    • A machine tool includes a table, a main spindle unit, a cross rail, a plurality of columns and a plurality of supportive transfer mechanisms. The plurality of columns vertically guide the cross rail, the columns being erected at positions on opposite sides of the table and on front and rear sides of the center of gravity of the main spindle unit on each side of the table. The supportive transfer mechanisms vertically move the cross rail while supporting the cross rail. The cross rail has a pair of supporting portions for supporting front and rear portions of the main spindle unit located frontward and rearward with respect to the center of gravity of the main spindle unit, respectively, and a plurality of through holes through which the columns are passed vertically.
