A spindle cooling technology that directly cools the rotating spindle near the front bearing is effective in achieving a high-precision, high-rigidity spindle for a machining center. In conventional spindle cooling technologies, the entire spindle is cooled, which results in high cost and low efficiency. The writer developed a spindle cooling technology in which cooling is concentrated only in the necessary areas, and thus realized a low-cost, highly efficient method of cooling.
