耐热钢轴承斜油孔加工方法

摘要

分析耐热钢轴承内圈斜油孔加工存在的难点，通过改制钻头、优化切削参数和加工工艺，解决了曲面加工直径1 mm 以下深、斜油孔时钻头容易折断的问题。%The difficulties are analyzed for processing of oblique oil hole of inner rings for bearings made of heat resist-ant steel.By remanufacturing drill and optimizing cutting parameter and processing technology,the fracture problems a-bout drill are solved during curved face machining of oblique oil hole with a diameter below 1 mm.
