The CBN insert uses a super-hard material called cubic boron nitride through a synthetic insert.Features:
1. High hardness and wear resistance: The micro hardness of CBN single crystal is HV8000 ~ 9000, which is the second highest
hardness material known at present. The hardness of PCBN composite sheet is generally HV3000 ~ zd5000. Therefore, when used for
processing high-hardness materials, it has higher wear resistance than hard alloys and ceramics, which can reduce dimensional
deviation or dimensional dispersion in the processing of large parts, and is especially suitable for equipment with a high degree
of automation, which can reduce the change The knife adjusts the auxiliary time, so that its efficiency can be fully exerted.
2. It has high thermal stability and high temperature hardness:
The heat resistance of CBN can reach 1400 ~ 1500 ℃. The hardness at 800 ℃ is the normal temperature hardness of Al2O3 / TiC
ceramics. Therefore, when the cutting temperature is high, the processed material will be softened and the hardness difference
between the tool and the tool will increase. , It is beneficial to the cutting process, and has little effect on the life of the
tools weight.
Especially suitable for the auto part such as bearing race , processing material is powder metallurgy
