At the minimum quantity lubrication (MQL) machining processes are defined,
which in unlike conventional wet machining with conventional coolants, using
less than 20 ml. coolant per hour.
The minimum quantity lubrication is a method of lubrication in metal cutting
processes in the production technology. It enables the application of a
lubricant film in the immediate vicinity the machining area.
The friction between the tool, the workpieceis controlled by the
lubricating effect reduced. Swarf and workpiece remain nearly dry and the
machine environment clean. Costly coolant maintenance and disposal costs
for used coolants be omitted.
The minimum quantity lubricationis used during milling,turning, threading,
drilling, deep hole drilling, reaming and sawing.
