An improved spindle assembly for a single or a multiple spindle machine is disclosed. An outer tubular member is mounted for rotation by the spindle machine. An inner shaft is positioned within the tubular member and a collet is movable between a locked and an unlocked position. A workpiece can be removed from the unlocked collet by high pressure liquid from the inner shaft. In one embodiment the inner shaft is rotated independently from the tubular member and is also axially reciprocable. A tool mounted on the inner shaft provides for interior machining at the same time as an exterior operation is being performed. In another embodiment the collet remains axially stationary.
