A wire guiding device for enabling the guiding of a wire electrode at an angle with respect to the normal straight line of wire travel. The wire is placed at an angle by the upper and/or lower wire guide assemblies being displaced from one another. The wire guiding device includes a guide member having a bore that increases in diameter toward a first opening and wherethrough the wire electrode is received. The guide member is pivotally supported and is allowed to pivotally move about a point along the longitudinal axis of the bore about two axes of rotation. Pivotal movement of the guide member is caused by the wire electrode traveling at an angle between the guide assemblies with respect to the normal straight line of wire travel. Fluid under pressure is caused to be directed through the guide member and out toward a workpiece substantially surrounding the wire electrode for flushing the workpiece cutting area. The guide member incorporates wear-resistant materials such as natural diamond, diamond film, synthetic diamond, ceramic, carbide, sapphire, or cubic boron nitride, for enhancing its wear characteristics. |
