Microbial activity in cutting oil, primarily from bacteria and fungi, can lead to degradation of the oil’s lubricating properties, unpleasant odors, and potential health hazards. Microorganisms consume additives and can produce acidic byproducts that lower the pH, promoting corrosion of machinery and workpieces. To control bacteria, maintaining proper fluid concentration and pH levels is crucial. Regular system cleaning removes biofilms and sludge where microbes thrive. Introducing biocides into the cutting oil inhibits microbial growth. Ensuring that makeup water is treated to remove microbial contaminants further reduces the risk of bacterial proliferation.
