The NSH Group is the market leader in wheelset machining for rail vehicles. Special solutions of our WOTAN® grinding machines are used for this purpose. NSH Group is the only provider to offer workshop and mobile turnkey solutions for their manufacture and repair.
For decades, our machines have met the exceptionally high requirements for the production of aerospace parts, including complete machining in one clamping. WOTAN® universal grinding machines allow grinding of particularly heavy components and especially deep bores with micrometer precision.
WOTAN® grinding machines combine high efficiency and maximum precision. Individually configured to your requirements, they combine uncompromising quality 'Made in Germany' with an attractive cost structure. They are made even more effective by their ability to integrate seamlessly with existing control systems and automation.
WOTAN® machines for internal cylindrical grinding, external cylindrical grinding and universal grinding are so precise that machine components with maximum concentricity requirements such as spindles for machine tools are manufactured on them, made possible by various clamping systems, machining in one clamping and integrated measuring systems.
Each machine is designed and manufactured exactly for your specific application!
Our machines are designed and manufactured by our experienced team at our headquarters in Glauchau.
