Wear mechanism of diamond tools generally have the following: friction and wear, abrasive broken, binders crushing and abrasive wear, surface fatigue and impact, friction and wear of abrasive grinding blunt and polished binder crushing the grit offabrasives wear due to the weakening of the strength of the binding agent to promote theabrasive disc. Different wear mechanism is different from the process, such as: micro feed grinding of structural ceramics with diamond wheel, diamond grinding wheel wear mainly three forms: friction and wear, abrasive broken and broken binder; addition Another form of wear is the binding agent is abrasive.
