ABSTRACT:
The invention relates to a method for manufacturing a tool electrode for the electrochemical machining of workpieces, particularly for components for fluid bearings with the following processing steps: (a) Providing an electrode body made of a conductive base material which has an essentially smooth surface; (b) Coating the surface of the electrode body with an insulating material; (c) Removing the insulating material from locations on the surface of the electrode body that correspond to a pattern which is to be formed on the surface of the piece by means of electromechanical machining.
