Abstract: The wear of a brazed diamond wheel with diamond grits precovered by brazing alloy was investigated in comparison with a traditional brazed wheel whose grits were without coverings. The two wheels were brazed in vacuum. The wear of the two wheels was tested through grinding of granite, during which grinding forces were measured and the wear states of diamond grits were observed. It is shown that the brazed diamonds precovered with brazing alloy exhibited stronger self-sharpening ability and rupture resistance. Subsequently, the wheel with precovered diamonds performed lower grinding force and better wear performance.
