In modern metalworking, the quality of the coolant lubricant (KSS) not only determines the tool life but also influences the entire value chain. Full-flow fine filtration, intelligent control, and temperature-optimized processes make KSS management a central lever for efficiency, product quality, and sustainability. The filter specialist Vomat from Treuen demonstrates with its modular fine filter systems how filter technology today not only 'cleans' but actively contributes to the optimization of the entire production.
Still, KSS management is often viewed merely as a necessary peripheral in many companies. However, the purity of the coolant lubricant directly and measurably influences key figures such as scrap rate, machine availability, tool costs, and energy consumption. A modern, integrated KSS management therefore includes continuous fine filtration in full flow, temperature-stable cooling, demand-oriented operation of pumps and filter elements, as well as well-thought-out concepts for material disposal and recycling.
Especially in tool grinding, these components work together: The cleaner the grinding oil and the more stable the temperature, the better geometry, surface quality, and tool life can be reproduced. At the same time, KSS remains in the system significantly longer, reducing costs for new setups, storage, and disposal.
How Vomat systems optimize the entire process chain
Steffen Strobel, Technical Sales Manager at Vomat: 'Vomat consciously positions itself not only as a filter supplier but as a solution provider for the entire KSS peripheral in metalworking. We deliver everything from individual units to large industrial central systems. And all offer the same advantages:'
Full-flow fine filtration with constant purity
Vomat fine filter systems separate dirty and clean oil in a full-flow process 100 percent and achieve cleanliness classes of NAS 7 (3 to 5 µm). This ensures that the grinding process has extremely clean KSS available at all times – a crucial factor for dimensional accuracy, surface quality, and tool life.
Demand-oriented backflushing and energy efficiency
The degree of contamination of each filter element is monitored; backflushing cycles only occur when they are actually necessary. While one element is backflushed, the others continue to provide a continuous supply of clean oil. This extends the lifespan of the filter elements, reduces energy consumption, and prevents process interruptions.
Temperature-stable processes for µ-precise quality
In addition to filtration, Vomat offers integrated cooling concepts that keep the KSS within a narrow tolerance range (up to approx. ±0.2 to 0.5 K, depending on the design). This minimizes thermal influences on the tool and workpiece – a must for demanding grinding processes with tight tolerances.
Modular systems for every company size
From FA individual units to ZFA central systems with capacities in the four- to five-digit liter range per minute: The modular concepts can be precisely tailored to machining volume, machine configuration, and future expansions. This transforms filtration from an isolated unit into strategic infrastructure: KSS fine filtration, cooling, and material preparation are planned as a continuous system and directly contribute to OEE, TCO, and process reliability.
Clean processes, better parts: Quality gains through fine filtration
Clean processes mean better parts, as fine filtration directly contributes to product quality. Contaminants in the coolant lubricant act like an invisible abrasive in the production cycle: They cause scratches, rough cutting edges, thermal damage, and increased wear on grinding wheels and machine parts. With constantly clean KSS, several quality advantages arise: Dimensional accuracy and surface quality increase due to stable removal rates and homogeneous heat dissipation. Tool life is extended due to reduced abrasive wear – scrap and rework are significantly reduced due to reproducible grinding conditions. At the same time, machine downtime decreases because components such as spindles, seals, and valves are subjected to less stress. Clean machining processes thus directly contribute to delivery quality, punctuality, and competitiveness – both in series production and precision tool manufacturing.
Fine filtration is core technology, not an accessory
Fine filtration of coolant lubricants is not a 'filter box next to the machine.' As an integral part of a well-thought-out KSS management system, it influences product quality, productivity, energy consumption, and sustainability of the entire manufacturing process.
Steffen Strobel: 'Vomat systems show what modern filter technology can look like in practice: Full-flow fine filtration at 3 to 5 µm, demand-oriented backflushing, precise temperature control, and modular system architecture turn the KSS peripheral into a performance factor for the entire production chain. For grinding companies and tool manufacturers, this means: Those who think strategically about fine filtration create the foundation for stable high-performance processes and secure a decisive advantage in a demanding market environment.'
