Efficient Grinding with Data-based Cooling Lubricant Monitoring

Data-based monitoring of cooling lubricant Ensuring the right chemistry during grinding

2026-02-17 From Daniel Schauber* 7 min Reading Time

Data-based cooling lubricant monitoring makes grinding more stable and efficient: sensor data on emulsion health, grinding forces and spindle power enables requirement-based fluid supply, supports digital twins and can cut energy use by up to 27 percent. At Grindinghub 2026 in Stuttgart, visitors will learn how Umati and OPC UA connectivity helps integrate these data streams for higher surface quality and fewer rejects.

In the grinding process, tiny imperfections make the difference between a good part and a reject. To achieve a perfect grind, not only do the mechanical components at the factory have to be set up correctly - the chemistry has to be just right as well. This brings an often underestimated component into focus: The cooling lubricant. Data-based cooling lubricant monitoring is an essential part of achieving autonomous production and optimal grinding results. This monitoring forms the link between the chemistry and the mechanical components and makes the grinding process more robust, more efficient and more sustainable thanks to standardized data exchange and the use of digital twins.

This is also where the Umati (Universal Machine Technology Interface) connectivity initiative comes into play, ensuring smooth data transfer in the factory. As a global mechanical engineering community based on the OPC UA communication standard, Umati enables machines to communicate with each other regardless of the manufacturer. This creates the necessary interoperability to seamlessly integrate data from cooling lubricant monitoring into higher-level IT systems or cloud platforms, paving the way for plug-and-play connectivity in the industrial ecosystem. At the Grindinghub trade fair, organized by the VDW (German Machine Tool Builders' Association) in Stuttgart from May 5 to 8, 2026, visitors will learn more about optimized cooling lubricant supply for achieving the highest surface qualities.
