First Claim
Patent Images
1. An abrasive article comprising:
- a bonded abrasive having a body including abrasive grains contained within a bond material comprising an organic material and a metal material, wherein between 82% to 97% of the abrasive grains are contained within the metal material of the bond material, and wherein the body is capable of grinding a superabrasive workpiece having an average Vickers hardness of at least about 5 GPa at an average specific grinding energy (SGE) of not greater than about 350 J/mm3 at an average material removal (MRR) rate of at least about 8 mm3/sec for a centerless grinding operation.
