Selection of cemented carbide saw blade (4)

The Angle parameters of saw blade are complicated and most professional, and the correct choice of Angle parameters of saw blade is the key to determine the cutting quality. The main Angle parameters are front Angle, back Angle and wedge Angle.

The front Angle mainly affects the force consumed by the sawdust. The bigger the front Angle, the better the cutting sharpness of the saw. The lighter the saw cutting, and the less effort the pushing material. Generally processed material material is soft, which should choose a larger front Angle. On the contrary, choose a smaller front Angle.

The Angle of the saw tooth is the position of the saw tooth when cutting. The Angle of sawtooth affects the cutting performance. The most significant effects on cutting are anterior Angle γ, posterior Angle α and wedge Angle β. Front Angle γ is the cutting Angle of the saw tooth, the greater the front Angle of the cutting is lighter, the front Angle is generally between 10-15℃. The back Angle is the included Angle between the saw tooth and the processed surface. Its function is to prevent the friction between the saw tooth and the processed surface. The larger the back Angle is, the smaller the friction is, and the processed products are more smooth and clean. The back Angle of carbide saw blade is generally 15℃. Wedge angles are derived from front and rear angles. But the wedge Angle can not be too small, it plays a role in maintaining the strength, heat dissipation and durability of the teeth. The sum of anterior Angle γ, posterior Angle α and wedge Angle β is equal to 90℃.
