DIAMOND WHEEL FOR MACHINING GLASS SUBSTRATE AND METHOD OF MACHINING GLASS SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To efficiently machine the inner and outer peripheral end edges of a glass substrate and to provide a high quality surface property with less chipping by a diamond wheel having an electrodeposited diamond wheel and a metal bonded diamond wheel connected integrally with each other. ;SOLUTION: The tolerance of concentricity of the operating surface 4 of the electrodeposited diamond wheel 2 comprising a plurality of grooves for rough machining and the operating surface 5 of the metal bonded diamond wheel 3 formed of a plurality of grooves for finishing is set within 10 μm.;COPYRIGHT: (C)2003,JPO
