In the paper the electrodischarge and electrochemical dressing method of super hard grinding wheels using segmental tool electrode and low concentration of electrolytes has been presented. Also the investigation stand for dressing has been depicted. The experimental results concerned forming of cutting surface of grinding wheels (CSGW) in two different processes: electrodischarge profiling and electrochemical dressing. The obtained results confirmed usefulness of both of these processes in forming macro- and microgeometry of CSGW, reduction of geometrical deviations and form dressing of super hard grinding wheels with metal bond. Potential application of electrochemical and electrodischarge methods using diluted solutions of electrolytes for dressing of grinding wheels has been presented. The hybrid system of electrodischarge and electrochemical grinding wheels dressing has been proposed.
