About Fiedler Maschinenbau GmbH
Fiedler Maschinenbau GmbH is a medium-sized family-owned company in Lützen, Saxony-Anhalt, in existence since 1953. Its core business is the CNC machining of turned and milled parts in small, medium and large production runs; CNC turning is possible up to Ø 1200 mm and CNC milling up to 2940 x 1000 x 950 mm with a table load capacity of up to 2.5 t. The machine fleet comprises 22 CNC machining machines, including 6 large machining centers, as well as equipment for sawing, grinding, keyway broaching, slotting and balancing. The service portfolio ranges from assembly manufacturing, jig and fixture construction and the design of special applications to mounting including shrink fitting, through to testing such as pressure, burst and leak tests up to 200 bar and dye penetrant inspection. Casting and forged parts are procured in cooperation, and welding work (DB approval), heat treatment and surface treatments are performed. The company supplies, among others, Deutsche Bahn AG in the wheelset sector as well as the automotive, machinery and plant engineering industries.
