March 2014 - Demanding grinding applications require a powerful filtration system, that positively supports and affects the production process. The filtration specialist Vomat provides the metalworking industry with individually tailored filtration concepts, as well as custom solutions for special applications. One example is a filtration system, which can handle Carbide and HSS waste running on the same machine, which is distributed in the U.S. by Oelheld U.S. Inc.

Filtering of cooling lubricants is an important part in grinding carbide and machining high-speed steels (HSS). Stephan Hecht of Vomat's U.S. exclusive distributor states: "Very often tool manufacturers produce tools, such as a drill made from carbide and HSS on one single machine. The generated waste, especially the HSS swarf clogs up filter cartridges and overtaxes a lot of filtration systems out on the market. Therefore, an efficient pre-filtration is essential in order to achieve continuous micro-filtration."

To solve this problem Vomat developed a special pre-filter. Due to Vomat's modular machine design, it can easily be retrofitted to any Vomat filtration system. After removal of coarse HSS material, the fine filtration of the lubricant starts in the second stage, whereby HSS swarf of 3-5 microns in size is removed.

Stephan Hecht: "With this approach the processor of mixed media on one machine is on the safe side. He will always have clean oil to at least NAS 7 available."

Vomat's design uses full stream filtration which always guarantees 100 percent separation of clean and dirty oil. Vomat's filtration systems clean and backwash their filter cartridges only on demand. Back-flushing is automatically initiated in response to the degree of contamination of each individual filter cartridge. The lesser contaminated filter cartridges will remain in service and ensure a continuous supply of clean oil.

The on demand back-flush technology pioneered by Vomat on their mixed media filtration systems, provides also for great energy savings. The the use of newly designed settling filters does not require the use of any other filtration agents and prevents the Carbide sludge and HSS swarfs to be contaminated. The residual moisture content of the chips is below five percent. Besides the manual bag disposal Vomat offers the "Sedimentator" tank with fully automatic sludge disposal into drums, which are ready for pick-up by your preferred recycling company.
