PURPOSE: A double injection nozzle for a wire discharge machine is provided to save replacement costs generated by damages of a nozzle according to the surface structure without changing a processing condition according to the surface structure. CONSTITUTION: A double injection nozzle for a wire discharge machine comprises a power supply guide (10), a guide block (20), a wire guide (30), an inner nozzle (40), and a nozzle support unit. The wire guide guides a wire (11) to rapidly convey downwards through a nozzle hole (32). The inner nozzle is formed to be vertically moved through a workpiece (W) to process uniformly. The inner nozzle is mounted on an outer circumferential surface of the nozzle support unit supporting the inner nozzle. |
