Abstract
The invention relates to improvements in a tilting mechanism for a saddle swivel head for a double housing type machine tool. The saddle swivel head 13 is provided at the sides thereof in the tilting direction with hydraulic cylinders 18R, 18L, to which is connected a hydraulic piping system 19 for giving swivel balancing pressures and back pressures when the swivel head 13 is tilted by a predetermined angle by a tilting driving mechanism. The saddle swivel head 13 is tilted while providing swivel balancing pressures to the hydraulic cylinders 18R, 18L, and after tilting the head by the predetermined angle, back pressures are applied to the hydraulic cylinders 18R, 18L to compensate for a tilting moment of the saddle swivel head 13.
