Abstract

PURPOSE:To enable a device to obtain a low priced guide reducing an inferior rate of break or the like and eliminating a trouble of blocking or the like, by using ceramics of good wearing resistance for an upper and a bottom guide itself. CONSTITUTION:A guide, using alumina, silicon nitride, zirconia, silicon carbide, etc. as a ceramics material and placing these material dust in a metal mold to be formed by pressure molding thereafter to be taken out from the mold then applying firing at a high temperature, polishes after the firing a point end part 19 brought into contact with a wire electrode, obtaining a mirror surface. While the point end part 19 is polished until it obtains a specified dimensional accuracy. And the guide, when it performs electric discharge machining by using guides 5, 6, can be mounted in a nozzle as in the past because of equal shape, while the guide, providing no edge of break or the like in a contact part with the wire electrode, never cuts a surface of the wire electrode, preventing blocking from being generated even if machining is continued for a long time.
