  • Patent number: 7513181
    Abstract: A device for effecting an unloading operation of a workpiece with respect to a machine tool. The device includes a non-rotating dump tube having one end adapted for communication with a machine tool and a sidewall defining an opening for discharging a workpiece, a vacuum chamber enclosing the opening in the sidewall and including a workpiece outlet, the chamber configured to receive a workpiece from the dump tube, a door selectively sealingly engaged with the workpiece outlet, and configured to allow the unloading of a workpiece, and a source of vacuum coupled to the vacuum chamber and configured to draw a workpiece through the dump tube and into the vacuum chamber for unloading. A coupling may be disposed between an unloading device and a machine tool to allow the machine tool to operate at increased rates during an unloading operation.

  • Patent number: 6978706
    Abstract: A spindle liner for a turning machine has an elongated polymeric member sized to fit within the inner diameter of a spindle and further has a bore through the polymeric member sized and shaped to receive a given size bar stock. The spindle liner may be installed within a spindle and bolted to a spindle flange by an adapter fixed to the spindle liner so that the spindle liner rotates with the spindle. The spindle liner attenuates noise and vibration of the rotating bar stock and eliminates whipping of the free end of the bar stock.

  • Patent number: 6243019
    Abstract: A device for effecting at least one of a loading and unloading operation of a workpiece with respect to a machine tool. The device includes a base adapted to be mounted adjacent the machine tool and a tubular member. The tubular member includes an inner chamber and an elongate opening communicating with the inner chamber for receiving the workpiece. The inner chamber has one end adapted to communicate with a spindle of the machine tool and the tubular member is mounted for rotation with respect to the base. A sealing member is mounted for selective removal and sealing engagement with respect to the elongate opening and a source of pressurized air communicates with the chamber for moving the workpiece in at least one direction within the chamber when the sealing member is in sealing engagement around the elongate opening.
