Key-cutting machine

Abstract

A machine for cutting flat keys having extending tumbler-receiving recesses includes a mount for a key blade blank, a mount for a cutter, mechanism mounting the blank mount and the cutter mount for movement relative to each other for cutting a longitudinal tumbler-receiving recess in a blade blank mounted on the blank mount with a cutter mounted on the cutter mount, and mechanism mounting the blank mount and the cutter mount for adjustment of their relative positions to adjust the position of the cutter transversely with respect to the blade blank, whereby a plurality of tumbler-receiving recesses may be cut in the blank thereacross. A holder for the blade blank is pivotally mounted on the blank mount for 180-degree rotation about the longitudinal axis of the blank, whereby the recesses may be cut in opposite sides of the blank.
