Cutting oil purification systems remove contaminants such as metal particles, tramp oils, water, and microbial organisms to restore the oil’s effectiveness. The process begins by collecting the used cutting oil and passing it through mechanical filters that trap larger particles. Centrifugation or hydrocyclonic separation is then employed to remove finer particulates and tramp oils based on density differences. Magnetic separators extract ferrous metal particles, enhancing the purity of the oil. For water removal, vacuum dehydration techniques lower the boiling point of water, causing it to evaporate under reduced pressure. To address microbial contamination, biocides are introduced to eliminate bacteria and fungi. The purified oil may also receive additive replenishment to restore its lubricating and cooling properties before being returned to the machining process.
