Non-smooth surface structure theory is the theoretical basis of bionic PDC bits

Smooth surface structure is not typical soil animals have the following properties: adhesion, resistance slow, high strength, good wear resistance. First, Mole, earthworms, beetles and other soil animals typical example of the animal's bionic system.  synthetic diamond powder  structure theory is the theoretical basis of bionic PDC bits. Based on past experience, to bionics theory, combined with the smoothness of PDC bits bionic theoretical model development rules,  cubic boron nitride principle. This article mainly on bionic experiment type PDC bits are introduced, while the traditional analysis and comparison of PDC bits, which can show that when the drill rock drill bit wear, friction, wear resistance and non-smooth surface structure and other properties.
