Patent ID: 11484947

Abstract:
A machine tool includes a spindle headstock having a main spindle, a spindle headstock having a main spindle with a Z3 axis parallel to an axis center direction of the main spindle, a turret that moves relative to the spindle headstocks, and a controller that superposition-controls the spindle headstock with movement of the turret as a standard, wherein the turret is movable in directions of an X axis and a Ys axis that are orthogonal to a Z axis and intersect with the Z axis at an angle except for the right angle, and the controller moves the turret in a direction of a Y axis different from the Ys axis and the X axis by combining movement in the direction of the Ys axis and movement in the direction of the Y axis, and regulates, in the superposition control, the movement of the spindle headstock in the X axis direction associated with the movement in the Y axis direction.
