On the Wear Comparative Analysis of Cutting Tools Made of Composite Materials Based on Polycrystalline Cubic Boron Nitride when Finish Turning of AISI D2 (EN X153CrMoV12) Steel

Resumo

This study presents the results of research on the condition of low content polycrystalline cubic boron nitride cutting tools (cBN-L) when finish turning of hardened AISI D2 tool steel. The least changes in the condition of wedges throughout the investigated turning feeds were observed for the composite cBN020 whereas the highest wear intensity was found for the composite cBN200. For all researched cutting materials, abrasive wear, as well intense adhesion were observed.
