A machine for the electrochemical marking treatment of metallic surfaces, includes an electrode placed in sliding movement on the metallic surface to be treated, a buffer impregnated with etching solution for the specific metal in treatment, and an electric current circuit, suitable for electro-marking treatment of said metal, with a conductor connected to the electrode and the other conductor connected to the metallic surface in treatment; and presents to treat large metallic surfaces on plates, metal canvas or on metallic sheet in coil. The plate, canvas or the metallic sheet is placed in a electro-marking mechanism in a reciprocally movable way with respect to the electrode, in such a way to allow the electrode the electrochemical marking action on the surface to be treated even if the electrode is of limited size with respect to said surface, the electrode being movable in the and/or with the electro-marking mechanism, the buffer being impregnated with the etching solution at regular intervals, and the relative motion of the electrode on the surface being the combination of two longitudinal and transverse relative motions. |
