Angle Selection for Tungsten Carbide Saw Tips
The angle parameters of the tungsten carbide tips is complex, also very special, meanwhile the correct selection of angle parameters is critical to decide the tungsten carbide saw tips’ quality .The main angle parameters are rake angle, flank angle and wedge angle .
The rake angle mainly influences power consumption in cutting woods. The bigger of the rake angle ,the sharper of its cutting edge ,meanwhile it is much easier to cut and feed materials. Generally speaking, for the soft wood, we usually take comparatively big rake angle, on opposite ,take the small one .
The angle of tungsten carbide saw tips is the position when it works ,which influence the cutting performance and effectiveness. Meanwhile the rake angle V,flank angle a and wedge angle B play more important influence on the cutting performance,the bigger of the rake angle ,the more light and high-speed of cutting performance,generally the rake angle range is 10~15°.The flank agnle is a separation angle between the tungsten carbide tip and the machined workpiece surface,its function is to prevent friction between them .The bigger flank agnle ,the less friction ,and the machined surface of the workpiece is more beautiful.Usually the value for the flank angle of tungsten carbide saw tip is 15°.The wedge angle is derived from rake and flank angle ,but it could not be too small ,as which plays to keep the tooth strength ,heat-diffusion and durability of the tungsten carbide saw tips .Anyhow ,the rake angle V,flank angle a and wedge angle B sum up is 90℃.
