Effects of Minimum Quantity Lubrication (MQL) in …

20.07.2016· The MQL grinding could be used in higher metal removal rates with enhanced surface finish and lower grinding forces. Due to efficient penetration of oil-mist in the contact zone, MQL considerably reduced the friction coefficient and tangential forces as compared to the conventional grinding. It also reduced the normal grinding forces in case of hard steel. However, for soft steel, higher value of normal forces was recorded under MQL in comparison to fluid cooling condition. MQL ...

What is MQL? (the basics) | Minimum Quantity Lubrication

The concept of MQL is fundamentally different than that of flood coolant and this can be a large stumbling block to machinists who are new to MQL. The use of flood coolant is incredibly basic. As long as relatively clean coolant ‘floods’ the interface of the cutting tool and workpiece, the heat generated by machining operations is kept at bay. This process works (another reason it is ...
