Abstract
A spark erosion machine having two spaced apart wire electrode guidance heads, which are forcibly coupled with one another in such a way that the guidance heads are always coaxial to one another. The forced coupling takes place by a hydraulic system that includes adjusting cylinders for the guidance heads and associated control cylinders. The piston rods of the adjusting cylinders are coupled to one another. By the use of hydraulic circuits, a displacement of the piston rods of the control cylinders leads to a corresponding displacement of the piston rods of the associated adjusting cylinders, so that the orientation of both wire guidance heads is always the same. As a result of this hydraulic system, there is no need to couple the upper and lower wire guidance heads by a mechanical linkage, so that the working zone between the heads and the lateral area for the workpiece connected thereto can be of a random magnitude.
