About Grenzemann Präzisionstechnik GmbH
Grenzemann Präzisionstechnik GmbH is a family-owned company founded in 1979 and based in Eisenbach in the Black Forest. The company manufactures precision parts and complete assemblies from metals, non-ferrous metals and plastics. Its value creation includes CNC turning of diameters up to 250 mm including complete machining with turn-mill centers and fully automatic lathes with loading devices, CNC milling on machining centers with up to five axes in combination with CAD-CAM software, and the assembly of complete assemblies. In addition, processes such as grinding, broaching, slotting and gear hobbing are available; surface treatments and hardening processes are carried out through partners. Customers can be found, among others, in mechanical engineering, gearbox manufacturing and electric motor manufacturing, in magnetic, medical, water and lighting technology, in pneumatics and in model making. The quality management system has been certified to DIN EN ISO 9001 since 2002.
