Machining Coolants [Soluble Oils, Semi And Full Synthetic Oils]

Machine Coolants

Machining coolants are an integral part in all machining operations. Operations like turning, milling, drilling, tapping, and grinding all produce heat from the cutting friction. Coolants add lubricity, and the water content transfers heat rapidly away reducing the operating cutting tool temperatures. This reduction in heat increases tool life, and the lubrication improves surface finishes. They also aid in the flushing away of metal chips and abrasive material from the operating zone. When choosing a machining coolant, it is important to evaluate the metals being machined, and the benefits / weaknesses of each coolant type. Coolants fall into the following three categories: soluble oils, semi-synthetic oils, and synthetic oils.

Manufacturers like Janed formulate different grades of metalworking 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.

Types Of Machining Coolants From:



Semi-Synthetic
Semi-synthetic machining coolants are a compromise blend of synthetic coolants (polymers) and water-soluble oils. Both of these types of coolants have advantages and disadvantages, and semi-synthetic coolants combine most of the advantages, and minimizes the disadvantages in machine coolants. Semi-synthetics are less likely to cause rust than synthetics, because of their oil content. They allow less bacteria growth than water-soluble oils, because the oil content is much lower. The semi-synthetic blends provide excellent cooling and lubrication properties while minimizing bacteria formation and rust prevention.

Synthetic
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.
