Ti(CxN1-x)基金属陶瓷刀具材料的应用研发

Development and Application of Ti( CxN1-x) Based Cermet

硬质合金精密刀具中的可转位刀具、整体刀具、3C刀具和PCB微型刀具等,以优异的基体技术、磨削工艺和涂层技术为基础,以高效率、高速度、高精度和长寿命等特性,满足了飞机、汽车、造船、3C(计算机、通讯和电子消费品的统称)等高端制造业的需求。据统计,这些小小的刀具,全球的市场规模已达到100亿美元。本文介绍了Ti(CxN1-x)基金属陶瓷的资源优势、加工优势和性能优势,分析了Ti(CxN1-x)基金属陶瓷的技术瓶颈,重点评述了厦钨研发团队针对国内应用现状开发Ti(CxN1-x)基金属陶瓷刀具的国产化路线,并展望了Ti(CxN1-x)基金属陶瓷刀具的市场前景。目前,Ti(CxN1-x)基金属陶瓷材料在刀具材料中所占份额,在发达国家约为1/5~1/4,日本已达1/3,且使用量仍在逐年剧增,未来金属陶瓷可转位刀具的需求量将占其总量的50%。按此推算,未来10年,我国金属陶瓷刀具将形成50~60亿元的市场规模。

Cemented carbide precision tools are based on excellent matrix technology, grinding technology and coating technology. They have the characteristics of high efficiency, high speed, high precision, and long life. The product categories mainly include insert, end mill, and cutting tools for 3C (computer, communications, and electronic consumer goods) and PCB (printed circuit board) machining. Cemented carbide precision tools meet the needs of high-end manufacturing industries such as aircraft, automobiles, shipbuilding, and 3C. According to statistics, the global market for cutting tools has reached 10 billion US dollars. In this paper, the resource advantages, processing advantages and performance advantages of Ti(C x N 1- x )-based cermet are introduced, the technical limitations of Ti(C x N 1- x )-based cermet is analyzed, and the devel opment of Ti for the domestic application status of Xiamen Tungsten R&D is introduced. Based on the research on Ti(C x N 1- x ) based cermet tools, the future of the market is prospected. At present, Ti(C x N 1- x ) based cermets account for about 1/5 to 1/4 of the cutting tool materials in developed countries, and Japan has reached 1/3. The use of Ti(C x N 1- x ) based cermets is still increasing year by year. The demand for cermet indexable tools will account for 50% of the total in the future. According to this calculation, in the next 10 years, Chinese cermet cutting tools will form a market scale of 5 to 6 billion yuan.
