Abstract

PURPOSE: To correctly grind gead shafts having longer shaft part by elevating a supporting element after detecting the transfer to through-feeding grinding, and by supporting the working material heat part side from lower side by the supporting element, and by shifting the supporting element in synchronization with through- feeding speed.
CONSTITUTION: In transition to through-feeding grinding after the completion of feeding grinding, a sensor 11 detects the transition, and the driving of a vertical movement device 9 elevates a supporting element S, and then the supporting element S supports the axis part of a material to be worked. Then, accompanied with the transition of the material to be worked, a sensor 10 detects the slip-off of the material to be worked from the heat part intermediate large diameter part 1', and drives a slide operating mechanism 8, and shifts the supporting element S in the same direction to the through-feeding direction 3 with the same speed to the material to be worked, and the part close to the head part of the material to be worked is supported by the supporting element S described above until the completion of through-feeding grinding. Thus, even the head shafts having longer shaft part than grindstone width can be ground correctly over whole length.
