钛合金是一种难切削材料，用常规刀具加工时性能较差。在这篇论文中。一种新型刀具材料--无粘结剂立方氮化硼（BCBN）被用于高速铣削广泛使用的钛合金Ti-6Al-4V。研究了该刀具在铣削该合金时的性能和磨损机理。这种类型的刀具在高切削速度下表现出更长的刀具寿命。扫描电镜和能谱分析表明，BCBN刀具在高速铣削Ti-6Al-4V时的磨损机制主要为工件的粘附、磨损和扩散溶解。(C)2004 Elsevier B. V.保留所有权利。
Titanium alloys are difficult-to-cut materials, and the performance of conventional tools is poor when used to machine them. In this paper. a new tool material, which is binderless cubic boron nitride (BCBN), is used for high-speed milling of a widely used titanium alloy Ti-6Al-4V. The performance and the wear mechanism of the tool have been investigated when slot milling this alloy. This type of tool manifests longer tool life at high cutting speeds. Analyses based on the SEM and EDX suggest that adhesion of workpiece, attrition and diffusion-dissolution are the main wear mechanisms of the BCBN tool when used in high-speed milling of Ti-6Al-4V.
