To correct yawing generated at a table, in a machine tool in which the table which moves in a direction orthogonal to one axial direction is mounted to a saddle which is movable in the one axial direction.

A pair of linear motors 7 moving in the X-axial direction with a prescribed interval therebetween in the Y-axial direction are arranged on the saddle 3, and a Y-axis guide 8 is attached so as to be parallel with the Y-axial direction. The table 4 is connected to the Y-axis guide 8 so as to be fixable with respect to the X-axial direction and turnable at a prescribed amount around a Z-axis passing through the table 4. Positions in the Y-axial direction at both ends of the table 4 in the X-axial direction are detected, and a position of each linear motor 7 is controlled on the basis of the detected positions.
