蜗杆的加工方法大致有4种: (1)用车刀切削: (2)用圆盘铣刀铣削; (3)用滚刀滚削; (4)用插刀插削。后三种加工方法虽然生产率高,但需特殊设备(或要改装现有设备),在一般工厂中采用较少;用车刀切削则无需特殊设备和刀具,各厂大都使用,但缺点是生产率低,如何提高生产率是许多机械制造工作者所要探索的问题。捷克斯洛伐克机器制造业生产革新者代表团 Worm processing methods are roughly four kinds: (1) cutting with a turning tool: (2) milling with a disc cutter; (3) Hob hobbing; Although the latter three methods have high productivity, special equipment (or existing equipment to be retrofitted) is required, and they are usually used less in general factories. There is no special equipment and tools required for cutting with turning tools, and most plants use them, but the disadvantage is that productivity Low, how to improve productivity is the problem to be explored by many mechanical manufacturing workers.
