small serrated blade angle selection

Serrated portion angle parameter is more complex, but also the most professional, and the correct choice of the blade cutting angle parameter is to determine the quality of the key. The router bits  main point of argument is the rake angle, clearance angle, wedge angle.
Rake angle sawing wood consumed by the main impact force. Serrated cutting rake angle greater sharpness better, more portable sawing, pushing more effort. Generally relatively soft material to be processed, the selected larger rake angle, otherwise choose a smaller rake angle.
Sawtooth angle is in  diamond cbn wheel the cutting position when the sawtooth. Serrated cutting angle affect performance results. Greatest impact is on the cutting rake angle γ, posterior horn α, wedge angle β. Rake angle γ is serrated cutting edge angle, the greater the cutting rake angle the more light, the rake angle is generally between 10-15 ℃. After the angle of the teeth and the angle between the machined surface, and its role is to prevent aliasing of the machined surface friction, the concrete blades  friction after the smaller the greater the angle, the more smooth processing of products. Carbide saw blade rear corner general value 15 ℃. Wedge angle is the angle from the front and rear angles derived. However, the wedge angle is not too small, it plays the strength to keep the teeth according to, heat resistance, durability of the effect. Rake angle γ, posterior horn α, wedge angle β is equal to the higher of 90 ℃.
