Summary:PURPOSE:To reduce the cycle time by advancing a grinding wheel at a quick feed up to the grind feeding starting position of a place having the smallest diameter of worked places. CONSTITUTION:Feed distances S1-S3 from a clearing position Pi where a work in indexed in correspondence with places to be worked W1-W3 to grind feeding starting positions PS1-PS3 are stored in A as semiquick feed distances. A reading-out unit B reads out the semiquick feed distance S1 of the place W1 having the smallest diameter of the places which have been worked and a semiquick feed distance Sn of the place to be newly worked. The difference Si-Sn of these feed distances is calculated to obtain a semiquick feed distance Sr. A feed controlling unit D advances a grinding wheel at a quick feed by the semiquick feed distance S1 of the worked place W1 and then advances it at a semiquick feed by Sr.
