Use case with GMN Paul Müller Industrie GmbH & Co. KG:
Edge services for motor spindles

Digital spindle technology from GMN: the future of networked manufacturing

GMN Paul Müller Industrie GmbH & Co. KG demonstrates how modern spindle technology and edge computing are transforming the machine tool industry with the use case ‘Edge services for motor spindles’. IIoT-enabled GMN spindles are used in a Danobat-Overbeck grinding machine to record and analyse machine data such as vibrations, temperature and speed in real time via the IDEA-4S embedded system.

Potential of machine data analysis

The system processes data directly at the spindle and transmits it securely to an IIoT platform via an IO-Link interface - Data Act-compliant and without direct access to the company network. This opens up new possibilities for process optimisation, predictive maintenance and reducing downtimes. IDEA-4S reacts to critical conditions within milliseconds, such as excessive vibrations, thereby increasing the quality and reliability of production.

The digital twin: a new dimension in machine monitoring

A central element is the digital twin: it visualises the machine as a 3D model in an interactive dashboard, including configuration, running times, service history and environmental indicators such as CO₂ footprint. Changes to the hardware are automatically updated in the model.

The use case is part of the ESCOM research project, which is developing a European infrastructure for secure data exchange in accordance with Gaia-X standards. Companies benefit from automated analyses, increased efficiency and the ability to share their data confidently in the data ecosystem.
