Apparatus and method of electrochemical polishing by ring-form electrode
An apparatus and method of electrochemical polishing a workpiece with ring-form electrode is provided. A mechanism with a tool electrode, a DC power supply and electrolysis-supply tank of the present invention can be installed on the traditional production equipment. The tool electrode is connected with the negative pole of the DC power supply, while the workpiece is connected with the positive pole of the DC power supply and kept a fixed distance from the tool electrode. The electrode or the workpiece advances at a predetermined feeding speed while the workpiece is electrochemically polished. The present invention uses the centrifugal force of rotational tool electrode to discharge electrolytic byproducts, making electrochemical polishing more effective.
