Because the diamond particles of the diamond drill bit are fine, the volume crushing effect on rock strata is small, the actual rock crushing mechanism is similar to that of grinding a workpiece by using a grinding wheel, namely, a workpiece (rock at the bottom of a hole) is scribed and ground by using more and smaller hard particles (diamonds) on the lip surface, a tire body is continuously worn along with gradual wear and disappearance of the original hard particles, and new hard particles are exposed to continue working. In fact, the diamond bit is also consumed in the high-speed grinding work, and needs to be replaced in time, and the existing diamond bit is welded in an integrated mode, so that the subsequent maintenance needs to be replaced integrally, and the cost is increased.
