US Patent 7115019 Grinding method and grinding machine

In a grinding machine, a generally cylindrical workpiece having at least first and second grinding areas is ground by use of a grinding wheel supported by a wheel head. The first grinding area is first ground such that power consumed by the grinding machine is maintained at a first level. After completion of grinding for the first grinding area, the grinding wheel is indexed to the second grinding area by moving the wheel head such that the power consumed by the grinding machine is maintained at a second level higher than the first level. After completion of the indexing operation, the second grinding area is ground in the same manner as the first grinding area.
