As high-speed machining offers numerous benefits, so it is increasingly penetrating into many areas of industry. At the same time, regulations aimed at controlling environmental pollution are becoming stricter ahd stricter, along with rising costs of cooling lubricants. From this point of views, minimal use of lubricant(MQL) is strongly required. The realization of a technology incorporating both high-speed machining features and MQL is therefore an important task. The spindle-through coolant supply method is able to effectively supply the oil-mist to the cutting area in high-speed machining. However, the high-speed rotation causes separation of oil mist in the rotating spindle, and the amount of oil-mist supplied to the cutting area decreases. This phenomenon is said to that a centrifugal force that occurs around a high-speed rotation becomes a cause. However, this phenomenon isn't proved by an experiment and is no better than a guess. In this study, this phenomenon is proved by the numerical analysis.
