摘　　要：汽轮机汽缸、水轮机转轮体等大型铸钢件上有许多超过M36,甚至达到M150的螺纹孔,常规麻花钻和丝锥加工的办法工时效率太低。文中探讨一种使用可转位刀片钻加工底孔和螺纹铣刀铣削螺纹的工艺方法来解决这个问题。There are many M36~M150 threaded holes on large steel castings such as steam turbine cylinders and turbine runners.The working efficiency of conventional twist drills and taps is too low.This paper proposes a process for drilling a hole with an indexable insert and milling the thread with a thread milling cutter to solve this problem.
