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.
