the lower slide of a cross slide table lateral displacements of the plate cause the unitary assembly to orient itself under the action of a pair of fingers mounted on the plate co operating each with a ramp mounted on the cross slide table such as the unitary assembly constantly remains coaxial with the electrode wire application_number US 39529782 A description fig1 of the drawing illustrates an electrode wcrkpiece 1 in the process of being cut by means of an electrode wire 2 supported and guided by a pair of guide members 21 and 22 one disposed on one side and the other on the other side of the workpiece 1 the electrode wire 2 passes through a nozzle 3 such that the nozzle surrounds the wire the nozzle 3 has a dielectric fluid inlet 4 leading into an annular chamber 5 surrounding a channel 6 through which passes the electrode wire 2 the dielectric fluid introduced into the annular chamber 5 flows through an annular outlet such as to form a jet 8 surrounding the wire and directed towards the machining zone 9 between the electrode wire 2 and the workpiece 1 the nozzle 3 and the wire guide member 21 form.
