蜗轮在一般中小型工厂只能采用飞刀或用齿轮滚刀加工,加工精度较差。为了提高蜗轮加工精度,我们设计了短螺旋硬质合金机夹滚刀(附图),较好地解决了这一问题。经两年实践,证明此刀性能良好,一般工厂均能自制,对于模数m>6以上的蜗轮加工有一定参考价值。一、简介现以m=10,q=8、a_0=20°、K=1的短螺旋硬质合金机夹式蜗轮滚刀为例。 Worm gear can only be used in general small and medium-sized factories or gear hobs, machining accuracy is poor. In order to improve the machining accuracy of the worm gear, we designed a short helix carbide cutter clip hob (with photos), a better solution to this problem. After two years of practice, this knife proved good performance, the general factory can be self-made, for the m> 6 worm gear processing above have some reference value. I. Introduction Now with m = 10, q = 8, a_0 = 20 °, K = 1 short spiral hard alloy clip-type worm hob cutter as an example.
