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.
