REMOVING METHOD OF MAGNETIC DISK BOARD AFTER POLISHING WORK

摘要

PROBLEM TO BE SOLVED: To provide a method for easily removing a magnetic disk board after polishing work from a surface of a polishing grinding wheel. SOLUTION: In a method for removing a magnetic disk board 1 having both surfaces polished by an upper side polishing grinding wheel 2 and a lower side polishing grinding wheel 3 from a surface of the respective polishing grinding wheels after polishing work, after separating the upper side polishing grinding wheel 2 from the lower side polishing grinding wheel 3 while sucking/holding the magnetic disk board 1 by reducing pressure from the inside of an air vent 4 arranged on a surface of the upper side polishing grinding wheel 2, the magnetic disk board 1 is dropped on a prepared receiving pan 6 by blowing off air from the air vent 4 to solve the subject.
