PCBN (cubic boron nitride)
Aug. 07, 2021
Polycrystalline cubic boron nitride - English abbreviation PCBN (cubic boron nitride)
CBN tools generally process Cast Iron and steel parts!!! Ninety nine percent.
Performance characteristics of PCBN tool:
1: High hardness and wear resistance;
2: High thermal stability and high temperature hardness;
3: High chemical stability;
4: It has good thermal conductivity
5: Low friction coefficient;
PCBN tool is suitable for high speed and ultra-high speed cutting technology
PCBN tool is most suitable for high-speed cutting of cast iron, hardened steel and other materials.
Finish machining of quenched hardware (hardness above HRC55); It is not recommended to process nodular cast iron!!!
PCD (polycrystalline diamond)
Polycrystalline diamond - English abbreviation PCD（ Synthetic Polycrystalline Diamond is commonly used)
Characteristics of PCD tools: high hardness, high compressive strength, good thermal conductivity and wear resistance, which can obtain high machining accuracy and efficiency in high-speed cutting.
PCD tools generally process aluminum alloy.
