An orientable unitary assembly for the support and guide member for the electrode wire of a travelling wire EDM apparatus, the assembly also comprising a nozzle supplying a machining fluid jet coaxial to the electrode wire. The assembly is supported by a cross-slide table permitting to incline the axis of the wire relative to a wire support and guide member disposed on the other side of a workpiece. The displacements of the slides of the cross-slide table are effected by leadscrews each driven by a servo motor, and the orientation of the assembly is controlled by the same servo motors via second screwthreads of different pitch each displacing a nut which, through a push-rod, controls the inclination of the assembly.
