Why is pH control important in cutting oil maintenance?

Maintaining the correct pH in cutting oil is essential because it affects the fluid’s stability, effectiveness, and compatibility with machine components. An optimal pH range prevents corrosion of metal surfaces and inhibits microbial growth. If the pH becomes too low (acidic), it can lead to increased corrosion and encourage bacterial proliferation. If it is too high (alkaline), it may cause skin irritation for workers and reduce the oil’s lubricating properties. Regular monitoring and adjustment of the pH ensure that the cutting oil performs effectively and safely over time.
