CONSTITUTION:Width of a guard bar 4 is set to length of a work W, and the work W is sent out from a shelve 1 and pushed up to the grinding table through a conveyor 14, and at this time, the conveyor 14 stops. When a grinding belt 28 was lowered, a rolling receptacle 21 and the belt 28 start rotationg for a prescribed time preset to grind outer circumfernce of end of the work W. When the prescribed time has passed, the rotation is stopped, the grinding belt 28 is raised, the conveyor 14 is started, the processed work is pushed by a pushing fork 19a and fall onto a receiving frame 3, and at the same time, another work is pushed upt the grinding table. |
