Spindle core cooling/under race lubrication

Makino's spindle core cooling and under race lubrication system is used to suppress spindle thermal distortion. This patented technology has a proven record of outstanding performance with Makino's high-speed spindles.

The spindle core cooling system circulates a large volume of temperature-controlled cooling oil through the center of the rotating spindle to cool it directly from the inside. With under race lubrication, the cooling oil circulated through the spindle flows through holes in the inner bearing races to lubricate the bearings as well.
