铰削是内孔的精加工工序,掌握时较一般钻孔、扩孔为难。对不锈钢材料进行铰削,由于工件材料本身具有韧性大、热强度高、加工硬化趋势强、切屑的粘附性强和导热性差等特性,大大增加了加工过程中的复杂性和困难程度。因此,对 1Cr18Ni9 Ti 等奥氏体类不锈 Reaming is the finishing process of the hole, mastered more than the general drilling, reaming difficult. Reaming the stainless steel material, the workpiece material itself has a large toughness, high thermal strength, strong tendency to work hardening, chip adhesion and poor thermal conductivity and other characteristics, greatly increased the complexity of the process and the degree of difficulty. Therefore, 1Cr18Ni9 Ti and other austenitic stainless steel
