About Gehring Technologies
Gehring Technologies GmbH + Co. KG, headquartered in Ostfildern (Baden-Württemberg), develops and manufactures machines and production solutions for the fine machining of bores as well as for conventional and electrified powertrains. Its core competence is honing technology: the modular machine series Powertrainhone, Lifehone and Deephone machine bore diameters from 0.8 mm to 2,000 mm and bore lengths up to 24,000 mm. The portfolio is complemented by laser technology (laser roughening, laser structuring, laser coating, laser welding), trickling, and diamond- and CBN-based tools and abrasives developed in cooperation with the sister company Diato GmbH. For e-mobility, Gehring supplies turnkey systems for hairpin stator production – from pin manufacturing through twisting and welding to impregnation, coating and automation. In Naumburg, Gehring Production GmbH + Co. KG operates a competence center for large-part machining, assemblies and installations. Customers come from the automotive and supplier industries as well as hydraulics and pneumatics; with locations in the USA, China, India, France and Mexico, the group supplies customers worldwide.
