The processing of PCD tools
The cutting edge geometry and final dimensions of the PCD tools are usually ground on CNC tool grinding machine. However, ultra-hard tools with polycrystalline diamond (PCD) cutting edges pose a challenge for grinding. In fact, grinding a PCD tip with the hardest diamond grinding wheel takes a lot of time and loss of grinding wheels. Faced with two substances of the same hardness and trying to use one to remove the other. The final result is that the wear rate of the grinding wheel almost reaches 1∶1 loss and it is too high.
Therefore, to improve the sharpening efficiency of PCD tools, mainly in the following aspects.
1.Enough rigidity and stability.
2.Unique grinding wheel swing mechanism.
3.Grinding force.
4. Fully supplied coolant.
