What factors influence the lifespan of cutting oil?

The lifespan of cutting oil is influenced by several factors, including the type of machining operations, the materials being processed, and the maintenance practices in place. High-speed or heavy-duty machining generates more heat and wear debris, which can degrade the oil more quickly. Contamination from metal shavings, tramp oils, water, and microbial growth reduces the oil’s effectiveness. Regular maintenance, such as filtration, pH control, and microbial management, extends the oil’s usable life. Environmental factors like temperature and exposure to air can also affect the oil’s stability over time.
