ABSTRACT:
Disclosed is an improvement in method for both dry grinding and wet grinding a workpiece selected from cemented tungsten carbide and combinations of cemented tungsten carbide and steel with a single resin bonded grinding element having metal-coated diamond particles embedded in the grinding surface thereof. Such improved method comprises providing coated diamond particles useful for both dry grinding and wet grinding operations which comprises diamond coated particles coated with two layers of metal, the inner layer consisting of between about 40% and 130% by weight of said diamond particle of nickel and the outer layer consisting of between about 20% and 70% by weight of said diamond particle of silver, wherein the total weight of both said silver and nickel coatings does not exceed above about 200% by weight of the uncoated diamond particle.
