  • Patent number: 5333657
    Abstract: Apparatus for turning and milling a workpiece includes a frame having a chuck and a spindle spaced laterally of the chuck mounting respective opposite ends of the workplace for rotation generally about its longitudinal axis. A carriage mounting the milling device is supported by a rail on the frame for movement generally side-to-side of the frame and longitudinally of the workpiece. A first variable speed electric motor operatively connected to the chuck for driving the rotation of the workpiece about its longitudinal axis is controlled by a first control, which is used to selectively set the rotational speed of the workpiece.
