The invention relates to an ECM system comprising a holder for the arranging of at least one component to be machined and at least one machining station for the electrochemical machining of the at least one component at at least one machining position. The ECM system has a positioning apparatus, which is designed to mount, in a predefined position, a machining platform arranged on the positioning apparatus, and the machining platform comprises at least one machining station having at least one electrode arranged thereon, which electrode can be moved along a machining path in order to machine the at least one component that can be arranged on the holder.

ECM system, having a holder and a machining platform

The invention relates to a method machining a particularly planar component by means of electrochemical machining, wherein the component has internal stresses resulting particularly from preceding manufacturing steps. In a first step a) of the method, the component to be machined is provided. Subsequently, in step b), at least two tools are provided in the form of electrodes and, in step c), an electrolyte is provided between the component and the at least two electrodes. In step d), a positive voltage is applied to the component and a negative voltage is applied to the at least two electrodes. Thus, in step e), by moving the at least two electrodes along their respective movement paths with respect to the component, electrochemical machining can take place; in the process, the gap between each electrode and the component is flushed with the electrolyte at least intermittently.

Method and apparatus for machining components by means of electrochemical machining

The invention relates to a machine having a base () and at least one work station () that has a module () for electrochemically machining a workpiece (). The module comprises: a frame (); and an electrode arrangement, having at least one electrode (), which is mechanically connected to the frame, and a drive () for moving this electrode, which drive is attached to the frame; a workpiece holder () for separably attaching the workpiece; and a positioning device () for displacing the workpiece holder and the module relative to each other.
