70488-7 ABSTRACT OF THE DISCLOSURE A machine tool comprises an upstanding column, a tool- driving unit vertically movable relative to said column, and a pair of guide rails laid on a front surface of said column to extend vertically thereon and horizontally spaced apart from each other for guiding the upward and downward movement of the tool- driving unit. The tool-driving unit includes a lift frame on the guide rails and a tilting-type turret head which is supported on a front surface of the lift frame and is rotatable about an axis inclined to the longitudinal direction of the frame on a horizon- tal plane. One of the pair of guide rails is relatively disposed ahead of the other guide rail, so that the individual guide rails both assume positions close to the turret head thereby to minimize the amount of overhanging of the tool-driving unit.
