Demanding grinding applications require powerful filtration systems that have a poitive effect on the entire production process. The Micro Filtration Specialist Vomat from the town of Treuen/Germany provides the metalworking industry with custom tailored filtration concepts ranging from small to large industrial systems. Coolants used in tooling machines using wet cutting chip removal are usually subject to heavy contamination. Hydraulic oils, slideway oils and greases are introduced into the emulsion and prevent at a high enough concentration the all important oxygen exchange.In conjunction with floating and caked on solids this mixture provides the perfect breeding ground for bacteria and fungi which quickly decompose and render the coolant unusable. In addition, chips and other contaminants from the grinding process amplify this condition. Only continuous maintenance and filtration can significantly extend the life of the coolant. "To achieve filtration in the 3-5 micron range, many plant operators with conventional filtration equipment have to cope with high costs of filter media such as cellulose or paper," says Stephan Hecht, Vomat's general agent in Elgin, Illinois. "In addition, downtime and production line shutdowns can cost manufacturers of close tolerance products up to 25 percent of their total production costs. However, this is not a necessary evil, since Vomat offers a way out of this dilemma with their proven FA series filtration systems."
