机夹刀具是目前国外普遍采用的技术经济效益显著的先进刀具。日前,美国、瑞典、西德等国机夹刀具的使用而已经达到90～95%,而且已经广泛地采用涂层硬质合金刀具,涂层硬质合金刀片的使用面已经达到60～70%。涂层刀片已经发展到第三代产品,即 Tic+Al_2O_3+TiN 三层涂层,瑞典山德维克公司第四代硬质合金涂层材料 GC415正成为广泛宣传的新型涂层材料。据美国 Kennametal 公司预测,硬质合金及其涂层材料在九十年代仍然是
The machine tool is a cutting-edge advanced tool that is widely used in foreign countries. Recently, the United States, Sweden, West Germany and other countries have reached 90 to 95% of the use of machine tools, and has been widely used coated carbide tools, coated carbide surface has reached 60 to 70% of the blade . Coated inserts have been developed into the third generation of products, namely Tic+Al_2O_3+TiN three-layer coating, and Sweden Sandvik’s fourth-generation cemented carbide coating material GC415 is becoming a new type of coating material widely publicized. According to U.S. Kennametal’s prediction, cemented carbide and its coating materials are still in the 1990s
