The rigid body of diamond bit refers to the middle part of the head of the drill below the body and above the screw. In the actual drilling engineering, there are a few rigid body cracking. There are many reasons for this phenomenon, the most important ones are the rigid body material, drilling operation and thought to cause three reasons. A brief analysis of the specific situation of these reasons.
The rigid body material
At present, the main material of the diamond bit rigid body in China is DZ50/DZ40/45# steel, among which the most commonly used is DZ40, and its cost performance is the highest. But if some manufacturers apply inferior steel than 45# steel is the raw material, it is very easy to reproduce the situation of rigid body cracking, in fact, it is very unwise to apply inferior steel, because a good rigid body and inferior rigid body its cost difference is not more than $ 0.35. Therefore, generally no manufacturer will use inferior rigid body.
The drilling operation
This is the main cause of the crack of the rigid body of the diamond bit. When drilling some complex broken rock, pebble layer or rock fill layer, because of the large amount of broken stones piled up in the bit cavity, and the drilling machine applied up to 300kg of torque, if the bit does not tape or tape slowly at this time, The crushed stone in the inner cavity is easy to crack the rigid body of the drill.
Artificial operation
Because the drilling industry is mixed with fish and fish, it is not ruled out that some low-quality captains use artificial damage to crack the bit rigid body. The purpose of doing this is to hope to obtain the after-sales service of the manufacturer to replace the new bit.
In fact, each manufacturer has its own way to identify the cause of rigid body cracking, of course, rarely publicized. It is very easy to identify this kind of cracking phenomenon caused by artificial destruction. We deeply hate this kind of dishonest behavior. As a qualified drilling captain, we should think about how to improve the service life of diamond bit, rather than taking shortcuts to benefit ourselves at the expense of others.
