Design of Screw-Surface Finish Using Burnishing Assistance Following Electrochemical Finishing

Abstract

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 is a new application in the screw finishing process. The burnishing-tool uses ceramic material connected with the electrode and moves, following the electrode, to burnish the workpiece. The results show that the use of a higher rotational speed for the electrode and burnishing-tool is advantageous to the finish. Pulsed direct current can slightly improve the finish effect. A partial form with a thinner heavy section performs the best finish effect in the current investigation.
