ABRASIVE GRAIN FOR MAGNETIC POLISHING

摘要

PROBLEM TO BE SOLVED: To increase the polishing accuracy by increasing the polishing amount of an article to be polished in a magnetic polishing method.

SOLUTION: An abrasive grain for magnetic polishing contains 15-85 wt.% soft magnetic ferrite component and 15-85 wt.% abrasive material component. Here, the soft magnetic ferrite component has an average particle size of 0.5-20 μm, or the ratio of the average particle size of the soft magnetic ferrite component to that of the abrasive grain for magnetic polishing is 10-5to 10-1.
