What is CBN cutting tools?

19 June 2023
CBN cutting tools are currently the most advantageous cutting tool materials when processing high-hardness and difficult-to-machine ferrous metal materials, and are necessary cutting tools for precision and ultra-precision machining in the future.
CBN Inserts
CBN (cubic boron nitride) is converted from hexagonal boron nitride (white stone ink) under high temperature and high pressure. It is a kind of super hard tool material developed after artificial diamonds. CBN is a nonmetallic boride, its hardness is second only to diamond, far higher than high-speed steel and hard alloy, so after making a tool, more suitable for processing hard alloy tool processing immovable material.
CBN cutting tools have excellent high-temperature hardness - up to 2000 ℃, although Brittle than carbide inserts, but significantly improved impact strength and crush resistance compared to ceramic inserts. 
In addition, some special CBN inserts can resist the chip load of large-gauge roughing and can withstand the impact of interrupted cutting and the wear of finishing and cutting heat.
These characteristics can meet the roughing of hard-to-machine materials such as hardened steel with CBN inserts.
Solid CBN Inserts
The CBN cutting tools are suitable for processing materials: gray cast iron, various wear-resistant cast iron, cast steel, high hardness materials (such as hardened cold work tool steel, high-speed steel, bearing steel, powder metallurgy steel, high strength steel, high manganese Steel, high chromium cast iron, white cast iron, austenitic iron, cemented carbide, etc.
