An Appearance of Rust-Preventive Properties by Optimum Interfacial tension in Oil on Water for Cutting Process

摘要

Effective environmental measures including less waste fluid, resource saving, energy conservation and environmentally friendly workplace, in addition to highly efficient and accurate operation, have remained a critical issue in cutting processes. As one of the measures, MQL(Minimum Quantity Lubrication) which supplies workpiece interface a minute quantity of cutting fluids in the form of a fine oil mist has been put to practical use and contributed a great deal to reducing the lubricant use to about 1/20 of its original quantity.[1] This paper deals with studies to find an effective cutting fluid applied to OoW(Oil on Water), focusing on a combination of a nonionic rust inhibitor and ester oils.
