With modern science and technology and the development of production, a variety of new materials difficult to machine large number of applications in the product, the traditional carbide tools have concrete core bits been difficult to meet production needs, while the ceramic tool is its excellent heat resistance, wear , good chemical stability and high cost and by people of all ages. Especially in the field of high-speed cutting and difficult to machine materials, showing the traditional tools can not match advantage.
The use of ceramic cutting tools ordinary steel, cast iron, hardened steel, high manganese steel, nickel-based superalloy, powder PCD grinding wheel metallurgy sintered parts, glass, steel and a variety of engineering plastics and other difficult to machine materials, tool life and even several times higher than the carbide tools ten times. It can not only in production for general turning, boring and milling, and has been successfully used on the hole processing tool; except in the ordinary use of the machine, but also can be effectively used CNC machine tools and machining centers, high- equipment, is internationally recognized as the most contemporary improve production efficiency as a potential tool. In addition, diamond and cubic boron nitride and other superhard cutting tool compared to the relatively low concrete ring saw price of ceramic cutting tools (ceramic cutting the main raw material of aluminum oxide, silicon is the most abundant element in the crust, inexhaustible, with inexhaustible), therefore, it was said: "With modern ceramic tool material properties of continuous improvement, in the future it will work with coated carbide cutting tools, diamond and cubic boron nitride and other superhard cutting tool with a high-speed cutting, dry cutting and The three main hard cutting tool. "Figure 1 shows the tool in hard turning using ceramic instead of grinding the carburized hardened gear (57 HRC-59 HRC) synchronization cone part, bore and back The application examples.
Diamond tool is mainly used for a variety of non-ferrous metals such as aluminum turning, copper, magnesium and its alloys, tungsten carbide and wear strong fiber reinforced plastic materials, metal matrix composites, wood and other non-metallic materials. When cutting speed, feed rate and depth of cut depends on processing conditions and the hardness of the workpiece material.
