Dr. Johannes Heidenhain GmbH

Geschichte

Dr. Johannes Heidenhain GmbH is a privately owned enterprise located in Traunreut, Germany that manufactures numerical controls for machine tools, as well as mechatronic measuring devices for length and angle.These linear and angle encoders are built for use in automated machines and systems, particularly in machine tools.HistoryThe company began as a metal etching factory founded in Berlin by Wilhelm Heidenhain in 1889 that manufactured templates, company plaques, product labels, and scales.In 1928 Heidenhain invented the Metallur process. This lead-sulfide copying process made it possible for the first time to make exact copies of an original grating on a metal surface for industrial use. By 1943, Heidenhain was producing linear scales with accuracy of ± 15 µm and circular scale disks with accuracy of ± 3 angular seconds.After World War II, in 1948, Dr. Johannes Heidenhain, a pupil of Otto Hahn, founded the present company in Traunreut.Its invention of the Diadur process enabled it to apply very fine structures of chromium on suitable substrates, such as glass.The Diadur process was the basis in 1952 for adding optical position measuring devices for machine tools to the product program. These were followed in 1961 by photoelectrically scanned linear and angle encoders.In 1968 Heidenhain manufactured its first digital readouts.The first Heidenhain numerical control was launched in 1976.

"HEIDENHAIN développe et produit des codeurs linéaires, codeurs angulaires, codeurs rotatifs et commandes CNC pour le positionnement exigeant. Son portefeuille de produits est complété par des palpeurs tactiles, systèmes de caméras, palpeurs de mesure, afficheurs numériques, convertisseurs de signaux, appareils de contrôle et appareils d'inspection. En outre, ses solutions logicielles pratiques pour l'atelier numérique permettent aux utilisateurs finaux de numériser entièrement leur écosystème de fabrication. Depuis plus de 130 ans, l'entreprise est un pionnière dans le domaine de la mesure, de la régulation et des systèmes d'entraînement."
