The goal of near-dry machining is to replace the traditional coolant and pure oil overflow systems in the machining environment with a precisely controlled stream of compressed air that carries a minimal amount of oil lubrication in an "aerosol" format to the cutting surface. This provides lubrication of the cutting surface and allows high performance machining.

Lubricant Aerosol is transported to the cutting surface in two ways:

- External Lubrication: Oil is transported via an external nozzle to the cutting surface located close to the tool and workpiece.

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

Dropsa has developed a revolutionary technology for both of these processes. MiQueL and MaXtreme
