ABSTRACT:
A wire guidance arrangement for guiding a wire electrode of a spark erosion machine has several replaceable wire guides, which are mutually spaced to thereby form individual erosion zones. The individual wire guides are held by spring tension in corresponding openings of a guide plate, which rest on a base block. The common plane of the guide plate and the base block forms a reference plane on which are axially centered the undersides of wire guidance members of the individual wire guides. Even in the case of a greater wire electrode fixing length, this always ensures a satisfactory guidance of the wire electrode. In addition, the individual wire guides can be simply replaced without any adjustment being necessary.
