PROBLEM TO BE SOLVED: To provide a machine tool in which a relative arrangement relationship between a component member for centering measurement and a component member for workpiece machining can be disregarded, the reliability of measurement results is enhanced by preventing the occurrence of an measuring error, working time is shortened by allowing the replacement of component members during the centering measurement and the versatility of the machine tool is enhanced. SOLUTION: In the machine tool, a gate-type column 13 is set over a reciprocative table 12, and a machining device head unit 15 which is movable on a machining device cross rail 14 extending in a direction orthogonally crossing a reciprocating direction of the table 12 and has a shaft section 15b for vertically displacing a machining head 15c for the workpiece machining is arranged on one surface of the column 13. Further a measuring instrument head unit 17 which is movable independently from the machining device head unit 15 on a measuring instrument cross rail 16 extending in a direction in parallel with the machining device head unit 15 and has a shaft section 17b for vertically displacing a measuring head 17c is arranged on the other surface of the column 13.
