Abstract:

Experiments were conducted to determine the effect of mineral oils and a number of cutting oil-mineral oil solutions on solid tool steels, solid carbide inserts, and powdered carbides at elevated temperature. Other metallic powders such as zirconium boride and chromium boride were included in the investigation. Mineral oils alone did not react with the tool steels. However, when combined with cutting oils and cutting-oil concentrates, insoluble films formed on the polished surfaces. VV-O-241 Grade 2 mineral oil appeared to attack the polished surface of the carbides tested, whereas technical grade paraffin oil had little effect. Combinations of pure mineral oil, cutting oils, and cutting-oil concentrates appeared to attack the carbide specimens to a greater extent than the VV-O-241 Grade 2 mineral oil. Results obtained with the powders showed a gain of weight in most powders treated. This indicated that some reaction did occur however, the mechanism of the reaction was not determined. Test procedures are described and results discussed. Author
