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. |
