汽轮机汽缸中分面大螺孔攻丝是汽缸机械加工中一道关键工序。如攻丝质量不好会造成螺孔报废。螺纹质量差也给汽轮机检修造成不必要的麻烦,本文介绍一种单锥攻丝方法,该方法经在十多台产品上的试用,已取得了一些经验。
Turbine cylinder faceted large screw tapping cylinder machining is a key process. Such as poor quality tapping screw hole will result in scrapped. Poor thread quality also poses unnecessary troubles to the turbine overhaul. This paper presents a single taper tapping method that has gained some experience after being tested on more than a dozen products.
