ABSTRACT:
The invention relates to a machine for automatically duplicating flat keys, using a model key which is presented to a feeler and a rotating cutter that engages a key blank in accordance with the teeth profile of the model key. The machine comprises a housing with a fixed frame, a movable support carrying the key-clamping jaws, and two motor-operated control cams which impart to said support two orthogonal, reciprocating movements by which the key blank is urged against the cutter and passed along the same with different speeds for the approach movement and for the milling operation.
