| Abstract: | The reason of premature failure of the finger-shaped milling cutter for used in machining cement machinery big modulus gear was analyzed in terms of the chemical composition, matrix structure, hardness and heat treatment process. The results show that the premature failure of the finger-shaped milling cutter results from the excessively low hardness and poor wear resistance which arise from excessively high tempering temperature. |

| Keywords: | finger-shaped milling cutter high-speed steel tempering softening |
