Producing teeth with curved flanks on conical surface of blank - using cutter with teeth rotating in circular path whose axis is offset from and inclined to axis of rotating blank

摘要

The equipment machines teeth (2) with curved flanks on the conical end face of the workpiece blank (1). The workpiece rotates about its axis (A) and is fed along its axis towards the cutting tool (3). At the same time the cutting tool, which is in the form of a ring with a number of teeth (4) spaced around the end face, rotates about an axis (B) which is offset from the workpiece axis (A) and inclined to it by the angle beta. The curvature of the tooth flanks can be varied by adjusting the rotational speeds of the workpiece or cutting tool. USE/ADVANTAGE - Accurate, low-cost production of teeth with curved flanks on conical surface of blank.
