2.25Cr-1Mo-0.25V steel is the material of key parts of major equipment in petroleum and chemical field. Aiming at its unworkability and low heavy cutting tool life, at first, the tool life comparative experiment of cutting 42CrMo steel, 2.25Cr-1Mo-0.25Vsteel and 45 steel was carried out. It was found that process ability of 2.25Cr-1Mo-0.25Vsteel was the worst, the second was 42CrMo steel. And the tool life of cutting 45 steel was 2 times more than that of 2.25Cr-1Mo-0.25Vsteel. Then the comparative experiment of different tool life of cutting 2.25Cr-1Mo-0.25Vsteel was made under the condition of heavy cutting. The service life of heavy cutting tool XF8 was significantly higher than that of YT15. At last, the factors affecting the service life of heavy cutting tool were analyzed, in order to provide basis for improving heavy cutting tool life of 2.25Cr-1Mo-0.25V steel. |
