To manufacture a precise roller of an elastic body by suppressing the run-out of the roller of the elastic body by reducing its deflection through reducing the grinding resistance, and further by eliminating the generation of chatter.
In the plunge-cut grinding method for grinding the outer peripheral surface of the roller 101 of the elastic body by means of a cylindrical grinding wheel 22, when the grinding is carried out by bringing the grinding wheel 22 turning in the state facing to the roller 101 into contact with the roller 101, the variation of the load caused by the contact of the grinding wheel 22 with the roller 101 is detected by means of a sensor which works interlocking with the variation of the load, and the advance and withdrawal of a grinding wheel head 20 are controlled.
