Vomat Creating clear conditions even on a large scale
When grinding carbide and HSS tools in large industrial volumes, large filter and central systems for cleaning contaminated grinding oils are worthwhile in several ways.
The Vomat filter technology separates dirty and clean oil 100 % by full-flow filtration and, thanks to modern high-performance pre-coat filters, provides the system with grinding oil in the quality class NAS 7 (3-5 µm) over a long period of time, according to the company.
Vomat systems can be used to rinse and filter as required. The back flushing cycles are regulated depending on the degree of contamination of the filter elements. This allows Vomat to react precisely to customer-specific cutting volumes. The disposal volume is reduced to a minimum with the lowest drag-out loss. Steffen Strobel, technical sales manager at Vomat: “The long service life of the cooling lubricant with an optimum degree of cleaning leads to longer service life of the grinding wheels, lower maintenance required for the equipment and reduced machine downtimes. In addition, the efficient disposal of the backwash sludge in large filter systems reduces operating costs.”
Vomat ultra-fine filter systems are available in various sizes from 120 liter flow capacity per minute to large filter or central filter systems with 960 or 1,200 liters per minute. If the capacity requirement for filtration performance increases, for example if many grinding machines have to be controlled centrally, then the large Vomat ultra-fine filtration systems come into consideration. Steffen Strobel: "Tool manufacturers or regrinders can also use a Vomat filtration system, which can be upscaled from 1,200 liters/minute in 1,200 liter increments. The large selection of modules and additional optional features offer maximum flexibility".
One example is a large German tool manufacturer that recently doubled its production capacity. The demands for filtration technology have changed accordingly. The new Vomat FA 960 large system is optimally adapted to the production-specific conditions and can be connected to 12 grinding machines, Vomat explains. A well designed filter capacity control with back flushing only on demand reduces the energy consumption.
