Abstract:
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.

Abstract:
The invention relates to an electrode for electrochemically fineboring workpieces, comprising an (electrode) tube (6) through which an electrolyte (4) is guided to a workpiece (5) to be treated; and an electrical conductor, which is connected to the electrolyte (4). Said tube (6) consists of a metal with an essentially amorphous structure, is electroconductive and is provided with an non-conductive insulating layer (10) on its outer surface, at least in sections, in order to bore boreholes with as small a diameter as possible.
Abstract:
The invention relates to an economical method for treating work pieces, using an electrochemical treatment device which has at least one electrode, preferably a cathode (12), at least one liquid outlet (13), which is situated close to the electrode (12), at least one supply line (14), which opens into said liquid outlet (s) (13) and by which means the electrolyte is supplied, and an at least one discharge line (15) through which the electrolyte can be removed. The inventive method provides that the work piece (8) is re-treated in the same treatment device or one or more essentially identical treatment devices before or after the electrochemical treatment.

Abstract:
Изобретение относится к очистке электролита и может быть использовано для подачи, регенерации электролита при электрохимической обработке. В способе осуществляют нейтрализацию токсичных соединений хрома в электролите, при этом в первой фазе процесса водородный показатель электролита понижают до значения pH 1 соответствующего кислой среде. Во второй фазе поддерживают значение водородного показателя электролита равным pH 1 и производят впрыск дозы реагента, нейтрализующего токсичное соединение хрома, контролируют изменение окислительно-восстановительного потенциала, и если его значение увеличивается, то производят очередной впрыск реагента. Процесс повторяют до тех пор, пока окислительно- восстановительный потенциал будет оставаться неизменным или будет уменьшаться в течение достаточно длительного времени. В третьей фазе значения водородного показателя электролита увеличивают до заданного уровня рН 2 . Изобретение обеспечивает экологически чистую технологию электрохимической обработки, повышает качество очистки электролита, позволяет автоматически удалить токсичные ионы из отработанного раствора и обезвредить шестивалентный хром в растворе электролита без предварительного отделения шлама.
Abstract:
Electrochemical machining method and apparatus wherein in one aspect of the invention, the machining voltage is selected to maintain the highest current without initiating substantial hydrolysis of the electrolyte flushed between the work piece anode and tool cathode. In another aspect of the invention, the Low Machining Potential Voltage (LPMV) and High Machining Potential Voltage (HMPV) for a particular work piece material are identified and the work piece is machined using a voltage at or between the LMPV and HMPV. In yet another aspect of the invention, direct perturbation of the Beta Insulating Layer (BIL) is carried out in an optimally small (between about near zero to about 10µ) inter-electrode gap (IEG) with constant and simultaneous pulling in and pushing out of the electrolyte through the IEG.
