摘要：
In a grinding machine, a rest apparatus is advanced to move a workpiece toward a grinding wheel being in a stationary condition after a preliminary grinding operation. After a predetermined amount of advancement of the rest apparatus, the grinding wheel is again advanced to grind the workpiece while the rest apparatus is stationary until the workpiece deviates from engagement with the rest apparatus, whereby after a final grinding operation, the workpiece is ground at the true center thereof so as to be in true roundness and with good concentricity.
