Effective cutting oil purification employs a combination of techniques to address various contaminants. Mechanical filtration removes solid particles using filters of different micron ratings. Centrifugation separates tramp oils and fine particulates based on density differences. Magnetic filtration targets ferrous metal particles, enhancing overall contaminant removal. Ultrafiltration and nanofiltration use semi-permeable membranes to eliminate emulsified oils and microscopic contaminants. Vacuum dehydration removes water and dissolved gases by lowering the boiling point under vacuum conditions. Chemical treatments, such as coagulants and biocides, help in breaking down emulsions and controlling microbial growth. Integrating these techniques ensures comprehensive purification and extends the fluid’s effective life.
