摘要： The invention relates to a method for machining a workpiece by an electrochemical machining process in which material is removed from the workpiece in an electrolyte liquid, where the electrolyte liquid is then filtered in a membrane filter system which has a membrane that undergoes a relative movement in the membrane filter system during the filtering process, and the filtered electrolyte liquid is reused for the electrochemical machining process.

摘要： A method of forming a curved-shaped processing hole in a workpiece by electromechanical machining includes a step of feeding an electrolytic solution through an inner channel of a processing electrode and jetting the electrolytic solution from an outlet opening of the inner channel disposed on a tip surface of the processing electrode, a step of applying a potential difference between the processing electrode and the workpiece while jetting the electrolytic solution from the outlet opening of the processing electrode, and a step of forming the curved-shaped processing hole in the workpiece. In the jetting step, at least one of a current density distribution on the tip surface of the processing electrode or a flow velocity distribution of the electrolytic solution jetted from the outlet opening is eccentric to a downstream side of a curving direction of the processing hole with respect to an axial center of the tip surface.

摘要： An electrochemical machining apparatus for forming turbine blades includes a main base, an upper seat and an electrode unit. The main base includes a working platform for allowing a turbine blade to be placed thereon. The working platform includes an upper step stage for resisting the turbine blade, and a lower step stage for keeping a predetermined working space from a portion of the turbine blade desired to be cut. The main base has a guiding channel for allowing an electrolyte to flow through the predetermined working space. The upper seat is configured to cover above the main base and to contact one side of the turbine blade to form an electrical connection. The electrode unit includes an anode electrode electrically connected to the upper seat and at least one cathode electrode disposed on the main base.

摘要： A method for removing material from a component that is connected as an anode is disclosed. In an embodiment, an electrode that is connected as a cathode is guided to the component such that a gap is formed, an electrolyte is introduced into the gap, and a closed system is formed for the electrolyte by the formation of a duct. The electrolyte is continuously guided from an inlet opening to an outlet opening of the duct. Forming the duct, e.g., by guide elements that are mounted on the electrode, ensures that only those surface parts of the component to be machined from which material is to be removed enter in contact with the electrolyte while the other surface parts do not enter in contact with the electrolyte. Since the electrolyte is continuously guided across the surface, used electrolyte is continuously discharged along with residual matter while fresh electrolyte is delivered.

摘要： A method for processing a constructed, liquid-cooled piston of an internal combustion engine, the piston including an upper piston part and a lower piston part, which are supported by a joining plane and are connected to each other in a bonded manner. An electrochemical method, such as electrochemical machining, is used to produce a passage opening or a hole in the piston. By means of the method, material is selectively removed after the completion of the upper part piston, the lower piston part, or the piston after the two piston parts have been joined. The electrochemical machining allows an arbitrarily geometrically designed topography having at least one passage opening, a hollow, or an oil pocket in cooling areas or non-cooling areas to be created on the piston.
