1070 – 09 – Water Based Cutting Fluids Part 2
Chemical fluids fulfill a variety of purposes: They have nitrates that prevent rust, phosphates that soften water, defoamers to reduce foaming, soaps that offer lubrication, pressure additives that also assist with lubrication, and biocides that stop bacteria growth. Chemical fluids do an excellent job of cooling cutting surfaces.
One major benefit of using chemical fluids is their resistance to dissolving tramp oil, which makes it easy to skim the tramp oil off.
