In this research, a new type of oil-mist supply (MQL) mechanism was developed and installed to the draw-bar shaft of the high speed spindle system of a machining center. The performances of proposed mechanism was experimentally and numerically analyzed. The results obtained are summarized in the following.(1) By the non-rotating mechanism proposed in this study, the oil-mist separation in the spindle through pipe was effectively suppressed and the oil-mist was successfully supplied to the top of the tool during high-speed spindle rotation .(2) Comparing with the complete dry cutting and usual wet cutting, the MQL system with the stationary pipe insertion mechanism provides a good cutting performance in drilling and milling tests.(3) The behavior of oil mist in the high-speed spindle was numerically analyzed, and the oil mist adherence phenomenon due to centrifugal force was proved.(4) The effect of the stationary pipe insertion mechanism was also numerically analyzed and the effectiveness of the proposed mechanism was confirmed.

研制了一种新型油雾供油机构，并将其安装在加工中心高速主轴系统的拉杆轴上。对该机构的性能进行了实验和数值分析。所得结果总结如下。(1)通过本文提出的非旋转机构，有效抑制了主轴通过管道的油雾分离，并在高速主轴旋转过程中成功地将油雾输送到刀具顶部。(2)与完全干切削和通常的湿切削相比，固定式插管MQL系统在钻铣试验中具有良好的切削性能。(3)对高速主轴内油雾的行为进行了数值分析，证明了离心作用下的油雾附着现象。(4)对固定插管机构的效果进行了数值分析，验证了该机构的有效性。
