World Market Leader in the Freight and Transit Railway Sectors

By utilizing joint competencies in the field of railway technology, the NSH Group is the market leader in the development, manufacture, and supply of vertical and horizontal turning machines and systems for all aspects of wheel set machining. Based on our product range, we are the only company worldwide able to completely realize automated turnkey railway workshops and mobile systems for wheelset production and repair.

For more Speed and longer Life

Imagine covering 30.5 kilometers in 8 minutes. Impossible? Not quite! Because on the high-speed line from Shanghai airport to downtown Shanghai, you cover precisely this distance at 430 km/h. The corresponding high-speed railway wheels are produced on our Kraussel lathes, and reprofiled and maintained with technologies from the NILES-SIMMONS-HEGENSCHEIDT Group (NSH). We thus provide maximum safety at top speed. This also applies to local, long-distance, and freight transport. By utilizing joint competencies in the field of rail vehicle technology, the NSH Group is the world market leader in the development, manufacture, and supply of vertical and horizontal turning centers as well as grinding machines and fully automated systems for the machining of wheel sets. Based on our product range, we are the only company worldwide able to realize fully automated turnkey facilities, automated workshops, and mobile systems for wheel set machining and repair as a general contractor.

Our leading trade fairs in September

After a long break, our two leading trade fairs are taking place again this year: AMB in Stuttgart and InnoTrans in Berlin. Together with our subsidiary, we will present our portfolio and numerous highlights from (special) mechanical engineering. We are looking forward to your visit.


Reprofiling: Underfloor machining of wheelsets by NSH subsidiary HEGENSCHEIDT-MFD

We were guests at the Karlsruher Verkehrsbetriebe. As a customer of our subsidiary HEGENSCHEIDT-MFD, they use the U200-400 underfloor machine for wheelset machining. The modern underfloor wheelset lathe not only meets all currently known work and accuracy requirements, but its overall design is also geared to future developments.
