About us
Edmund Becker GmbH of Dortmund is a family-owned mechanical engineering and grinding technology company specialising in the manufacture and maintenance of machines and equipment for energy and steelworks technology. The service portfolio comprises cylindrical, crowned and concave grinding up to Ø 2,300 x 6,000 mm or Ø 1,500 x 9,000 mm and 40 t unit weight, the grinding of current-carrying rolls, backup rolls and circular knives, as well as the manufacture and repair of spare and reserve parts. In addition, the company offers machining on lead and thread turning lathes, vertical turret lathes and a 5-axis table-type boring machine, as well as electrical machine winding with vacuum impregnation. Virtually all materials are machined, including PU-coated, rubber-covered, steel, cast and austenitic rolls and rollers. Customers come mainly from the rolled steel industry, strip galvanizing, mechanical engineering, energy plant technology and shipbuilding. The company was founded in 1981 and emerged from the business Maschinenbau Edmund Becker founded in 1974.
