Coring drill bit uneven distribution of the cutting surface of the teeth and flutes

Therefore, in the coring process, to ensure diamond cutting teeth rational flow of fluid around to adequately wash and cool the drill bit is very important. Coring drill bit uneven distribution of the cutting  polycrystalline diamond  tooth and the flute, the number of  cubic boron nitride g from a few to a dozen, the jet at the bottom of a very tight space constraints and irregular wall turbulence produces a very complex flow, a method of  synthetic diamond  analysis of this complex flow field distribution is almost impossible, and the flow field of the structure and properties of structural optimization was carried hydraulic drill, improving the basis for cleaning and cooling effect.
