Tool for cutting a keyslot in a workpiece bore

摘要

A tool for cutting a keyslot in a workpiece bore for use with a numerically-controlled (N.C.) machine of the type having a plurality of tools for performing a number of machining operations on a workpiece. The tool includes a spindle which is insertable in the driving mechanism of the N.C. machine and a shaft fixed to the spindle for driving a cutter wheel responsive to spindle rotation. The spindle is received in a housing which is automatically locked against rotation relative thereto when the tool is not in the driving mechanism of the N.C. machine. An adjustable ring permits changing the cutting plane of the cutter wheel to vary the angle at which the keyslot is cut in the workpiece bore.
