T1 - Comparison of the life-span of NbC-Co and WC-Co inserts during different machining operations on 100Cr6 (SAE 52100) bearing steel T2 - Proceedings of the International Symposium on Wear Resistant Alloy for the Mining and Processing Industry N2 - The aim of the study presented in this paper is to highlight the potential of niobium carbide cutting tool inserts for machining and to compare their performance to commercially available tungsten carbide inserts. In this work, a comparison between a conventional Wc-Co insert and NbC-Co inserts was carried out under hard machining conditions on specimens made of 100Cr6 bearing steel grade (SAE 52100).
