Kaiqiu Water Well Drilling Tools The quality of rock broken by the manufacturer’s diamond drill bit is closely related to the mechanical properties of the rock. It is very important to use different rock breaking methods for different rocks. At present, the commonly used rock breaking methods in drilling include shearing, ploughing, grinding and crushing.
　　 will produce different drilling effects for different rock breaking methods. In drilling, no matter what kind of rock breaking method is adopted, it is incomplete to say that it is all a certain rock breaking method, because the formation in drilling is ever-changing, and the drill bit is affected by various forces. The wear of the rock is also changing. Regardless of the changes, the effect of diamond drill bits is better than other drill bits when drilling in the formations below medium-hardness.

　　The advantages of composite flake broken rock:
　　1. Diamond drill bits and cemented carbide drill bits
The rock-breaking principle of the diamond bit is the same as the initial stage of cemented carbide drilling. This is because the cemented carbide has a sharp edge and high efficiency when the cemented carbide is initially drilled. However, because the cemented carbide is not wear-resistant, the blade will be quickly removed When it is flattened or the edge is broken due to uneven force, the cemented carbide does not break the rock in the form of shearing, but changes to the crushing method. The efficiency also drops rapidly, and the life of the drill bit is very low; and the diamond drill bit has a wear resistance of the diamond at the blade is much higher than that of the cemented carbide, and the drilling wear in the formation is very slow, and it can always keep the rock in the form of shear , The efficiency has little change, and the life span is longer.
　　2. Diamond drill bit and composite drill bit
As we all know, the composite disc drill bit uses the cutting method to remove the rock, and the polycrystalline diamond is very wear-resistant, but because the diamond particles are small, the area of ​​the composite disc is limited, and the amount of cutting edge is small, and each diamond can only wear 1/3 The left and right sides are separated, so the composite sheet cannot be pressed into the rock deeply to perform work, and the volume of broken rock cannot be formed, and the efficiency is not high; while the diamond bit concentrates the high wear resistance of diamond and the large cutting edge of cemented carbide. It forms the advantages of volume broken rock and high drilling efficiency.
　　3. Rock Button Bits and natural table-set drill bits
　　Natural surface-mounted diamond drills are used to break rocks in the form of ploughing, and the cutting edge is smaller than that of cemented carbide and larger than impregnated drills. When a new face-set drill bit is drilled, it has a sharp sharp edge, and it is easy to press in the diamond when it touches the rock. The drilling efficiency is also very high, but the sharp edge of the diamond continues to wear or fall apart over time As a result, the diamond gradually becomes a perfect round shape, and the drilling efficiency gradually decreases. However, since the hardness and wear resistance of natural diamond are much higher than that of cemented carbide, its efficiency decline rate is much slower, rather than the rapid decline like cemented carbide. Despite this, the drilling efficiency of diamond drills is still higher than that of surface-mounted drills.
