Abstract:
A resin bonded grinding wheel suitable for grinding polycrystalline diamond compacts is disclosed. The resin bonded grinding wheel uses a high concentration of diamonds based on a volume percent along with a mixture of hard and soft filler particles to effectively grind the polycrystalline diamond compacts while eliminating or reducing the need to continuously dress the outer surface of the resin bonded grinding wheel.
