540 Development of a Multifunctional Fluid for Environmentally Friendly Machining

概要

In manufacturing processes, the environmental issues concerning lubrication are not merely cutting fluids. Machine tools generally necessitate a variety of lubricants for its individual sliding and rotating parts, so that the application of environmentally acceptable lubricants to machine tools is of great significance. Further, since some of those lubricants are often contaminated with cutting fluids and disposed without adequate separation treatments, it must certainly be useful to develop a multifunctional fluid which is applicable to both machining and other lubricating parts. In this study, therefore, a synthetic polyol ester is proposed as a base candidate of such multifunctional fluids. The candidate polyol ester can satisfy the cutting performance and secondary characteristics necessary for MQL lubricants. This ester is combined with a highly effective extreme pressure additive to prepare a potential lubricant as a multifunctional fluid. The developed fluid can demonstrate the excellent performance in MQL machining and the practically sufficient abilities for hydraulic and slideway lubrication.
