About Albrecht Sondermaschinen
Albrecht Sondermaschinen GmbH in Nordhausen implements industry- and customer-specific solutions in special-purpose machine building – from design through manufacturing to assembly and maintenance. The range of services includes leak testing systems (underwater testing, differential pressure, flow, vacuum and tracer gas methods with helium or hydrogen), marking and signing systems (needle embossing, scribe marking, electrolytic, laser marking, barcode, DataMatrix, vision), assembly fixtures as well as handling and automation with robots and PLC controls. In-house manufacturing capacity includes 5-axis machining up to X=1250 mm, CNC milling, CNC turning as well as conventional drilling, turning and grinding; additionally, heat treatments such as cold nitriding (blackening) and hardening are offered. Customers come from the automotive industry (passenger car connecting rods, axle carriers), the electric motor industry and agricultural machinery. The services are based on around 20 years of experience in special-purpose machine building; the service portfolio includes machine servicing, maintenance, retrofit solutions and CNC programming.
