With the combination of tool technology and machine tool
technology, workpiece materials and tool materials to promote each
other, aerospace manufacturing industry continues to develop. It can be
said that the continuous development of tool materials is the driving
force for the continuous development of aerospace manufacturing. At
present, aerospace manufacturing industry widely used tooling grades up
to thousands of models, according to the tool material to divide,
nothing more than the following categories: tool steel (carbon tool
steel, alloy tool steel, high speed steel), carbide , Ceramic and
superhard tool material. Carbon tool steel is suitable for manufacturing
hand tools, carbon tool steel T10A and T12A applications are more
extensive.
In the aviation manufacturing industry, the proportion of carbide cutting tools is the largest. Carbide tool in the aviation manufacturing is the leading tool, the scope of application is quite wide, in the NC tool material dominated. Carbide has become the main tool material, so that the cutting process to achieve the transition to the carbide age, due to different grades of carbide characteristics of different characteristics, and therefore its scope of application is also different. Carbide can be used not only to manufacture a variety of machine can be translatable tool, and can create a whole type of end mills, reamers, taps and drill bits. Carbide tools are divided into ordinary hard alloy, coated carbide, ultrafine particles of cemented carbide, carbon (nitrogen) titanium-based cemented carbide.
YT-type cemented carbide with YG class and YW class most of the excellent performance in the aerospace manufacturing industry is more widely used. Coated carbide has a higher hardness than the matrix, wear resistance, heat resistance, widely used. Ultrafine particles Carbide can be used in a wide range of intermittent cutting. Carbon (nitrogen) titanium-based cemented carbide is mainly used for the continuous surface finishing and semi-finishing of steel parts.
At present, China's ceramic tool application is still in its infancy, the actual application of the development of slower. Ceramic cutting tools are mainly used for hard alloy cutting tools(or carbide tools) difficult to cut the workpiece roughing. Aerospace manufacturing industry to promote the use of ceramic tools for a long time, in the ceramic tool geometric parameters, cutting the amount of use and technology need to accumulate experience. Ceramic materials Compared with cemented carbide, ceramic materials have higher hardness, thermal and abrasion resistance. Ceramic tool chemical stability, antioxidant capacity are better than carbide, very suitable for dry continuous high-speed cutting high-temperature alloys, hardened just, bearing steel, high strength steel and other difficult to process materials. Aero engines in the application of many high-temperature alloys, shaft parts more, it is the ceramic tool to play its advantages. To achieve efficient processing, to replace some of the ceramic cutting tool carbide tool is completely feasible. Ceramic tool is not a universal tool, only the correct use in order to give full play to its superiority.
