Abstract

PURPOSE: To finish-grind very accurately by coinciding the moving direction of a grinding tool with the direction of filing marks of the previous process on the surface of a metal die.
CONSTITUTION: While the surface of a metal die 1 is ground with a grinding tool 2, the first vibrating table 10 or the second vibrating table 12 is microvibrated respectively in Y-direction or X-direction. The vibrating directions X and y are both horizontal to the moving direction of the grinding tool 2. A hydraulic cylinder 3 is actuated by the change of the load to the grinding tool 2, so that the copying locus of the grinding tool 2 forms zigzag curves and so a grinding direction component perpendicular to the finishing marks of the previous process is added to the grinding direction component of the grinding tool 2 in its moving direction (horizontal direction), therefore, the surface of the metal die 1 is ground very accurately.
