Modern, Extreme Pressure-Type, Water-Base, Metal-Working Lubricants

摘要

Preliminary experiments were conducted to establish parameters for the development of a test or tests so that performance characteristics of metal-working lubricants could be evaluated. Selected proprietary cutting-fluids were compared for performance in the Falex and in the Shell four-ball machines. The water and volatile content of each cutting-fluid concentrate was determined. Infrared spectra were obtained and data interpreted for each of the dehydrated, devolatilized concentrates. The presence of sulfur and metallic constituents in the concentrates was established. A modified Falex test procedure is outlined. A number of infrared spectra of typical compounds, used in the cutting-fluid formulations, are presented. Results of testing and comparisons indicate the complexity of the problem and the need for development or a workable and reproducible performance evaluation procedure. (Author)
