MQL (minimal quantities of lubricant) was applied to grooving to clarify its performance in high speed and high efficiency cutting. When grooving a bar of carbon steel with coated carbides at high cutting speeds of 4 and 5 m/s, the corner wear and flank wear in MQL cutting were improved drastically as compared with dry and wet cutting. They decreased with increasing pressure of the compressed air even if the oil was supplied at a constant rate of 7 ml/h. In addition to the ordinary blow of the oil mist, the controlled blow for changing the blowing direction of oil mist through prolonged pipes along the flank face was applied to high efficiency grooving with a cutting cross section of 1.275mm^2. When the flow rate is the same, the controlled blow of oil mist reduced both the corner wear and flank wear of cemented carbides effectively.
