Abstract

Method and apparatus for a cutting key having an elongate bit in which the bit is urged against the working edge of a cutting or grinding tool such that the bit moves with respect to the working edge during the cutting or grinding operation. A preferred embodiment comprises a series of spaced parallel saws (7) whose cutting edges are independently adjustable with respect to the axis of a key bit, inserted in a slot (3) of a rotatable barrel (2), by means of a cam member (12) which cooperates with a bearing member (17) engaging with the respective saw (7). Each saw (7) is biassed against its respective member (17) by a pair of spring-loaded bearings (8, 8') at respective ends of the saw and each saw is reciprocably driven by a drive member (10), the return stroke of each saw (7) being effected by a freely reciprocable but spring biassed member (10'). <IMAGE>
