offers the necessary filter technology to meet the specific performance requirements in microtool production. The company says its filters deliver highly filtered grinding oil in purity class NAS 7 (3-5 µm) over a long application period. In addition, they provide precise control of the coolant temperature.

Vomat filters separate dirty and clean oil in full flow, meaning that the tool manufacturer can always work with clean cooling lubricants. In addition, Vomat systems carry out backflushing as required. The degree of contamination of each individual filter element is monitored, and if a defined value is exceeded, the backflushing process is automatically initiated.

Meanwhile, the other filter elements ensure a continuous supply of clean oil. This advanced capacity control of the filter system helps to optimize energy consumption and lower operating costs for the grinding process. Precise temperature monitoring of the grinding oil with a control accuracy of ±0.2 K ensures constant optimum temperatures of the coolant media.

Steffen Strobel, sales manager at Vomat, says, “An important factor in this sensitive production environment is ultra-fine filtration of the cooling lubricants. When grinding microtools, contaminated or insufficiently filtered cooling lubricants can have a sensitive effect on the grinding result. Even minimal temperature fluctuations in the cooling lubricant pose a major threat to the final quality, as they can have a negative effect on the expansion behavior of machine components and tool substrates. Vomat’s filter technology is designed to eliminate precisely such disturbing factors and ensure optimum filtration.”
