PCT No. PCT/EP84/00095 Sec. 371 Date Dec. 17, 1984 Sec. 102(e) Date Dec. 17, 1984 PCT Filed Apr. 4, 1984 PCT Pub. No. WO84/04067 PCT Pub. Date Oct. 25, 1984.A machine bed for machine tools having two guides lying in separate planes each having two guide ways, namely an approximately horizontal main guide and an additional guide at an angle thereto, in which at least the guide ways of the main guide lie on intersecting tangents or parallels thereof, of a circle whose center is the same as the workpiece and/or tool center of rotation of the machine. To prevent instability of the component groups on the main guide, even in the case of workpieces of great weight and of the occurrence of high machining forces, it is proposed that the intersection M of the perpendiculars of force N-1, B-2, resulting upon the thrust of the component groups on the main guide, be offset from the center of gravity S of a workpiece 16 being machined, such that cumulative torques M-1, M-2, resulting on the basis of the workpiece weight and the machining force FR of the workpiece 15, which will force the component groups carried on the main guide 11, 12, against the rear guide way 12 remote from the operator side A.
