Electrostatic atomization minimum quantity lubrication machining: from mechanism to application

Abstract Metal cutting fluids (MCFs) under flood conditions do not meet the urgent needs of reducing carbon emission. Biolubricant-based minimum quantity lubrication (MQL) is an effective alternative to lubrication. However, pneumatic atomization MQL has poor properties, which detrimental occupational health. Therefore, electrostatic requires preliminary exploratory studies. systematic reviews are lacking in terms capturing current research status and development direction this technology. This study aims provide a comprehensive review critical assessment existing understanding MQL. can be used by scientists gain insights into action mechanism, theoretical basis, machining performance, First, equipment, eco-friendly media (biolubricants), empowering mechanisms presented. Second, advanced heat transfer biolubricants revealed quantitatively comparing with MCF-based wet machining. Third, distinctive wetting infiltration MQL, combined its unique mechanism method, compared those Previous experiments have shown that reduce tool wear 42.4% metal improve machined surface R 47% Finally, future directions, including improvement coordination parameters equipment integration aspects, proposed.
