About us
Kaiser Präzision GmbH is a family-owned company based in Keltern (75210, Baden-Württemberg) that has been active in grinding technology and the manufacture of precision parts and tools for more than 35 years. Its range of services includes centerless grinding (plunge and through-feed grinding), cylindrical external and internal grinding, surface grinding and profile grinding with surface roughnesses down to Ra 0.02 and tolerances down to 0.002 mm. This is complemented by EDM (sinker EDM including thread EDM), turning and milling, heat treatment such as induction hardening, plasma nitriding, annealing and vacuum processes, as well as coatings such as PVD, chromium nitride, TiN, TixCo3 and DLC; laser marking with a fiber laser rounds off the spectrum. Materials machined include steel, stainless steel, carbide, ceramics, copper, Ferrotitanit, titanium and Albromet. Production ranges from one-off custom manufacture to drawing through to larger series. Customers come mainly from the automotive industry, mechanical engineering and food technology.
