切削工具材料作为向高速切削进军的主要材料正在不断发展着,这种情况即使在今后也不会改变。目前已可看到,随着数控机床和各种专用机床的引进,作为切削加工自动化、节省能源的工具、工具材料的可靠性成了应该具备的重要条件。切削工具的特点是要求耐磨性和耐用性;一般说可靠性时、多指耐用性。要适应这样的要求,必须采用既不损害耐磨性能又能增加韧性的通用性高的工具材料。工具材料的最近进
Cutting tool materials as the main material to enter the high-speed cutting is constantly evolving, this situation will not change in the future. Now we can see that with the introduction of CNC machine tools and various special machine tools, the reliability of tool materials has become an important condition that should be possessed as a tool for cutting automation and energy saving. Cutting tools are characterized by the requirements of wear resistance and durability; generally speaking, reliability, multi-finger durability. To meet such a requirement, it is necessary to adopt a highly versatile tool material that does not impair the wear resistance but also increases the toughness. The most recent tool material
