Grinding Combination of Electrochemical Smoothing On SKH 51 Surface

A new finish mode combination of grinding and electrochemical smoothing executes a finish processes on SKH 51 surface is investigated. In the experiment, a high rotational speed of finish tool produces a better finish. A thin electrode associated with higher current density provides a larger discharge space for a better finish. The design change from a full form finish-tool to a partial finish-tool leads more discharge space, which creates better finishes than full form tool. It is a great contribution that the synchronous finish processes has a high efficiency than the electrochemical smoothing to make the workpiece surface smooth and bright.
