用蜗轮滚刀加工蜗轮,最大优点是精度高、生产率高。但由于每一把蜗轮滚刀只能适应一种尺寸的蜗轮,因此在单件或小批生产中应用它是不经济的。在单件或小批生产中,往往用飞刀来加工。用飞刀加工蜗轮,通常有两种方法;一种是在万能铣床上加 Worm gear hobbing process, the biggest advantage is the high precision, high productivity. However, since each worm gear can only accommodate one size worm gear, it is uneconomical to apply it in a single or small batch. In a single or small batch production, often with a flying knife to process. Worm gear with a knife, there are usually two ways; one is universal milling machine plus
