    • On a frame, a headstock (5) and a tool rest (6) are provided being free to relatively move so as to perform machining operations. The headstock (5) is rotatably provided with spindle (6). The spindle (6) is provided with a workpiece gripping means (6a). One or more than one bar supporting means (27) for movably supporting a bar stock (50) in a predetermined feeding direction are provided at a predetermined position with respect to the spindle (6). A cutting means (40), for cutting the bar stock (50) supported by the bar stock supporting means (27) at a cutting position on the feeding direction side to the bar supporting means (27), is provided. A workpiece carrying means (7) is provided being free to move relative to the headstock (5) so as to deliver the workpiece (50a) produced by cutting of the bar stock (50) with the cutting means (40) to the workpiece gripping means (6b) of the spindle (6) from the workpiece gripping means side to the spindle.
    • 在框架上,提供主轴箱和工具架以自由地相对移动以进行加工操作。 主轴箱可旋转地设有主轴。 主轴设有工件夹紧装置。 在相对于主轴的预定位置处设置有用于在预定进给方向上可移动地支撑杆坯的一个或多个杆支撑装置。 提供一种切割装置,用于在向条形支撑装置的进给方向侧的切割位置处切割由条形支撑装置支撑的条形坯料。 设置有相对于主轴箱自由移动的工件承载装置,以便将通过切割装置切割杆材所产生的工件从工件夹持装置侧输送到主轴的工件夹持装置。
