Procedure to rectify a tool for precisely machining the teeth of a cogwheel

摘要

Procedure for grinding a tool (1) designed to precisely machine the teeth of a cogwheel, which has a cogwheel (6) that engages with the cogwheel to be machined, by means of a correction wheel (3), in which the cogwheels (6 ) of the tool (1) to be ground and of the grinding wheel (3) are meshed together, in which the grinding wheel (3) and the tool (1) to be ground are rotatably driven in each case by means of a drive own in each case around an axis of rotation (B, C), and in which adjustment drives are provided to adjust the relative position of the tool (1) to be ground and grinding wheel (3) at least in the direction (direction Z) of the axis of rotation (C) of the grinding wheel (3) and in one direction (X direction) oriented transversely to it, characterized in that the width (BA) of the teeth (16) of the grinding wheel (3) ), which are engaged with the tool (1) to re ctify, corresponds to a maximum of one fifth of the width (BW) of the tool (1) to be ground, so that the grinding wheel (3), to pass through the width (BW) of the tool (1) to be ground, is you have to move a length (L) in the Z direction that corresponds to a multiple of the width (BA) of the teeth (16) of the grinding wheel (3),
