Abstract

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.
