Tool wear and machining dynamics when turning high chromium white cast iron with pcBN tools
High chromium white cast irons (HCCI) with high hardness and abrasiveness owing to a particular combination of hard primary and eutectic carbides were used as workpiece materials for longitudinal turning with binderless cBN (bcBN) and high cBN (hcBN) tools. The materials with low and high Si content were used in as-cast and quenched states. Binderless cBN is prone to cratering and flank wear, whil
