Appear background ceramic tool 2 when using alloy tool steel, cutting tools up to about 8 m / min, while the use of high-speed steel, and more than double, when using carbide inferior to improve high-speed steel two times, cutting the workpiece surface quality and dimensional accuracy has greatly improved. Since the high-speed steel and carbide are expensive, tool welding and mechanical clamping occurs structure. From 1949 to 1950, the United States began using the tools, indexable inserts, soon used in milling and other tool. In 1938, the German company Degussa obtain patents on ceramic tool. In 1972, the ceramic knife how, American General Electric Company produced a polycrystalline synthetic diamond and PCBN inserts. These non-metallic tool material allows a higher speed cutting tool. In 1969, the ceramic knife wholesalers, Swedish Sandvik steel made by chemical vapor deposition method, the production of titanium carbide coated carbide inserts patent. In 1972, the United States and 拉古兰 邦沙 developed physical vapor deposition method, carbide or high speed steel tool surface coating of titanium carbide or titanium nitride hard layer. Surface coating method of the base material of high strength and toughness, and high surface hardness and wear resistance combine to make this composite material has better cutting performance.
