MINIMUM QUANTITY LUBRICATION TURNING USING TOOLS WITH OIL HOLES

摘要

For ecological and economical reasons, the MQL (Minimum Quantity Lubrication) machining, in which a very small quantity of oil is supplied to the cutting point, attracts a great deal of attention, because it improves the cutting performance. Therefore several investigations on the effect of MQL have been performed, and most of them are focused on the reduction of tool wear and improvement of surface roughness of work materials [1-3].
