Title: A grinding wheel having a grinding segment holder
IPC: B24D5/06
Filed: 2020-05-12
Abstract: The present invention relates to a grinding wheel in which a plurality of grinding segments (3) having grinding tips attached thereto are respectively mounted on holders (2) disposed at ends of a disk-shaped grinding wheel (1) near the outer peripheral surface thereof to be spaced apart from each other. The holders (2) fixed to the grinding wheel are provided to mount the grinding segments (3) on the grinding wheel (1).
