摘要： A workpiece ejecting device for a machine tool, in which the ejecting bar cannot be rotatably driven at the time of high velocity rotation of the spindle to thereby prevent occurrence of vibration, noise and frictional heat, and so that the workpiece can be ejected smoothly. The workpiece ejecting device comprises: a front bearing unit installed at an inner peripheral surface of a front end portion of the drawing tube; an ejecting cylinder located behind the chucking cylinder and installed directly on an axial line identical with that of the front bearing unit, and an ejecting rod, wherein the ejecting rod is provided at a center axis thereof with at least one fluid passing opening through which fluid for removing alien materials is supplied, and a front end of the ejecting rod is installed to be supported by the front bearing unit.
