ABSTRACT:
A machine tool more particularly for drilling and milling, possesses a machine bed, on which a power driven longitudinal slide is adapted to run horizontally on rails. A machining head having a rotary drive device for at least one table forming part of said head, is power moved on the longitudinal slide in at least one further direction of movement. The machine bed possesses two spaced lateral walls, whose intermediate space is designed to serve as a machining zone for receiving at least one work holding means. On the two lateral walls two parallel guide rails are arranged for the longitudinal slide, a third guide rail being arranged with an offset in the longitudinal direction between the two other guide rails. The longitudinal slide is guided using three guide elements on the three guide rails, the power drive being at or adjacent to the central guide rail. On this arrangement a clamping yoke of relatively light design may be employed, which only requires one central drive. Transverse forces caused by twisting in the case of eccentric loading act perpendicularly on the guide elements, which are accordingly better able to withstand the forces.
