Development of Grinding Fluids with Non-Chlorine Extreme-Pressure Agents Development of Grinding Fluids Soft for Environment Motohiko II, Hiroshi EDA and Takaichi IMAI This paper describes the development of grinding fluids that contain extreme-pressure agents of non-chlorine type and are soft for enviroment. The grinding performance of grinding fluids is measured by cylindrical plunge grinding in this case. The following experimental results are confirmed: (1) Grinding fluids excel in grinding
