The correct turning tool material selection could help improve the pcd tools machining efficiency.

A high-quality cutting or turning tool can not be separated from high-quality tool materials. The quality of tool materials directly affects the quality of the machined surface, the efficiency

of cutting, the life of the tool, etc. High-quality tool materials should have: high hardness, high wear resistance and sufficient strength and toughness, high heat resistance, good material 

quality, economy, cutting performance and other good performance!

As the hardest substance in nature, diamond is used for tool turning with extremely high hardness, wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity,

low thermal expansion coefficient, and low affinity with non-ferrous metals.
