The time to grind a workpiece (82) can be reduced by selecting a grinding wheel whose width is not substantially greater than wheel strength consideration require, and which may therefore be less than the axial length of the region to be ground. It is especially beneficial in a grinding machine (68) to employ two narrow grinding wheels mounted for independent movement towards and away from a workpiece (82). The wheels can be applied to plunge grind axially separated regions of a cylindrical portion of a workpiece, thereby enabling the machine to grind a range of axial lengths up to a length not exceeding a sum of the two wheel widths. <IMAGE> |
