A device and a method for producing a blade airfoil from a workpiece which comprises at least two gaps and at least one blank arranged between the two gaps, wherein the blank comprises two opposite lateral faces which are bounded by a base, a top and a first and a second edge. The method comprises: (a) arranging the first and second electrodes in the first and second gaps, the surface of the workpiece forming an annular space surface at the gaps, (b) applying a positive voltage to the blank and applying a negative voltage to the first and second electrodes, (c) moving the first and second electrode in the direction of the first and second lateral faces.
Step (b) is preceded by passing electrolyte between the two electrodes over the top toward the base.

The present invention provides a continuous machining system, which comprises an electrochemical machining module, a separating module, and a vibration reducing module. The electrochemical machining module performs an electrochemical machining to a material strip for forming a plurality of components on the material strip. The separating module separates the plurality of components from the material strip. Thereby, the machining time is saved, and thus achieving the purposes of continuous machining and mass production. The vibration reducing module is located between the electrochemical machining module and the separating module. The vibration reducing module can ease the vibration of the material strip. Consequently, the influence of vibration on the electrochemical machining precision of the material strip machined by the electrochemical machining module may be minimized.
