Abstract
Reciprocation of wheels in electro-mechanical grinding was investigated with a handier tool. Vitrified wheels and resinoid wheels with smaller grains were used. Co-Cr alloy and Ni-Cr alloy were ground using various current densities and the grinding surface texture was examined. The mechanical grinding with reciprocation of vitrified wheels with smaller grains showed better surface textures for both alloys, but the effect of current density on the electrolytic polishing surface differed between the two alloys. The electro-mechanical grinding surface was affected by the grinding load, and the effect of the mechanical grinding surface appeared at a load of 500g and the effect of the electrolytic polishing surface in the load of 100g. Resinoid wheels were found to be inferior to vitrified wheels for the electrolytic polishing but had some advantage in manufacturing. The electro-mechanical grinding with reciprocation of wheels was found to be a more practical method with respect to both the amount of grinding and the surface texture when the grain size of the wheel, the grinding load and the current density were set suitably.
