Abstract: The 21st century is such an age in which the factories pursue for eco-machining and zero-emission produc-tion. Clearly, it is necessary to improve work conditions, save energy consumption and decrease operation costs. As far as mechanical machining, there exists a status of the maximal cycling use and emission of the traditional machining fluids harmful to operator health and production environments, in which the waste fluids are not only hard to dispose but also some economic burden to enterprises. To improve this status, the traditional machining fluids are substituted by the new machining fluids of oils on water (OoW), and many grinding experiments on a NC plane grinder are carried out and the grinding performances and applicable feasibilities are investigated, this method is possible.
