Abstract: A workpiece ejector and a method for ejecting workpieces from a turning machine such as a lathe. The turning machine has at least one spindle for receiving workpieces therethrough and at least one chuck associated with the spindle for holding a workpiece during machining operations. In one embodiment, the ejector includes a piston mounted at a location outside the spindle and proximate the chuck, the piston having a first end adapted to engage the workpiece and being movable between a first position where the first end is located outside the spindle and a second position where the first end and at least a portion of the piston are within the spindle. An actuator is operative to move the piston from the first position toward the second position. The actuator may include a mechanical spring.

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.
