通过切削试验 ,研究了纳米TiN改性的TiC基金属陶瓷刀具在切削 40Cr和正火态 45钢时的切削性能和失效形式。结果表明 ,该种刀具有良好的切削性能 ,可用于较高速度下钢的切削 ,其主要失效形式为磨损。
Through cutting experiments, the cutting performance and failure modes of TiC-based TiC-based cermets cutters for cutting 40Cr and normalized 45 steel were studied. The results show that this type of tool has good cutting performance and can be used for cutting steel at higher speed. Its main failure mode is wear.
