Patent ID: 6847002

Claim:
A microelectrode machining device, comprising: a platform, fixed on an electrical discharge machining table; a wire supply mechanism, disposed on the platform for supplying wires needed by an electrical discharge machining process; a wire guide, disposed on the platform, and having a slide arranged thereon and a groove arranged at a position corresponding to the middle of the slide; and two electric conductor elements, disposed respectively at the side of wire guide on the platform, and both the altitudes of the bottom thereof are lower than that of the two ends of the slide of the wire guide, in respective; wherein, the wire supplied by the wire supply mechanism first passes through the bottom of the electric conductor element, and enters the slide by one end thereof, that is, a wire entrance, and exits the same by another end thereof, that is, a wire exit, and then passes through the bottom of another electric conductor element, such that the wire is subject to a minute downward suppressing force which cooperates with the slide of the wire guide for enabling the wire to pass through the wire guide smoothly.
