摘　　要：采用电化学方法对不锈钢管壁上钻削的微小孔与不锈钢管内壁相贯处难到达区域的毛刺进行去除。实验研究了加工时间、电解液成分与浓度、电解液流动方式对微小孔毛刺去除质量的影响以及相应条件下阴阳极极间电压的变化规律。研究结果表明:在优选的加工工艺参数条件下,可有效地去除微小孔毛刺。The electrochemical deburring(ECD) is adopted to remove burrs which exist in the intersections of the miniature drilling holes and the inner wall of stainless steel pipe.By processing experiments,the influences of the machining parameters on the deburring quality and the change law of the voltage between the electrode and workpiece are explored,such as process time,electrolytic composition and concentration,flow forms of electrolyte.The ECD results show that the burrs can be removed with good quality and efficiency in the condition of optimal selecting parameters.
