Study on Bionic Diamond Bits for Drilling Superhard Materials

Abstract:

With diamond particles, metal powders and a special soft material as raw materials, this paper introduced some diamond bits to drill the superhard materials such as granite. Besides, the biology non- smooth theory was applied to the design of bit, and a new type of bit which is called bionic bit was introduced about its principle and manufacturing method. Numerical simulations and field tests of bionic bits showed that the optimalizing non-smooth degree was the most important factor of the design of bionic bit. By ANSYS finite element calculation when the non-smooth degree is 12.6%, the drilling bit wear is the smallest, 63% less than the ordinary bit. This paper prepared four bionic bits with the non-smooth degree 13% and four ordinary bits to drill the granit in gold mine, the average life and drilling speed of bionic bits increased by 29.8% and 21.3% more than ordinary bits.
