1070 – 10 – Oil Based Cutting Fluids Part 3

Semi-chemical fluids have different levels of soluble oils and chemicals. These mixtures are fine-tuned to the type of metals the fluid will be used to cut and the type of cutting operation in which it will be used.

There are three main types of semi-chemical fluids: plain fluids, which have no added fat, super-fatted fluids, which have animal fat or vegetable oil added, or extreme pressure fluid, which contains chlorine and sulfur to add to the fluid’s lubricating qualities.

Semi-chemical fluids are ideal for jobs that require either cooling or lubricating. They work particularly well with non-ferrous metals and, in addition, they won’t stain your metal workpiece.
