MQL Application in High-Speed Turning Bearing Steel

Abstract:

Green high-speed cutting is one of the main development directions of advanced processing technology.The defects of the traditional cooling and lubrication conditions and the deficiencies of external MQL (Minimum Quantity Lubrication) were analyzed in this paper. A new way of cooling and lubrication named internal MQL was highlighted, and an internal MQL system applied to turning was researched and designed. By high-speed turning of bearing steel GCr15 under different cooling lubrication conditions as dry turning, external and internal MQL, the comparative study of cutting force and surface roughness was carried out systematically. The results showed that the internal MQL has a comparative advantage, showing a good application prospect.
