||In this study, a conductive polymer was used as a tool electrode to finish the stainless steel by the rotary electrochemical buffing method. The effects of current, load, and particle size on the histories of the surface profile and roughness.|
In this experiment, the direction of rotation for the workpiece and the tool electrode was the same. When the operative parameters were set for the current of 13.5 mA, the load of 15 N, the surface of the stainless steel was polished using the pure electrochemical polishing for 6 minutes, so that Rmax could be reduced from 0.5 μm to 0.3 μm. Under a certain of load and machining time, when the stainless steel was polished using the only abrasive particles, Rmax could be reduced to 0.28 μm. Combining the electrochemical polishing and the abrasive machining, Rmax could be reduced to 0.228 μm and 0.113 μm for the particle sizes of 1 μm and 3 μm, respectively. Finally, when the machining time increased to 12 minutes, a smooth and bright stainless steel surfaces could obtain, so that Rmax could be reduced to 0.088
μm, and Ra from 0.08 μm to 0.01 μm.
