近代刀具材料从碳素工具钢、高速钢发展到今日的硬质合金、陶瓷刀具和超硬材料,使切削速度从每分钟几m跃至km水平。随着切削加工业的快速发展,高强度高硬度难切削材料与日俱增,对刀具的要求越来越严格。事实表明,现代工具行业远不适应切削加工业的需要,一个落后的工具制造业不可能支持一个先进的工业体系,并会给国民经济造成很大的损失。要实现高效合理地切削,必须有与之相适应的刀具材料,在影响金属切削发展的诸因素中,刀具材料起着决定的作用。刀具质量的优劣,将直接影响机械工业及相关行业的生存和发展。 Modern tool materials from carbon tool steel, high-speed steel to the development of today’s cemented carbide, ceramic tools and superhard materials, the cutting speed from several m to jpm level. With the rapid development of the cutting and processing industry, high-strength and high-hardness hard-cutting materials are increasing day by day, and the requirements for cutting tools are becoming more and more stringent. Facts show that the modern tool industry is far from meeting the needs of the cutting and processing industry. A backward tool manufacturing industry can not support an advanced industrial system and will cause great losses to the national economy. To achieve efficient and reasonable cutting, there must be appropriate tool material, the impact of the development of metal cutting tools, the material plays a decisive role. The pros and cons of tool quality, will directly affect the survival and development of the machinery industry and related industries.
