对１２０ｍｍ大尺矩形花键铲齿铣刀进行了超低温处理，对刀具寿命影响进行了实验研究。现场使用表明，刀具使用寿命成倍提高。超低温处理是提高刀具使用寿命的有效措施
The 120mm large-scale rectangular spline cutter tooth was cryogenic treatment, the impact of tool life were experimentally studied. Field use shows that tool life increased exponentially. Cryogenic treatment is an effective measure to improve the tool life
