Abstract
A wire direction changer assembly is disclosed for installation in the wire path system of a wire electrode spark erosion machine with a wire entrance port, a wire discharge port, an essentially tube or tunnel wire guide channel connecting to both ports along a curved path; and a suction nozzle disposed in the region of the wire discharge port for providing a fluid flow through the wire guide channel. These features provide an exceptionally trouble-free fluid-supported wire direction changer of the electrode wire, while at the same time ensuring trouble-free automatic wire threading.
