ABSTRACT:
A wire guide apparatus for the wire electrode electric spark forming machine utilizes the flow of compressed air for feeding the used wire into a cutting apparatus that is operated in combination with the wire guide apparatus. The wire guide apparatus includes a guide tube 1 for taking in the used wire from the electric spark forming machine and a compressed air supply section 2. The guide tube 1 has a funnel-shaped wire introducing port 3 formed at the upper end and a wire discharge port at the lower end. The compressed air is injected into the guide tube 1 from the fluid injection path 5 formed in the circumferential wall 1a of the guide tube to smoothly guide the wire 12 from the wire introducing port 3 to the outside of the wire discharge port 4.
