摘　　要：偏心轴承偏心环定位孔位置精度要求较高,热处理后采用线切割方法加工。原有的线切割加工方法较为繁琐,严重影响加工效率及产品质量。针对存在的问题,改进了线切割加工装备,提高了加工效率和质量。The precision requirements of the eccentric ring positioning holes for the eccentric bearing is higher, the positioning holes of the eccentric ring were processed using line-cutting method after the heat treatment process. The original line cutting method was more complicated, seriously affected the processing efifciency and product quality. In view of the existing problems, the line cutting equipment was improved, the processing efifciency and quality were increased.
