  • Method and arrangement for the electrochemical machining of a workpiece
    Patent number: 6214200
    Abstract: In a method for electrochemical machining, the working distance is set by contacting the workpiece with the electrode, increasing the distance between the workpiece and the electrode by a first distance, detecting whether the contact between the electrode and the workpiece is broken, and further increasing the distance between the workpiece and the electrode by a second distance. Owing to this method, very small working distances can be set with a limited risk of short-circuiting and flash-over.
