A device for the electrochemical processing of a metal workpiece, including a plurality of electrodes that by way of respective linear drive units are movable in a linear manner relative to the workpiece from an initial position to a terminal position, the electrodes having a reproduction face that is directed toward the workpiece, wherein at least three electrodes are provided, the electrodes being disposed so as to be offset around the circumference of the workpiece and by way of the reproduction faces of the electrodes during the entire readjustment movement from the initial position to the terminal position engaging across one another in portions so as to be in contact, and by way of the reproduction faces of the electrodes delimiting a fluid duct that in a closed manner encircles the circumference of the workpiece.

Device for the electrochemical processing of a metal workpiece

ECM machine for electrochemically machining metallic workpieces by anodic dissolution of the workpiece by means of an electrolyte and an applied dc voltage, comprising at least one revolving table for mounting the workpiece or a workpiece carrier, as well as a portal with a transverse girder, at which one or two cathodes are provided, the at least one revolving table being rotatable about a vertical axis and being movable along horizontal guides linearly with respect to the revolving table. The transverse girder is movable vertically at vertical guides of the portal, transverse girder being rotatable about a horizontal axis of rotation. The cathode or cathodes are clampable each at one or at a common clamping device at the transverse girder and/or movable linearly along the transverse girder at least at one horizontal guide.
