Would you be familiar with the PCD cutting tools and what about the PCD/CC cutting tools? it is the mixture of Poly Crystal Diamond and cemented carbide used as the main raw material.

Based on the features and advantages of PCD cutting tools, in order to improve the cutting blade’s tenacity and weldability, on the base of cemented carbide, one layer of diamond composite blade, about 0.5 mm to 1 mm, was sintered or suppressed on the tools’ surface.

PCD/CC cutting tools are made from welding manufacturing technique or pressing manufacturing technique, therefore they have good weldability and it is easy to take some heavy grinding, meanwhile, the cost of production is too much low. In recent years, it is widely used for processing.

However, you should clearly know that both the PCD cutting tools and PCD/DD cutting tools don’t have the sharp cutting edge and uniform finished surface as the monocrystal diamond cutting tools, therefore up to now, it can not be used to process some products with too much complicated geometrical shape such as end milling cutter and indexable cutting blade with chip breaker groove.
