1070 – 13 – Getting the Most Out of Your Cutting Fluid Part 1

One of the added benefits of cutting fluids is their longevity. Many types of cutting fluid can be continuously reused. As a rule, oils stand up to the wear and tear of machining better than water-soluble cutting fluids. Just be sure that the tramp-oil from the machine itself does not contaminate the cutting fluid.

Choosing the right lubricant also depends on the oil’s viscosity, which will provide lubrication. It’s also important to check the acidity of the oil; highly acid oil may mean that the cutting fluid has gone rancid.
