Das Projekt "Hochpraezise elektrochemische Bearbeitungstechnologie einschliesslich Wertstoffrecycling" wird vom Umweltbundesamt gefördert und von Universität Düsseldorf, Institut für Physikalische Chemie und Elektrochemie II durchgeführt. The project addresses a basic improvement of the present. Widely used ElectroChemical Machining (ECM) technology. The new technology will be developed from the present laboratory stage to a reliable. Predictable and ecological clean mass production technology for precision parts. The accuracy will be improved from the present 0.25 mm. by at least two orders of magnitude and recycling of the dissolved metals will solve the urgent waste problems as encountered with the present technology that produces 8,000 tons/year of chemical waste containing highly toxic chromium 6 and other heavy metals. The feasibility of the SPECTRUM will be shown by producing key components and the technology will be made available to the partners as well as to the European industry.
