How MQL Works

The aim of near dry machining is to replace traditional coolant and pure oil flood systems in a machining environment with an accurately controlled compressed air stream that carries minimal quantities of oil lubrication in an "aerosol" format to the cutting surface. This ensures lubrication of the cutting surface and allows for high performance machining.

Lubricating Aerosol is transported to the cutting surface in two ways:
 
- External Lubrication: oil is transported via an external nozzle to the cutting surface placed in the vicinity of the tool and workpiece.

- Internal or "through-the-tool" Lubrication: oil is transported through internal lubrication holes in the cutting tool.

The goal of MQL is to manage heat from cutting and lessen the friction caused by the process. Air blown along the cut along with vaporization of the fluid is what accomplishes this task. The difference between traditional lubricant and MQL is that there is less of a mess and no additional heat generated that tends to happen with coolant.
