1. Spark erosion apparatus to cut, by spark erosion, a deformation into a workpiece (2) havinga cutting wire electrode (1);

  • an upper wire guidance head (3);

    a lower wire guidance head (4),the workpiece (2) being positioned between the upper and lower guidance heads;

    an upper support arm (5) supporting the upper guidance head and being movable, with respect to the workpiece, in an upper coordinate plane;

    a lower support arm (6) supporting the lower guidance head and being movable, with respect to the workpiece, in a lower coordinate plane independently of the upper support arm;

    and comprising, in accordance with the inventionat least one gimbal suspension (11,

         12) secured to and movably, tiltably securing at least one guidance head (3,

         4) on, and with respect to the associated support arm (5,

         6) and having orthogonal gimbal axes, said orthogonal axes intersecting at a transition point;

    means (21) secured to the at least one head and guiding the wire in a path between the outside of the at least one head remote from the workpiece and through said transition point;

    and independently controllable drive means (14,

         18) coupled to said at least one gimbal suspension and individually controlling the position of the at least one head with respect to each one of the respective orthogonal gimbal axes.
