Experimental Study on Efficient Bionic Cutting Teeth

Abstract:

Under the guidance of the bionic theory, taking mole claws as bionic prototype, the high efficiency and wear resistance properties obtained from long-term evolution are introduced. CVD polycrystalline diamond cutters were selected as cutting unit and efficient bionic cutting teeth were prepared with vacuum hot pressing sintering process. By the contrast tests, the results reveal that the wear resistance of efficient bionic cutting teeth is increased by 23% compared with the conventional PDC teeth; the cutting efficiency is 1.49 times that of the conventional PDC teeth and 48% higher than bionic PDC teeth. It preliminarily proves the feasibility of the process of efficient bionic cutting teeth, which lays a solid foundation for further study on efficient cutting bit.
