About Maschinenbau Seibert
Hermann Seibert GmbH is a company that has been run as a family business for over five decades, based in Lambrecht (Rhineland-Palatinate), active in mechanical and fixture engineering. The company manufactures complex mechanical components and assemblies as well as complete special machines and systems with a high degree of in-house production depth – from design through machining to assembly and on-site commissioning. The range of services includes CNC milling and CNC turning, cylindrical and surface grinding, lapping, broaching of keyways, die sinking EDM and the dynamic balancing of rotors such as fan wheels and electric motor armatures. Service offerings include repair welding, TIG welding, brazing, flame spraying using the cold spray process (steel, non-ferrous metals, ceramics) and the restoration of bearing seats by thermal spray coating. Materials machined include structural steels, hardened tool steels, stainless steels, light and non-ferrous metals including titanium, as well as machinable and glass- or carbon-fiber-reinforced plastics. Customers come from mechanical and fixture engineering, precision engineering, electric motor manufacturing and special machine construction.
