Grinding technology with minimum quantity lubrication technology is a new type of environmentally friendly and efficient processing technology. It has the characteristics of less cutting fluid and low cutting force, and is conducive to the maintenance of the tool and can effectively improve the quality of the workpiece. However, the cooling performance of the high?pressure air flow of the grinding technology with minimum quantity lubrication is very limited, which can not meet the need for cooling in the grinding zone. The traditional casting cooling technology can meet this demand by using a large amount of grinding fluid. In this paper, the research background, development status and latest achievements of micro?lubrication technology were reviewed, which lays a theoretical foundation for further study of the characteristics and principles of these special grinding technology with minimum quantity lubrication..
