ABSTRACT:
A key duplicating machine having a key clamping assembly for supporting a key blank and a customer key to be duplicated, a key cutter assembly having a cutter wheel for cutting a pattern on the supported key blank and a follower for tracing a tooth patter on the supported customer key, a housing having a front wall, a top wall and a chip collection drawer lcoated below the front and top walls, the key clamping assembly being mounted on the front wall and the key cutter assembly being mounted on the top wall such that no obstructions exist between the key cutter assembly and the chip collection drawer located below the top wall, so that chips formed from a key cutting operation by the key cutter assembly fall unimpeded to the chip collection drawer, and surfaces which may collect the chips are minimized. In a preferred embodiment, a motor driven cam assembly actuates the key cutter assembly and a finger for locating the key blank and customer key of the key clamping assembly, the cam assembly being mounted on a rear portion of a top wall behind a midwall, and the midwall acts as a barrier to prevent chips produced during a cutting operation from progressing to the cam assembly. The key clamping assembly and key cutter assembly each include modules which accommodate keys for both single and simultaneous double key cutting.
