摘要： The invention relates to a method for the production of aero-dynamic structures during the production of integrally bladed gas turbine rotors. Aerodynamic structures of an integrally bladed gas turbine rotor are produced on a rotor disk base body, whereon the end contours are precise, by removing material according to an electrochemical removal process, i.e. by means of an electrochemical machining (ECM)-process. The method comprises the following steps: a) preparing a rotor disk base body which is made of a material which is difficult to machine; b) removing the material which is between the blade wings until a specific dimension is obtained, according to a removal process; c) preparing at least one working electrode in order to finish at least one aerodynamic structure of an integrally bladed gas turbine rotor. The contours of the or each of the working electrodes are adapted to the contours of the aerodynamic structure, which are produced by means of the respective working electrode, such that a gap between the rotor disk base body and a working electrode are produced in an approximately identical manner during the removal process of the material; d) electrochemically machining the or each aerodynamic structure in an electrochemical sinking by placing the rotor disk base body and the or each working electrode in an electrolyte and by applying voltage and/or current, whereby the applied current and/or voltage is temporally pulsed; e) pressure-rinsing the gap which is filled with electrolytes between the aero-dynamic structure and the or each working electrode by a pulsed movement of the or each working electrode.

摘要： A method for manufacturing gear wheels, specifically transmission gear wheels, is disclosed. An embodiment of the method includes the following steps: a) preparation of a base body for a gear wheel, b) electrochemical processing of the base body by a precise electrochemical machining process (PECM process), where several recesses running between the teeth of the gear wheel are made simultaneously electrochemically to manufacture the teeth of the gear wheel.

摘要： Disclosed is a method for removing material from a component (10, 10') that is connected as an anode. In said method, an electrode (12) that is connected as a cathode is guided to the component such that a gap (16) is formed, an electrolyte is introduced into the gap, and a closed system is formed for the electrolyte by forming a duct. The electrolyte is continuously conducted from an inlet to an outlet of the duct. Forming the duct, e.g. by means of conducting elements (18) that are mounted on the electrode (12), ensures that only those surface parts of the component (10) to be machined from which material is to be removed enter in contact with the electrode while the other surface parts do not enter in contact with the electrolyte. Since the electrolyte is continuously conducted across said surface, used electrolyte is continuously discharged along with residual matter while fresh electrolyte is delivered such that the method can be carried out in a particularly trouble-free and expedient manner.
