In order to validate the influences that MQL(minimal quantity lubrication)brings to the tool wear and surface roughness, a MQL system was developed. It used the difference of pressure that caused by the compressed air flow through the decrescent areas to imbibe the cooling fluid in the box, and transported it to the nozzle for atomizing. The application in milling high-strength steel was also investigated. The experiment indicates that MQL has obvious predominance compared with dry and traditional cooling method, it can efficiently reduce the tool wear and keep the surface roughness at a low level, especially in the machining of high spindle rotating speed,big depth of cut and fast feed rate. It also has the characteristics such as the simple structure, the less dosage of cooling fluid and the less pollution to the environment. The experimental results were analyzed elementarily.
