Abstract
The performance of liquid lubricants employing nano-additives in minimum quantity lubrication (MQL) during the machining process has garnered significant attention in recent years. Nano-additives, due to their unique properties and characteristics, have demonstrated potential in enhancing the lubricating properties of conventional fluids used in MQL. These additives, typically ranging from nanoparticles to nanofluids, offer improved lubricity, reduced friction, and enhanced heat dissipation, thereby leading to better machining performance, extended tool life, and improved surface quality of machined components. By reducing the amount of lubricant used while maintaining or even enhancing performance, MQL with nano-additives not only addresses environmental concerns associated with excessive fluid usage but also contributes to cost savings and increased productivity in machining operations. However, challenges such as dispersion stability, compatibility with base fluids, and cost-effectiveness need to be carefully addressed to fully realize the potential benefits of incorporating nano-additives into MQL lubricants for machining applications. Ongoing research and development efforts in this field aim to further optimize the formulation and application of these advanced lubricants to meet the ever-evolving demands of modern manufacturing processes.
