What processes are involved in cutting oil filtering and why is it necessary?

Cutting oil filtering involves mechanical filtration to remove solid particles, separation techniques like centrifugation to eliminate tramp oils and fine particulates, and sometimes chemical treatments to break down emulsions. Magnetic filtration targets ferrous metal contaminants. These processes are necessary to maintain the cutting oil’s lubricating and cooling properties, which are essential for efficient machining operations. Filtering extends the oil’s usable life, reduces tool wear, improves surface finishes, and minimizes health hazards and environmental impact by reducing waste and contaminant exposure.
