About Winterhoff Maschinenbau
Winterhoff Maschinenbau GmbH & Co. KG is a medium-sized family business from Zernien-Gülden in the district of Lüchow-Dannenberg (Lower Saxony), founded in 1991 by Burkhard Winterhoff. The core business is contract CNC machining with a focus on the processing of large workpieces: milling is performed on parts up to 22 m in length (drilling and milling machine Zayer KCU 22.000), turning is performed up to 2 m in length and 450 mm in diameter. The service portfolio also includes steel construction and welded fabrications (MAG/TIG per DIN EN 1090 and DIN EN ISO 3834-2), cutting by plasma cutting, surface finishing such as sandblasting, painting and galvanic treatments, CAD/CAM programming (Solidworks, Mastercam, Heidenhain) as well as assembly. Customers come from the automotive, railway and aviation industries, medical technology, mechanical engineering, amusement park technology, defence and petroleum industries. On a site of around 34.000 m² with approximately 6.500 m² of production space, about 50 employees manufacture everything from individual parts to series production. The quality management system has been certified to ISO 9001 since 2014.
