摘要

摘要: 聚晶立方氮化硼(PCBN)刀具是继聚晶金刚石刀具之后的又一种超硬刀具，以其独特的“以车代磨”、“硬态加工”、“干式切削”等方式被誉为21世纪的绿色环保刀具。PCBN刀具在金属切削方面具有广泛的应用，主要用来加工各种淬硬钢、耐磨铸铁等铁基材料。本文介绍了PCBN刀具成分、几何形状、切削参数等对其切削性能的影响，在此基础上分析了不同材料加工时刀具的主要磨损机理，还简单对比了硬质合金和PCBN刀具切削性能上的差异。

Abstract: Polycrystalline cubic boron nitride (PCBN) tool is another kind of superhard tool after polycrystalline diamond tool. It is known as the green environmental protection tool in the 21st century for its unique advanced cutting methods such as turning instead of grinding, hard machining and dry cutting. PCBN tools are is widely used in metal cutting, which is mainly used for processing various kinds of hardened steel, wear-resistant cast iron and other iron-based materials. This paper introduces the influences of tool composition, tool geometry and cutting parameters on the cutting performance of PCBN tools. On this basis, the main wear mechanism of cutting tools in machining different materials are analyzed, and the cutting performance differences between cemented carbide and PCBN tools are also briefly compared.
