Abstract
MQL (Minimum Quantity Lubrication) machining method attracts more and more attentions in production facilities for energy conservation and environmental protection. This innovative way of machining utilizes small amount of lubrication oil and compressed air instead of much water soluble coolant. Our "MQL Collet System" is most suitable for MQL machining method. Collet has 6 oil-jet splay nozzles in internal diameter for securing sufficient amount of lubrication oil in use of a small diameter tools and high precision aluminum machining. We introduce MQL collet system based on semi-dry actual cutting examples.
