Abstract: An apparatus for primary and secondary machining of a workpiece segment of a length of bar stock includes a lathe for primary machining of the workpiece and a rotary transfer machine for secondary machining of the workpiece. The lathe has a sliding headstock for rotating and advancing the bar stock and a rotatable drive collet for holding the bar stock. A rotatable guide bushing is aligned with the drive collet for supporting and clamping the bar stock. A tool holder is positioned adjacent to the guide bushing for holding one or more tools for primary machining of the workpiece. The rotary transfer machine receives the workpiece via a fixture aligned with the lathe and performs secondary machining of the workpiece.
