将MQL应用于铝合金螺旋进给铣孔加工。在没有切削液的情况下，很难在铝合金上钻孔，因为与刀具的粘合会导致切屑卡住、刀具折断或精度降低。采用螺旋进给铣削，实现了断续切割，降低了切割温度，缩短了切屑长度，避免了孔内卡屑。结果表明，采用MQL螺旋进给铣削与钻削加工相比，形状误差减小，毛刺形成减少，加工温度降低，切削力减小。MQL螺旋进给铣削的形状误差与注水冷却时的形状误差相当。在这种情况下，随着主轴转速的变化，影响工作环境的5μm以下的小雾粒数几乎不变。与注水冷却剂相比，MQL转速在20000分-1以上时，分散的雾粒数较少。
MQL is applied to the helical feed milling hole-making process of aluminum alloy. It is difficult to drill on aluminum alloy without cutting fluid because the adhesion to the tool leads to a chip jam, the tool breakage or low accuracy. By employing the helical feed milling, cutting temperature will decrease, each chip length will become short and a chip jam in a hole will be avoided, because the intermittent cutting is realized. As a result of employing the helical feed milling with MQL, it was shown that the shape error is decreased, a burr formation is decreased, machining temperature becomes low and the cutting force becomes small comparing with drilling process. Shape error by helical feed milling with MQL is comparable with that with flood coolant. In this case, small mist particle counts under 5μm, which affects working environment, are almost constant if the spindle speed varies. Scattered mist particle counts are less when MQL is employed over 20000 min-1 spindle speed comparing with the flood coolant.
