Oil-air, oil-mist or micro-fog and oil-jet lubrication are used as lubricating system for high-speed machining center which is applied for the purpose of high-speed work and heavy duty processing. Injection hole leading to lubrication nozzles gives a resistance for the feed of the lubricant within air, but the countermeasure has not given concerning the air flow. Improvement must be given for the lubrication and cooling efficiency in order to increase in the rotational speed of spindle supporting by rolling bearings. This report describes some effects of two nozzle types which are debarred and polished by abrasive fluid or not, and of the supplied cooling air in - 20℃ for the purpose of the decrease in temperature rise of the bearings. Main results are as follows : (1) The debarred and polished nozzle is more effective than without polishing concerning the mass flow rate of air in any pressures and lubricants. (2) Approach to the cooling air direct injection is effective for the temperature rise of the bearings. (3) Even if the perimeter of bearing is kept lower than the room temperature, the dew and freezing condition for the bearing have not occurred under - 20℃ supply cooling air. (4) The temperature difference occurs on bearing outer ring when one cooling-nozzle is used, and the temperature difference of the bearing outer ring is changed by the distance between the cooling-nozzle and the bearing face.
