The improvement of tool performance is closely related to the development of tool manufacturing technology. As advanced tool materials such as PCD become increasingly popular in the market, tool manufacturers will find faster, higher quality and more cost-effective ways to manufacture these tools. The integration of other processes (such as EDM) with traditional grinding techniques is a way to meet the challenge of making super hard tools using advanced technology.
1. The hardness of PCD is 8 to 12 times that of cemented carbide, and its hardness can reach 8000HV.
2. The thermal conductivity of PCD is 1.5 to 9 times that of cemented carbide, which is 700W / mK. Therefore, the heat transfer rate of the PCD tool is very fast.
3. The friction coefficient of PCD is generally very low, only 0.1 ~ 0.3, so PCD tools can significantly reduce the cutting force.
4. The thermal expansion coefficient of PCD is only 0.9×10^-6 ~ 1.18×10^-6, which is only 1/5 of that of cemented carbide. Therefore, the thermal deformation of the PCD tool is small and the machining accuracy is high.
