Abstract
A key duplication system employs a modular key duplication attachment in combination with a high-speed, rotary powered tool and a profiled abrasive cutter. The attachment comprises a base, a carriage assembly movable relative to the base, a profiled stylus secured to the base, a first clamping vise for retaining a specimen key at a fixed (i.e., stationary) position relative to the carriage assembly and a second clamping vise for retaining a key blank at a fixed position relative to the carriage assembly. When so-retained, a bottom flat surface of the specimen key and a bottom flat surface of the key blank rest in a common working plane and the tip of each key is separated by a first distance. The cutter and stylus are aligned and secured to the base such that movement of the carriage, relative to the base, simultaneously brings them both into contact with appropriate surfaces of the key blank and the specimen key, respectively.
