EDM from prototype to series production
LÜNTECH GmbH in Werther (Westphalia) is a specialized contract manufacturer for EDM (electrical discharge machining) and laser processing. The company produces complex contours and precision parts using wire EDM, die-sinking EDM, start-hole and drilling EDM, and rotationally symmetric EDM. The service portfolio is complemented by HSC milling, the design of graphite electrodes via Tebis, highly precise 3D laser engraving and deep engraving, laser welding and laser deposition welding, as well as 3D laser scanning and 3D measurement methods. A key focus is the contactless, material-sparing machining of special alloys such as Inconel, Hastelloy, René and Nicrofer within the tightest tolerances. Lüntech produces pre-series, prototypes and series production and can reproduce stored geometry data at any time. Customers come from the automotive, medical technology, pharmaceutical, food, tooling and mechanical engineering sectors as well as the aerospace industry.
