This study deals with the improvement of high-speed spindle through supply system. During high-speed spindle machining large amount of pressurized lubricant is usually supplied to cutting area. From view point of the environmental protection, recently, the minimum quantities of lubrication system (M.Q.L) has been developed and applied to the metal cutting progress. When the spindle rotates at high speed, the mist flow is, however, blocked out from the machining area by the high-speed circular airflow. The spindle through coolant supply method is effective to supply the oil mist to cutting area in high speed machining. The oil drops are separated from the mist flow due to the centrifugal force during high-speed rotation. In order to suppress the influence of centrifugal force, a special type of oil mist supply mechanism was also developed and installed to the draw-bar shaft of spindle system.
