Problems solved by technology

[0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators. In order to solve these problems, some progress has been made in the research of quasi-dry cutting technology recently. The quasi-dry cutting technology solves the problems of large amount of lubricant usage and serious pollution, but the research of quasi-dry cutting oil is mainly for lubrication and cooling. The problem can not be solved well, especially there are still some problems in its biodegradation and environmental protection

Abstract

The invention provides biodegradable quasi-dry cutting oil. The biodegradable quasi-dry cutting oil is characterized by being prepared from raw materials containing lecithin, wherein the content of lecithin in weight percent is 1-3%. The biodegradable quasi-dry cutting oil prepared according to the invention can be used together with a quasi-dry cutting device cooperatively, so that the consumption of cutting fluid can be lowered by over 95%. Therefore, the energy saving and emission reduction effects and the environmental protection effects are remarkable.
