The introduction of vegetable oil-based coolants in machining applications has made it possible to achieve quantum increases in overall performance. As a proven and tested technology, vegetable oils have been recognized as having superior lubricating properties since the 1960s. During this time, the process of stabilizing coolant emulsions that are based on water-miscible vegetable oils proved to be challenging, which meant that machining lubricant options were limited to mineral oil-based coolants containing various additives. Vegetable oil was used for the most part in straight oil applications.
Today, a new generation of emulsifiers and stabilizing agents has ...
