做为刀具材料的硬质合金广泛地应用于金属加工中。用硬质合金刀具切削下来的切屑占整个切屑量的70%。但在目前的金属加工中,不仅出现了特殊性质的难加工材料,而且数控机床、多用机床和柔性生产系统等越来越普及,这就对硬质合金刀具的使用性能和可靠性提出了更高的要求。这不仅迫切 Carbide used as a tool material is widely used in metal processing. The chips cut with cemented carbide tools account for 70% of the total chip volume. However, in the current metal processing, not only difficult materials with special properties have emerged, but also CNC machine tools, multi-purpose machine tools and flexible production systems have become more and more popular, which makes the performance and reliability of carbide cutting tools more High demand. This is not only urgent
