Abstract: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, fl ow forms of electrolyte.The ECD results show that the burrs can be removed with good quality and effi ciency in the condition of optimal selecting parameters.
