Hard materials Hybrid grain structure (KBN05M)

Mixed structure of micro grain CBN and coarse grain CBN

CC KBN05M

CBN that possess High hardness, toughness and thermal resistance characteristics CBN structure KBN25M KBN10M KBN35M

Coarse grain CBN

FinishingMediumRoughing
ContinuousLight interruptionInterruptionHeavy interruptionHeat diffusion is promoted by coarse grain CBN

Micro grain CBN High thermal conductivity KBN05M is 1st recommended grade for a wide range of application from continuous (high speed finishing) to interrupted machining. KBN25M: High stability for general machining KBN35M: Honeycomb structure CBN (Superior fracture resistance in heavy interrupted machining)
