Enclosure Exhaust System Design for Oil Mist Control
Oil mist is created by the heat of the machining operation vaporizing the fluid, high-pressure sprays atomizing the fluid, and the rotating action of the tool slinging droplets into surfaces that create smaller droplets. In addition to coolants, other oils can find their way into the cutting fluid solution through leaks in the equipment's hydraulic oil system or excess lubricant from machine rails. These trap oils have a greater tendency to mist than the fluids used in coolant mixtures.
