About Braun Präzisionstechnik
Braun Präzisionstechnik GmbH is a medium-sized company from Biebergemünd in Hesse with over 40 years of experience in CNC machining. The company specializes in precise turning and milling parts and manufactures components as a contract manufacturer, ranging from small millimeters to components over 3 meters in length. The manufacturing spectrum includes CNC turning from Ø1.5 mm up to Ø450 mm and up to 650 mm in length, as well as CNC milling in 3- to 5-axis processing, supplemented by CAM programming for complex geometries. All machinable materials such as steel, stainless steel, aluminum, non-ferrous metals, plastics, and special alloys are processed. Additional processes such as heat treatment, surface treatment, welded assemblies, and sheet metal parts are offered through a qualified partner network, complemented by assembly and warehousing. Customers come from mechanical engineering, plant engineering, glass industry, medical and pharmaceutical industries, electrical engineering, as well as measurement and control technology. Production is ISO 9001:2015 certified.
