Abstract: Electrolytic composite polishing technology is a special processing technology developed on the basis of electropolishing theory. Essentially, the electrolysis is added to the effect of mechanical polishing in order to improve the polishing efficiency and reduce the loss of the polishing material. However, the control of polishing quality has always been a difficult point in the study of electrolytic composite polishing process. In order to explore the suitable parameters of electrolytic composite polishing process and improve the polishing quality, this experiment designed the experiment of electrolytic composite polishing of 304 stainless steel workpiece. Through the single variable factor experiment, the electrolyte composition, abrasive particle size, interelectrode gap and electrode were respectively made. The variable experiment of the rotational speed and the relative motion speed, by analyzing the experimental result data, the variation law of the univariate factors affecting the polishing quality is obtained.
