Abstract: The invention relates to a method and a device for the electroerosive dressing of grinding wheels having an electrically conductive bond. The dressing tool comprises a cylindrical electrode pair divided into two, the electrodes (2, 3) of which have a different polarity and are separated from one another by insulation (4). A voltage circuit is directed via the two electrodes (2, 3). The voltage may either be a direct-current voltage of an alternating-current voltage. The dressing tool rotates and is pressed against the grinding wheel (1) with a constant force. The two dressing electrodes (2, 3) are supplied with current from a generator (7) via brushes (5,6) in such a way that it flows through the electrode (3) into the grinding wheel (1and from the latter back into the other electrode (2).
