Abstract
A lathe includes a spindle rotatable on a spindle axis, a tool post to which a tool is attachable, an X1-axis ball screw extended in an X1-axis direction perpendicular to the spindle axis and capable of moving the tool post in the X1-axis direction, and an X1-axis support bearing provided on an end of the X1-axis ball screw with respect to the X1-axis direction to restrict movement of the X1-axis ball screw in the X1-axis direction. The tool post is provided with an X1-axis ball screw nut engaged with the X1-axis ball screw. The X1-axis ball screw nut is movable in the X1-axis direction according to rotation of the X1-axis ball screw. The direction that the X1-axis ball screw nut approaches the X1-axis support bearing faces the same direction as the direction that the tool cuts into the workpiece.
