摘要
核电厂电气贯穿件端板为奥氏体不锈钢材料,组合孔结构复杂且数量多、精度要求高。根据端板所用材料——0Cr18Ni9不锈钢锻件的切削加工性以及零件的加工难点进行分析,研究出了一套适合端板组合孔加工的工艺路线,并对端板组合孔加工工艺中的关键工艺、切削参数等进行了详细介绍。
The endplate of NPP EPA is austenitic stainless steel that combined roll is complex structure, large amount and high accuracy. According to function characteristic, machinability and processing difficulty of about stainless steel forging 0CrlSNi9, a set of route process and cutting parameters is introduced for machining endplate hole.
