Precision tool manufacturing depends on advanced grinding and coating technologies, with ultrafine coolant filtration being key to maintaining tool quality and reducing costs. Vomat's filtration systems, showcased at IMTS, ensure clean oil supply, improve energy efficiency, and extend filter life.

State-of-the-art grinding, measuring and coating technology — in order to grind precision tools with high accuracy, tool manufacturers must be technically up to date and optimally coordinate all parameters involved. Ultrafine filtration of the cooling lubricants within the overall machining system plays a key role here. This is because, on the one hand, clean coolants have a significant influence on the quality of the ground tools and, on the other hand, finely filtered grinding oils that remain in the system for a long time contribute to considerable cost savings in production. Filter manufacturer Vomat from Treuen/Germany will be showing a cross-section of high-performance filtration technology at IMTS North building, level 3, booth 237475.

Metal abrasion, dirt and decomposition products - if contaminated grinding oils were not finely filtered, they would have to be replaced at very short intervals. This becomes all the more important as development progresses: Because whether conventional, synthetic or water-miscible — the area of cooling lubricants is now a sensitive, highly technical topic in modern metalworking. Thus, the choice of the right coolant depends on the respective process factors. Thanks to special combinations of active ingredients, tool manufacturers can use coolants that are precisely tailored to their machining applications.

Steven Lowery, Executive VP from Executive VP Oelheld U.S., the official reseller of Vomat Filtration Systems in North America: “In today's tool manufacturing, efficient coolant filtration represents more than just filtering a necessary auxiliary material. And anyone who uses innovative Oelheld grinding oils in their grinding workflow can therefore make no compromises, especially when it comes to ultra-fine filtration. The decision for the right filter system when grinding hard metals (HM) and high-speed steels (HSS) or as a blending option is therefore an important prerequisite for quality and efficiency of the entire value chain. After all, contemporary ultrafine filtration technology really exploits the possibilities of advanced Oelheld MWFs.”

Modern filtration technology

Thanks to their special design features, Vomat filters are optimally capable of filtering even the latest MWF generations reliably and cost-efficiently. Thanks to special high-performance precoat filters, full-flow filtration ensures 100 percent separation of dirty and clean oil. In this way, the system permanently supplies clean oil in NAS 7 quality (3-5 µm) to the grinding system. Another advantage is the energy efficiency of the Vomat technology: Vomat systems filter and flush according to demand. This means that the backwash cycles are controlled depending on the degree of contamination of the filter elements.

Steven Lowery: “The on-demand filtration of the oil in combination with the coordinated filter cleaning brings many advantages to the tool manufacturer. It also means that less power or energy is consumed. Likewise, the service life of the individual filter elements is increased, and the cooling lubricant can remain in the system longer. In addition, Vomat systems are designed to add as little heat as possible to the media, which in turn requires less cooling power.”

Since every tool grinder has its own workflows and processes, Vomat offers a wide range of options on the standard platform of the FA machine series, for example, to optimally integrate filtration technology into the respective individual circumstances. The spectrum ranges from small stand-alone systems to large-scale industrial central systems.

Steven Lowery, Executive VP from Oelheld, the official reseller of Vomat Filtration Systems in North America: “The exacting requirements of the metal processing industry in North America regarding quality and cost-effectiveness can be met only through high-performance machine technology and precision tools. This also means customised troubleshooting, flexible services and speedy deliveries. To achieve this, we need to be close to our customers. We meet these high standards. With Vomat ultrafine filtration technology, they have a wide range of high-performance filters at their disposal, which promise productivity, optimize the quality and ultimately increase the profit.”
