Unlike the water miscible fluids which are designed to dissipate heat, neat oils are formulated to reduce generation of heat. Improvements in tooling materials and coatings have led to use of ever-increasing cutting speeds for machining. Use of neat oils at high speeds pose challenges of retaining lubricity and fire hazards. Use of synthetic base oils have twin advantage of better lubricity and higher flash points but make the product expensive. An in between approach would be use of GTL base oils and additives which provide optimum results. Magnacool® offers range of grades with all types of base oils to cover complete spectrum of materials and applications.
