The invention relates to a method for electrochemically machining blades of a turbomachine having at least one U-shaped or trapezoidal cross-sectional profile of the surface to be treated, wherein an electrode array having at least three electrodes that can be moved in different directions is provided. The electrodes are moved from a start position having a first distance to the surface to be machined into an end position having a second distance to the surface to be machined, wherein in the end position, a closed work surface of the electrodes having a negative shape of the surface contour of the surface to be machined is located opposite thereof. The invention further relates to an electrode array for carrying out an electrochemical machining, wherein the electrode array comprises at least three electrodes that can be moved in different directions to one another, and to stationary mounting, wherein the electrodes can be moved from a start position to an end position.
