut by the new saw blade, without obvious fuzzing or misalignment of the upper and lower saws. Once these problems occur and no longer disappear, they should be promptly ground.

Secondly, based on the sound of sawing, generally speaking, the sound of a new saw blade is crisp, while the sound is dull when the saw blade should be sharpened.

Thirdly, it is judged based on the working power of the machine. When the saw blade should be ground, the machine’s working current increases due to an increase in load.

The fourth is to determine how long it takes for sawing and grinding based on management experience.

Next is how to correctly grind multiple saw blades.

At present, multi blade saw blades generally only choose to grind the front angle. The correct grinding method is to keep the original angle of the saw blade unchanged, while keeping the grinding surface parallel to the welding surface of the saw blade.

Both of these methods change the original angle of the saw blade, which can easily lead to shorter cutting time after grinding, and even cause problems such as blade deformation and burning;

The above is the knowledge about saw blade grinding. We hope everyone can understand it, which can help everyone use it better.
