Burnishing and Electrofinishing in Screw Surface Polishing

Abstract:

The current study discusses the surface finish of several common die materials, of which the screw-surface is finished by compound processes of electrochemical finishing and burnishing. The burnishing-tool uses ceramic material connected with the electrode and moves, following the electrode, to burnish the workpiece. In the experiment, the electrode is used with a continuous and pulsed direct current. The results show that the use of a higher rotational speed for the electrode and burnishing-tool is advantageous to the finish. A partial form with a thinner heavy section performs the best finish effect in the current investigation. Pulsed direct current can slightly improve the finish effect. The burnishing process can increase the finish effect. An effective and low-cost finish processes through burnishing assistance following electrochemical finishing after screw machining offers a fast improvement for the surface roughness of the screw-surface and is a new application in the screw finishing process.
