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.
[0003] In order to solve these problems, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology solves the above problems such as large amount of lubricant used and serious pollution. At the same time, in order to make the micro-quantity lubricant used have relatively strong extreme pressure and anti-wear Sex and lubricity, excessive use of sulfur- and chlorine-containing additives that are not friendly to the environment, it is a meaningful research topic to study a micro-lubricant additive that does not contain sulfur and chlorine and has excellent extreme pressure and anti-wear properties. Since the boron-rare earth lubricating oil composition has relatively good self-repairing wear and antirust properties, the research on boron-rare earth lubricating oil composition materials is also of practical significance
[0004] The company's research group has studied rare earth borides as lubricating oil additives, and successfully applied for a related invention patent: intelligent repair micro-lubricating oil and its preparation method ZL201510955039.3, but the rare earth borides selected at that time were nano-lanthanum borate, boric acid Cerium, the prepared trace lubricating oil is actually a nano-suspension, and its application scope is mainly open gears, guide rails, bearings and other open environments that are lubricated with thin oil, and is not suitable for metal cutting processing technology
