OUTER PERIPHERY POLISHING METHOD AND DEVICE FOR DISC SHAPED WORKPIECE

摘要

PURPOSE:To automatically and uniformly polish all the outer periphery upto a prescribed size (diameter) at a low cost. CONSTITUTION:A disc shaped workpiece 11 charged into a peripheral slit 9 near the outer periphery of an approximately horizontal circular revolution plate 1 is transferred to a rotation plate 14 even with a fixed plate 12 at the lower side of the revolution plate 1 while being supported by the fixed plate 12 at the lower side of the revolution plate 1 in an upward protruded manner, and passed under a grinding wheel 23 at the upper side of the revolution plate 1 while being rotated in the slit 9 with the rotation of the rotation plate 14, so that the outer periphery is polished to a prescribed diameter.
