Synthetic machining coolants are made from polymers and other addiitves. Synthetic coolants lend themselves well to grinding and light-duty machining. Synthetics work great for grinding because they allow for swift settling of the small fines created during grinding. Grinding fluids should be cleaner than machining fluids because they cover a larger work area and can splash more than a machining operation. Whereas water-soluble oils will absorb tramp oils, synthetics typically will reject the oils - allowing them to be skimmed from the surface of the metalworking fluid. In some applications, this feature allows synthetics greater longevity in the sump. Many synthetics work well for machining all metals and some of the newer and more expensive synthetics can approach the tool life of water-soluble oils. The disadvantage of synthetics is that some components such as lubricants and rust preventives can be used up before the rest of the metalworking fluid.
Manufacturers like Janed formulate different grades of synthetic machining coolants, so that there are coolants available for all types of machining operations. Each coolant product can have low to high cost ingredients. Typically, the higher the price of the product, the better performance it will give. Just because a metalworking fluid is lower in price does not mean that the customer will save money in the long run, because tool life and maintenance can be affected greatly by metalworking fluids.
