At Grinding Hub 2026 in Stuttgart, filtration specialist Vomat from Treuen will present high-performance solutions for ultra-fine filtration and the intelligent management of cooling lubricants (CL) in Hall 7, Booth 7D80.

Ultra-fine particles from grinding abrasion, binder residues, or carbide dust can act like grinding paste during the process. They degrade surfaces, increase tool wear, and destabilize production. Consequently, effective filtration of coolants is becoming increasingly important.

At Grinding Hub, Vomat is presenting solutions for high-performance ultra-fine filtration of coolant, specifically designed for demanding metalworking applications such as tool grinding: The systems operate using controlled full-flow filtration with a backflush process, in which contaminated and clean oil are completely separated from one another. Special high-performance pre-coating filters ensure that oil meeting NAS 7 purity class (3–5 µm) is continuously available for the grinding process. “In modern metalworking, high-performance coolant filtration is more than just filtering an auxiliary material,” explains Steffen Strobel, Technical Sales Manager at Vomat. “Only through the use of state-of-the-art ultra-fine filtration technologies can the full potential of modern coolants be realized. This delivers measurable benefits in terms of quality, efficiency, and cost-effectiveness.”

Energy-efficient filtration and precise temperature control

In addition to filtration performance, the energy efficiency of the systems is also a key focus. Vomat systems operate using a demand-based filtration and backflushing strategy: The contamination level of each individual filter element is continuously monitored, ensuring that backflushing cycles are triggered only when they are actually necessary.

While one filter element is being cleaned, the other elements continue to supply the grinding process with clean oil. The result is a continuous supply of clean oil combined with an optimized energy balance.

Another key factor for stable grinding processes is the temperature of the coolant. Vomat systems enable highly precise temperature control within a range of ±0.2 K, which is crucial for reproducible results, particularly when working with high-precision tools.

Thanks to their modular design, the systems can be flexibly adapted to different production requirements. This ranges from compact solutions for individual machines to complex central systems for large-scale industrial applications.

Goty Sponsor: Committed to the future of the grinding industry

In addition to technological innovations, Vomat is also setting the stage for the industry’s future at Grinding Hub: The filter specialist is sponsoring the Grinder of the Year (Goty) 2026 competition for young talent.

The competition is specifically aimed at young professionals and apprentices in the field of grinding technology in the DACH region. The goal is to raise awareness of the complex nature of the tool grinding profession and to inspire young talent early on to embrace modern manufacturing technologies. “For Vomat, this commitment is a logical extension of our own process philosophy. The challenge impressively demonstrates that top quality in tool grinding is always the result of a perfectly coordinated overall system. Through our commitment, we aim to foster enthusiasm for technology, an understanding of processes, and a focus on quality among young professionals.”

The Goty will take place on May 6 and 7 at the competition booth of organizer KSKOMM in Hall 9, Booth 9B50.
