About us
Maschinenbau Bühring Betriebsunternehmen GmbH is a fourth-generation medium-sized family business in Dreileben (Wanzleben-Börde) that operates as a manufacturing company in mechanical and metal engineering. The service portfolio includes laser cutting and sheet metal processing on Trumpf systems (machining area 4,000 x 2,000 mm, structural steel up to 25 mm, stainless steel up to 20 mm, aluminium up to 15 mm), tube laser cutting up to Ø 240 mm, CNC milling in three- to five-axis versions, CNC turning, two-sided tube end machining, bending on hydraulic CNC press brakes as well as MAG welding with approx. 30 manual welding stations and five welding robots from IGM. The core processes are complemented by an in-house fixture and jig construction department including 3D design, a steel brushing machine for oxide layer removal, metrology with a 6-axis measuring arm, and its own assembly lines for customers such as Krone, Müthing and Agco. External services such as painting, powder coating, galvanizing and hardening are handled via specialized partners. The main customers are the agricultural machinery sector (largest share of the order portfolio) as well as crane construction, metal construction, mechanical engineering and construction machinery.
