Can develop hybrid CBN and diamond grinding wheel

About PDC drill bits

PDC drill bit, also known as polycrystalline diamond compact drill bit, is an important tool used for oil and gas drilling and geological exploration.

It is composed of tungsten carbide body embedded with industrial grade synthetic diamond. These polycrystalline diamond compacts are precisely placed on the crown of the drill bit to optimize its contact and cutting effect with the formation rocks.

The working principle of PDC drill bits is that polycrystalline diamond compacts with extremely high hardness and wear resistance can shear and break rocks during the rotation of the drill bit, thereby achieving the goal of quickly penetrating the formation.

Application of Diamond Grinding Wheel for PDC Drill Bit:

Cylindrical Grinding of New Drill Bit:

After welding the PDC on the body of drill bit, in order to ensure the accuracy of the cylindrical diameter of the drill bit to achieve cylindricity and prevent the drill bit from swinging during drilling, should use diamond grinding wheel to grind the outer diameter of the drill bit and the out PDC.

Considering the high Impact and wear during the grinding process, we choose the hybrid diamond abrasive and optimized the bonding agent, greatly improving the service life and efficiency.

Sharpening Re-Welding Drill Bits:

After the new PDC is welded on to the drill bit, both the old and new PDC are embedded in the drill bit at the same time.

The outer diameter of the drill bit is inconsistent and needs to be dressed. Clamp the repaired drill bit onto the cylindrical grinder and use resin bond or vitrified bond diamond grinding wheel to perform cylindrical grinding.( because there are iron-based elements, diamond and CBN hybrid grinding wheel wheels can be used.)

Handheld grinder and pneumatic grinder can be used to remove the burrs on the drill bit during the repair process, obtaining the regular shape and size.

Parameters Of Diamond Grinding Wheel for PDC Drill Bit

In the process of drill bits shaping, 1A1 diamond grinding wheel for PDC drill bit should be used with high grinding quality and efficiency. In addition, during the production process of PDC drill bits, resin bond internal diamond grinding wheels are also required, with the highest demand for the diameter of 101.6mm.
