摘　　要：介绍了高压共轨喷油器体进回油孔用电解去毛刺加工的原理、设备特点，对影响加工精度和效率的重要因素逐一 进行了分析，通过加工试验证明：采用电解去毛刺技术能够在喷油器进回油孔处获得过渡圆弧、清除切削毛刺、有效提高 产品清洁度，使喷油器总成流量稳定。This paper first introduced the theory of electrolytic burr elimination for inlet and outlet hole for high pressure common rail injector body, and the characteristics of the electrolytic equipment, then detailed analysis were made of the key factors which affect the manufacture accuracy and efficiency. Manufacture practice demonstrate that with the electrolytic burr elimination technique, the smooth transition circle could be obtained around the conjunction of inlet and outlet hole, thus can effectively increase cleanliness of injector body and make the fuel flow of the whole injector more stable.
