Abstract: The invention provides a machine tool capable of facilitating a process of switching product ejecting apparatuses. The machine tool comprises a spindle which rotates a workpiece around an axis of the spindle, an actuator which reciprocates a rod arranged parallel to the axis of the spindle, and a coupler switched between a coupling position and a standby position. The coupler connects the rod and an ejecting shaft inserted in the spindle when held in the coupling position. The coupler is not connected to at least the ejecting shaft when held in the standby position. The ejecting shaft along with the coupler is moved in the direction of the axis of the spindle according to reciprocation of the rod when the coupler is held in the coupling position.
