Abstract: A machine tool comprises a main spindle, a tool post body provided with a first tool mounting part and a second tool mounting part facing each other with a workpiece inbetween in a predetermined facing direction, and a tool post body driving unit for moving the tool post body in at least the facing direction. The tool post body comprises a first tool post unit provided with the first tool mounting part, a second tool post unit provided with a portion of the second tool mounting part with a relative interval with respect to the first tool post unit in the facing direction kept constant, a third tool post unit provided with the remaining portion of the second tool mounting part with a relative interval kept variable; and a relatively-driving unit for moving the third tool post unit in the facing direction with respect to the first tool post unit.

Abstract: A technology capable of improving machining performance of a lathe is provided. A first attaching position and a second attaching position are adjacent to each other in a tool unit attaching direction perpendicular to a spindle axis direction. A second tool unit attached to the second attaching position is of a shape avoiding an area that a spindle possibly occupies relatively with respect to a first tool unit working on the workpiece. When a rotary tool unit is attached to one of the first attaching position and the second attaching position, a machining point of the second tool unit working on the workpiece is deviated to the side of the spindle in the spindle axis direction from the rotational center of the rotary tool unit across the turret surface.

Abstract: A machine tool capable of restraining dirt on the footstool and improving setup efficiency. The machine tool includes a machine body having a splash guard surrounding a machining area and a door capable of closing an opening of the splash guard. A footstool is kept mounted on the machine body changeably in place with respect to the machine body. The footstool kept mounted on the machine body is capable of being in a place on an outside of the machine body when the door is closed. The footstool kept mounted on the machine body is capable of being brought to a setup place inside the machining area from the outside of the machine body through the opening when the door is open.

Abstract: A technology capable of downsizing the lathe is provided. The lathe comprises a spindle which rotates a workpiece on a spindle axis, a turret head, and a tool unit switching driving unit. The turret head has a plurality of turret surfaces to which a tool unit is radially attached around an indexing axis. To at least part of the turret surfaces, the tool unit is attached in a plurality of attaching positions provided in an indexing axis direction along the indexing axis. The tool unit switching driving unit rotates the turret head on the indexing axis and moves the turret head in the indexing axis direction to switch the tool units for use to machine the workpiece.
