Near Dry Machining (MQL) is a Key Technology for Driving the Paradigm Shift in Machining Operations

摘要

Near-dry or minimum quantity lubrication (MQL) machining eliminates conventional flood coolant from the machining processes. In doing so, MQL reduces oil mist generation, biological contamination of coolant, waste water volume, costs for capital equipment and regulatory permitting. MQL also improves recyclables and transportation of coolant contaminated chips. Although MQL machining technology has several advantages compared to wet machining, widespread implementation will require a paradigm shift among end users, machine suppliers and cutting tool suppliers. Successful implementation of MQL machining requires a high technical understanding and a solid infrastructure to support maintenance and ongoing continuous improvement.
