摘要： A lathe system 1 capable of manufacturing a long product from a bar W by performing a grip change by a spindle 25 during a machining cycle, the long product being of a length exceeding a movable range of the spindle 25, the spindle 25 releasably gripping the bar W and moving in a Z 1-axis direction of the bar W. The lathe system 1 includes a pusher 44 capable of moving in the Z1-axis direction together with the bar W. The lathe system 1 further includes a bar length shortage prior determination unit 20b that determines whether the pusher 44 is in a position permitting the grip change to be performed during the machining cycle. The determination is made prior to the start of the machining cycle.

摘要： 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.
