The Influence of Minimum Quantity Lubrication System Parameters on Oil Mist Concentration in Turning Machining Area
Minimum quantity lubrication(MQL)cutting is a green cutting technology,but some oil mist particles will be suspended in the cutting environment under the action of high-speed airflow.Based on the mass analysis,the effects of lubricant consumption,intake pressure and spray target distance on the PM 10 and PM2.5 oil mist particles concentration around the machine were tested.The results show that the lubricant consumption is the most important factor influencing the oil mist concentration,and the small amount of liquid water present in the compressed air helps to reduce the oil mist concentration.The study of the oil mist concentration of the cutting environment in the minimum quantity lubrication provides a referential test basis for the development and use of cutting oils matching the minimum quantity lubrication process.(Charts6 Tables3 References 12)
