摘要
在分析了万吨桨起吊孔和油孔的加工特点后,给出了使用小万向钻和特殊钻头以及间歇进给和退出的办法进行万吨桨油孔的深孔加工;使用小万向钻和专用工装采用先钻后镗,分层切削,逐渐去除余量,扩大孔径直到设计尺寸。经过实际生产的检验,所设计的方案取得良好的效果,可以满足万吨桨加工需要。
This paper points out the characteristics of oil holes and lifting hole machining,and gives a new method to machining oil hole with small universal radial drilling machine and special twist dill,and intermissive feed and drawing out of the twist drill.Also gives the method to machining lifting hole with small universal radial drilling machining and special process tools,and cutting the material little by little until the design dimension is obtained.Apply these methods to the real production process,good results are obtained.
