Axially unsymmetrical articles are electropolished zonewise, or the inside and outside surfaces of articles are electropolished zonewise and simultaneously. To this end a cathode of which the geometrical configuration and surface area correspond to the surface to be electropolished is arranged opposite an anode; more particularly, the cathode is subdivided into a plurality of segments which are non-conductive with respect to one another, through which segments a current of the necessary density is alternately passed and discontinued, at intervals, for a period compatible with the production of the desired electropolishing effect. |
