ABSTRACT:
A method and apparatus for grinding a workpiece which is supported for rotation about a first axis with a first grinding wheel supported for rotation about a second axis and a second grinding wheel supported for rotation about a third axis. The first grinding wheel engages with the workpiece in a location which is substantially diametrically opposed to the location at which the second grinding wheel engages with the workpiece. Control means are disclosed for controlling the radial grinding force imparted to the workpiece by the first and second grinding wheels so that the force imparted to the workpiece from the first grinding wheel is substantially equal and opposed to the force imparted to the workpiece by the second grinding wheel to prevent distortion of the workpiece.
