Serious issues in magnesium alloy machining are combustion of chips and generation of hydrogen gas. The chips may flam out when the magnesium alloy is machined with oil fluid or in dry condition. Therefore emulsion coolants for the magnesium alloy are developed to chill the machining point and to prevent generation of hydrogen gas. However, an environmental issue is increasing costs of the waste fluid treatments. In this paper, an eco-friendly machining system for the magnesium alloy with oil film on water fog cutting fluid (OoW) is developed. It is obtained that the hydrogen gas is hardly generated when OoW with new oil is sprayed on the chips of magnesium alloy. And, milling tests with OoW are carried out with the developed machining system. As a result, magnesium alloy parts with high accuracy can be produced safely by the eco-friendly machining system.
