ABSTRACT:
A mechanism for machining an object, such as a key blank, to a desired shape at a plurality of successive positions in an axial direction of the object, includes a holder for the object. The holder is axially movable by means of a transfer mechanism with a rotatable shaft. There is a feeder member connected to the rotatable shaft and cooperating with a clutch device axially stationary relatively to the holder. Cooperating guiding surfaces are arranged to transmit to the holder an axial movement during a limited turning of the rotatable shaft. This turning is only a small portion of a full turn of the rotatable shaft. The machining of the object takes place as a continuous guided operation during such a turning of the rotatable shaft which is separate from the turning thereof causing the holder to move axially.
