PURPOSE:To permit automatic chamfering and improve working accuracy by feeding the work pushed-out onto a guide board from work holding devices by a pusher, into between a guide and a plurality of one-side-tapered grindstones by the pusher and executing chamfering. CONSTITUTION:Works 5 are set in superposed state onto work holding devices 6, 6a, and 6b, and a pusher 3 is advanced by driving a cylinder 1, and the work 5 in the lowermost part of the work holding device 6 is pushed-out towards a guide base 8. Then, the cylinder 1 restores the pusher 3 to the original position and pushes-out the next work 5 from a container 6. Then, the work 5 on the guide base 8 is shifted in X direction by inclination, and a cylinder 2 is driven to push-out the work in (y) direction by a pusher 4, and the work 5 is pushed into between the grindstones 10 and 10a and the guide 8. Then, the cylinder 2 restores the pusher 4 to the original position. Then the both edge surfaces of the work 5 can be chamferred at the same time by the revolution of the grindstones 10 and 10a by the start of motors 9 and 9a and the weight of the motor. Further, the shaft of the grindstone can be adjusted according to the variation of the dimension of the work.
