Description

technical field [0001] The invention relates to a continuous supply method of ultra-low temperature cutting cooling medium, in particular to a continuous supply method and device of liquid nitrogen. Background technique [0002] In recent years, the rapid development of high-performance processing technology has made it possible to process high-speed, high-efficiency, and precise mechanical products. However, how to further tap the potential of machine tools and cutting tools under the existing technical level of machine tools and cutting tools is still a technical problem in the industry. A large number of research and application examples show that effective cooling and lubrication is the main technical way to further improve the processing quality and processing efficiency of difficult-to-machine materials. [0003] Cryogenic cutting has always been considered as one of the important technical means to achieve green, efficient and high-quality machining of difficult-to-m...
