近年来,随着CNC加工技术的迅猛发展以及数控机床的普遍使用,刀具材料也不断更新和发展,高速切削加工已成为现代切削加工中不可缺少的重要手段。高速切削加工的切削速度是常规切削的5～10倍,对刀具材料以及刀具结构、几何参数等都提出了新的要求,尤其是对刀具的材料有更高的要求,高速切削刀具的材料要具有高的强度、韧性和硬度,良好的热稳定性和热硬性、良好的高温力学性能、较小的化学亲合力和耐磨性。这里就针对高速切削的刀具材料和性能及其合理选择措施进行探讨。
In recent years, with the rapid development of CNC machining technology and the common use of CNC machine tools, cutting tool materials are constantly updated and developed. High-speed machining has become an indispensable and important tool in modern machining. Cutting speed of high-speed cutting is 5 to 10 times that of conventional cutting, and puts forward new requirements on the tool material, the structure of the tool and the geometric parameters. In particular, the material of the tool has higher requirements. The material of the high-speed cutting tool Has high strength, toughness and hardness, good thermal stability and thermosetting, good high temperature mechanical properties, less chemical affinity and abrasion resistance. Here for high-speed cutting tool material and performance and reasonable selection of measures to explore.
