である。(Effects of the invention) The jig of this invention consists of a combination of a hook part, a frame, a clamping tool, and a presser bar. You can use materials with
Alternatively, the clamping tool, presser bar, etc. can be made of a rigid and heat-resistant synthetic resin material, and can form a linear electrically conductive contact directly with the processed part to ensure good adhesion. It is stable and has fewer conduction defects than conventional jigs, the current distribution to the processed parts is more uniform, and the finish of electrolytic polishing is good. It is of practical value because it can uniformly electrolytically polish the entire surface of the workpiece by immersing it in a polishing solution to form a good specular glossy surface on the surface of the workpiece.
