ABSTRACT:
A finish broaching tool for finish cutting helical splines on the interior of an annular workpiece has a multiplicity of groups of circumferentially disposed teeth. Each group of circumferentially disposed teeth is formed on an individual wafer adapted to be mounted on the trailing end of a conventional broaching bar. The teeth of each wafer are formed on a predetermined helical angle and are adapted to helically align with the teeth of the other wafers. The wafers are sized so as to provide contact between the teeth of two or more wafers throughout substantially the entire finish broaching process.
