ABSTRACT:
Spark erosion system for removing connection elements from a structure (W,60), having a drill head (3) [(4)?], a rotational drive (10) by means of which a tool is caused to rotate, a positioning system (15) for moving the tool as well as a process control (48) for controlling the overall system, the system comprising an energy unit (30) and an electric circuit, and in that, furthermore, the tool is a tube electrode (5) through whose interior (5a) a dielectric can be guided to the surface (61a) of the connection element (61) to be detached, which surface (61a) faces the interior (7a), in order to cause a voltage between the tube electrode (5) and the connection element (61) to be detached, for implementing a spark erosion.
