CBN & Diamond wheels show its prominent capacity when it use for mass production as a grinding wheel which is capable to work both side at once. The primary application is mass production of parts requiring a high degree of straightness, flatness and perpendicularity. They are used for mirror polishing the work piece surface of compressor cylinders, the inner and outer raced surfaces of bearings, transmission gears, washers, tappet shims, vane pump vanes and rotors, precision springs, etc.
