MACHINE TOOL

PROBLEM TO BE SOLVED: To provide a machine tool which moves a moving body in an optimum state according to an axial feed mode. SOLUTION: The machine tool is a vertical machining center formed of a bed 10, a column 20 erected on the bed 10, and a spindle head 30 vertically movably supported on a front surface of the column 20. The machine tool includes a saddle 40 on a front side of the column 20 arranged on the bed 10, in a manner movable in a Y axis direction, and the saddle 40 has a table 50 mounted thereon in a manner movable in an X axis direction. The saddle 40 and the table 50 are guided in their moving directions by static pressure slide guideways, respectively. When the saddle 40 and the table 50 are moved in a "cutting feed mode", lowly pressurized oil is automatically fed to the respective static pressure slide guideways, and when they are moved in a "rapid traverse mode", highly pressurized oil is automatically fed to the respective static pressure slide guideways.
