PRODUKTINFORMATION Chesterton 386 Grinding Fluid is a full synthetic premium coolant designed to provide maximum productivity and the highest g-ratios with minimum downtime due to wheel loading, sump changeout and selective dragout of key performance additives. Low foaming and oil free, the product is ideally suited for all grinding applications including the high-pressure demands of centerless grinding. Often, when conventional soluble oil emulsions are used throughout the shop, they are also applied to grinding applications. This results in a much greater wheel loading than is necessary due to swarf entrapment within the oil emulsion particles. Wheels then have to be dressed more frequently to restore performance. In addition, because the friction generated during grinding is well in excess of typical cutting applications, it is more important than ever to have the most efficient heat transfer possible. A full synthetic accomplishes this far better than any product containing oil.
