ABSTRACT:
A control device40controls the grinding processing at a processing portion of a work W so as to shift to the last precision grinding step from a rough grinding step through a middle grinding step and a finishing grinding step. When the grinding in each step is carried out, two processing portions are measured, and then, it is determined whether or not one or both measurement values attain to a predetermined value that has been determined in advance when each step is finished. When a processing time difference t is generated between the processing portions, by increasing or decreasing the feeding amount per unit time in a next step, the processing time difference is eliminated. Thereby, the finishing grinding step just before the last steps of the both processing portions are simultaneously finished.
