A blind spline broaching machine for machining splines as well as sprockets, keyways, gears, cams and contours on workpieces, such as shafts. The blind spline broaching machine of the preferred embodiment has dual rams reciprocable relative to a rotary dial. The rams hold a corresponding pair of workpieces, while the rotary dial supports one or more broaching tools. The rotary dial is rotatable to index the workpieces to and from the rams. The blind spline broaching machine also incorporates a part moving unit on its periphery, which enables the use of a single loading/unloading station at which workpieces are alternately loaded onto and unloaded from the rotary table. Because the workpieces are loaded and unloaded from the same location on the periphery of the blind spline broaching machine, the side of the blind spline broaching machine opposite the loading/unloading station remains open to permit ready access to the tooling and the interior structure of the blind spline broaching machine. In addition, only one conveyor system is required to transport workpieces to and from the blind spline broaching machine. As a result, the complexity of and the floor space required for the blind spline broaching machine is substantially reduced.
