Bionics is developed between the biological sciences and technical sciences an important emerging interdisciplinary , the bionic technology inexhaustible power and the source of the original technological innovation is an important means to develop high-tech . After a long period of natural selection and evolution , the biological optimization excellent morphology and material surface is created by human beings advanced technology to emulate objects , and provides a natural learning blueprint for human beings . Soil animals (such as dung beetles , mole crickets, pangolins , etc. ) live permanently in the soil and rock , after millions of years of evolution , the surface soil-engaging parts showing pits , convex hull , such as scales, corrugated smooth morphology it not only has a good reduction in adhesion, to reduce the resistance function, but has a very high wear resistance and regeneration function . Mimic the characteristics of the organism table bionics technology applied to the design of the drill , in theory, can solve the short life of the drill bit , drilling efficiency and drilling process \In the formation of the drill on the non- smooth surface drill charging method of implantation of certain media , divided into the hard spots implantation and soft particle implantation in the the hard particle implantation bottom during drilling in lip surface to form raised , soft particle implantation to form pits . This article with the structure of the diamond drill bit design , manufacturing theory and technology closely integrated , non-smooth groove theory used in diamond drill , developed on the basis of the non- smooth surfaces forming method bionic impregnated diamond bits kinds of non-smooth new trench impregnated diamond bits , the aim is to provide the A in drilling hard the slipping formation of efficient , wear broken rock tools . Design two different forms of non - smooth diamond groove bionic drill through geometric pressure test speed of 450rpm, WOB 600kgf trench bionic drill drilling efficiency is the ordinary the bionics bits of 5.6 times , 29.7 times the ordinary drill . Other drilling parameters under the conditions of efficiency are superior the ordinary the bionics bits and ordinary drill . However , the strength of carcass strength is not enough to overcome the problem currently no .
