2. About High Manganese Steel
Normally CBN only works when the steel component is hardened, with a hardness above 50 HRC. One exception are the so called austenitic high manganese steels. These are steels with a manganese content of 11% or more, originally invented by Sir Robert Hadfield. In its original state, the material is usually around 250 HB, but the hardness is increased significantly through deformation hardening when used, without any loss of toughness. The hardness is also very difficult to measure with high accuracy due to the high level of work hardening.
The application areas for these materials are in the mining industry, such as in components for cement mixers, rock crushers, railway switches and crossings, crawler treads for tractors, teeth for excavators and other high impact and abrasive environments,the typical component is crushing cone.
3.CBN Insert Replace Carbide Insert Application
When using carbide has to be very low, cutting speeds in the range of 20 to 30 m/min is normal. By instead using CBN, cutting speeds can be increase to 200 m/min, which significantly improves productivity.
One typical application where Halnn Tools has a long experience and has been very successful is turning of crushing cones.
