Minimum Quantity Lubrication Technology (MQL) is a long discussed and debated technology in Metalworking Fluid industry over the years.  Advocates consider this technology as an alternative to get rid of conventional MWF problems like maintenance, separation, filtration and disposal.  Others believe in conventional MWF technology for thermal stability of the cutting tool and work piece, and better flushing ability.  MQL is often preferred for applications like milling and drilling.  Unist explains this technology with their expertise in turning operations through a white paper.
