摘要： A multi-axis turning center for turning operations includes a machine body, a tool rest means for holding a tool, a first headstock for holding a workpiece, and a second headstock disposed in confronting relation to the first headstock, for holding a workpiece. The second headstock has a front chuck and a rear chuck for gripping respective workpieces. The second headstock performs a workpiece changing function by swiveling about a central axis. The multi-axis turning center is capable of automatically changing the workpieces by itself while it is carrying out a machining process, without the need for a workpiece changer. The multi-axis turning center does not need to stop its machining process for changing workpieces, resulting in an increase in the utilization ratio thereof.

摘要： To provide a machine tool in which a workpiece can be delivered to/from a first and a second spindle headstock without any increase in front/back direction dimension of a machine main body. A second spindle headstock 4 is capable of moving to a position for workpiece delivery to/from a first spindle headstock 3 so as to be close to or to abut on the first spindle headstock 3. When the second spindle headstock 4 is positioned at the workpiece delivery position, a tool post 5 is positioned right under the first spindle headstock 3 so that its cutting point “c” is positioned vertically under an axis “a” of the first and second spindle headstocks 3, 4.
