A key processing machine is described comprising an automatic cutter change device, a key shape learning device, a clamp component and a base. The automatic cutter change device comprises a frame structure, a cutter head, a rotary disc and a first motor unit. The rotary disc is fitted with a plurality of chambers used to accommodate the said cutter head. The cutter head is installed in the said chambers. The rotary disc and the first motor unit are installed on the said frame structure, and the said first motor unit drives the said rotary disc to rotate and further drive the cutter head on the said rotary disc to rotate. The automatic cutter change device or the key shape learning device matches the clamp component to put the original key and the key blank for processing in the clamp component, saving human resources and increasing working efficiency.

A key duplicating machine includes a clamp configured to retain a key to be copied, a reader assembly for reading cuts of the key, and a cutting tool for reproducing the cuts on a blank key. The reader includes a support bearing a feeler element with an end which contacts the cuts on the key and is movable with respect to the support along a first reference direction (Y) parallel to a resting plane. A position sensor, in electronic communication with a controller, continuously detects position changes along the first reference direction (Y) of the feeler element with respect to the support. The support or the clamp is movable along at least a second reference direction (X) that is orthogonal to the first reference direction. During movement of the support or clamp along the second reference direction, the reading end maintains contact with the cuts to follow the cut shapes.
