冶金、矿山和建筑机械设备中，大量使用蜗轮蜗杆减速器，蜗轮到的加工，修配就成了生产中的关键。任何一个机械厂都无法提供品种繁多的专用蜗轮滚刀，在急需蜗轮配件时，采用飞刀来加工蜗轮，结果既达不到精度要求，又无法提高生产效率，并且装配时必须进行大量的修配工作，因? Metallurgy, mining and construction machinery and equipment, extensive use of worm reducer, worm gear to the processing, repair has become the key to production. Any one machinery factory can not provide a wide range of special worm hob, worm gear parts in the urgent need to use the worm to process the worm, the result of both the accuracy requirements, but also can not increase production efficiency, and the assembly must be a lot of repair Work, because?
