What is the good angle of saw blade sharpening machine

 

 

1. The angle parameters of the sawtooth part are more complicated and *professional. The correct selection of the angle parameters of the saw blade is the key to determining the quality of the sawing. The main angle parameters are the rake angle, the rear angle and the wedge angle.

 

2. The rake angle mainly affects the force consumed by sawing wood chips. The greater the rake angle, the better the sharpness of the saw tooth cutting, the lighter the sawing, and the more labor-saving pushing the material. Generally, when the material to be processed is soft, choose a larger rake angle, otherwise, choose a smaller rake angle.

 

3. The angle of the saw tooth is the position of the saw tooth during cutting. The angle of the serration affects the cutting performance. The biggest influence on cutting is the rake angle γ, the relief angle α, and the wedge angle β. The rake angle γ is the cutting angle of the saw tooth. The larger the rake angle, the lighter the cutting. The rake angle is generally between 10-15°C. The clearance angle is the angle between the saw tooth and the machined surface. Its function is to prevent the saw tooth from rubbing against the machined surface. The larger the clearance angle, the smaller the friction and the smoother the processed product. The clearance angle of cemented carbide saw blades is generally 15°C. The wedge angle is derived from the front and back angles. But the wedge angle should not be too small, it plays a role in maintaining the strength, heat dissipation and durability of the tooth. The sum of the rake angle γ, the rear angle α, and the wedge angle β is equal to 90°C.
