1070 – 06 – Oil Based Cutting Fluids Part 1

Oil-based fluids contain no water and are based on mineral oils. They can be divided into two distinct types: inactive straight oils and active straight oils. We’ll go over both varieties so you can determine which type will work best for your job.

Active straight cutting oil is “sulfochlorinated”. Its chemical ingredients, which include sulfur and chlorine, make it ideal for jobs that require lubrication. Active oils can be sulfurized or sulfochlorinated Remember, though, that active straight cutting oil should not be used with brass, copper, or any of their alloys.
