In swinging wire guides for generally conical finishing surfaces, the problem exists of a reliable automatic coaxial setting of the guide axes according to the particular angular position of the wire electrode in the workpiece finishing zone. As a solution, the wire guides (DF1, DF2) supported swinging on the support elements (TO1, TO2) are joined together by a coupling device, which has a guide member (FG) joined correspondingly with the support elements. The latter is set by the relative movement of the wire guides (DF1, DF2) to the desired angular position of the wire guides according to the ideal wire guide axis (D-D). Through swinging coupling gears (SK1, SK2) the angle position of the guide member (FG) is transmitted to the wire guides (DF1, DF2). These coupling gears suitably contain a jointed parallelogram (LK) and a rotary coupling member (DK) for the transmission of two swinging movement components, perpendicular to each other, in the sense of a total biaxial forced coupling of the guide member with the wire guides. |
