CBN: mainly used for processing hard steel and cast iron.
PCD chipping: mainly used for aluminum processing, also can process copper, plastic, non-ferrous metals, etc, with good chip effect.
PCD-(Polycrystalline Diamond) is mainly used in aluminum processing, but also can process copper, brass, plastic, non-ferrous metals and so on.
Feature :
CBN:
It has strong impact toughness and fracture resistance, high metal cutting efficiency, and workpieces above HRC60 are not easy to chip.
CBN itself has high hardness, and the tool life is 10-20 times that of cemented carbide tools. It is suitable for processing high-hard workpieces above HRC45.
PCD/PCD chipping:
Strong wear resistance, the processed workpiece has a good finish,
Stable machinability, Mainly used for finishing and finishing operations
