Grinding wheel and a method for manufacturing the same

摘要

The present invention provides a grinding wheel including an inner offset section and an outer flange section, capable of effectively utilizing abrasive grains without causing partial abrasion, and a method for manufacturing such a grinding wheel. The grinding wheel includes: a vibration preventing base having a supporting body and a reinforcement disposed thereon, the supporting body being formed of a supporting material made by mixing fine abrasive grains and binder, the reinforcement being provided with grooves formed in a grid-like manner to have square waves; an abrasive body formed of an abrasive made by mixing rough abrasive grains and binder; and a mandrel to be received by bores formed at central portions of the vibration preventing base and the abrasive body.
