众所周知,由于蜗轮滚刀的专用性,常始单件小批量的蜗轮加工带来困难,若用飞刀切制蜗轮,对于没有切向进给的滚齿机也是很麻烦的事,用普通铣床加工,不仅不方便,精度也不高。在精度要求不高的情况下,最方便的方法是直接采用齿轮滚刀切制。但齿轮滚刀加工蜗轮滚刀两者标准不一,齿轮滚刀可视作斜齿轮, As we all know, due to the special nature of the worm hob, usually a single small batch of worm gear processing difficulties, if the use of flying knife cutting worm gear, there is no tangential feed hobbing machine is a very troublesome thing, with ordinary milling machine, Not only inconvenient, accuracy is not high. In the case of less demanding accuracy, the most convenient way is to directly cut with a gear hob. However, hob gear cutting hob hob both standard, gear hob can be regarded as helical gear,
