Title:
ELECTROLYTIC COMBINED GRINDING METHOD OF MIRROR SURFACE
Document Type and Number:
Japanese Patent JPS59169718
Kind Code:
A
Abstract:

PURPOSE: To efficiently form a mirror surface uniformly in roughness of 0.2μm Rmax or less, by combining the electrolytic action, which melts the metal in a metallic work of positive polarity to be removed, with the mechanical action by abrasive grains.

CONSTITUTION: A disc-shaped electrode 10 of negative polarity is mounted to the bottom end face of a base part 7, and the central part of said electrode is formed in a recessed part 11 or a hole part. An insulating and water-permeable grinding material 13 is mounted to the bottom face of the electrode 10, machining a metallic work 14 of positive polarity. Using an abrasive grain in a size of #800W#3,000, if assumed D (mm) for diameter of a tool surface, P (kgf/cm2) for pressing pressure of a grinding tool to the work, V (mm/min) for relative moving speed of the grinding tool with respect to the work and N (rpm) for number of revolution of the grinding tool, their relation is taken as V/(DN)<0.5.
