Abstract
A method of grinding a superabrasive workpiece includes placing a bonded abrasive article in contact with a superabrasive workpiece, wherein the bonded abrasive article comprises a body including abrasive grains contained within a bond material, and the superabrasive workpiece has an average Vickers hardness of at least about 1 GPa, and removing material from the superabrasive workpiece 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.
