Coolant filtration

During the different mechanical treatments like miling, cutting, turning, grinding or honing, cooling lubricant filters (KSS filter) ensures that coolants are cleaned whilst being used. Cooling lubricant is contaminated by the smallest particles from the different mechanical processing procedures in the metal processing industry.
