Mitsubishi Materials India Private Limited has introduced BC8210, a new coated CBN grade developed for turning hardened steel. The new grade is suitable for continuous and light interrupted cutting applications.
BC8210 is designed to deliver long tool life through its high wear and fracture resistance, helping to provide a stable machining process during high-speed cutting.
The company stated that large crater wear during the turning of hardened steel is a common challenge that can lead to edge chipping. BC8210 offers excellent flank and crater wear resistance, while its improved chipping resistance contributes to a more stable machining process.
Main features of BC8210
1. The combination of the newly developed AlCrSiN-base coating that absorbs machining impacts, with the TiAlSiN-base coating, which has excellent wear resistance, provides stable wear resistance in continuous through to low interrupted cutting conditions.
2. By dispersing a new ultra micro-particle and heat resistant binder onto the CBN base, both chipping and crater wear are suppressed which promotes a longer tool life.
