用指形齿轮铣刀(以下简称指状铣刀)加工大模数齿轮,是重型机械厂常用的方法,铣刀螺旋槽为等导程,因而在铣刀大端和小端螺旋面上所形成的工作前角是不相同的,切削性能差,因此要提高指状铣刀的切削效率和寿命,需将铣刀的导程随渐开线外形改变,以获得螺旋刃具有相等的工作前角,这种变导程指状铣刀可采用机械刃磨,保持刃磨精度和重复使用性。使用这种
With finger gear milling cutter (hereinafter referred to as the finger milling cutter) processing large modulus gear, heavy machinery factory is commonly used method, cutter spiral groove for the lead, and so on the cutter end and the small end of the spiral surface Forming the working angle is not the same, cutting performance is poor, so to improve the cutting tool finger cutting efficiency and life, you need to change the milling cutter lead with the involute shape, in order to obtain the spiral edge has the same work before Angle, this variable guide finger cutter mechanical sharpening can be used to maintain the sharpening accuracy and reusability. Use this
