ABSTRACT:
In a travelling wire EDM apparatus having orientable swivelling wire guide and support members, or wire guide heads, the orientation of each wire guide head is effected by a pair of hydraulic slave cylinders each connected to a master cylinder. Each master cylinder has an input member displaceable along one direction and the desire inclination of each wire guide head is the resultant of the composite motions of the output members of the corresponding slave cylinders.
