The development direction of carbide cutting tool materials and application at present.

The development direction of cutting tool materials and application at present, in the field of aircraft manufacturing, high speed steel cutting tools account for about 60% of the total amount of all kinds of cutting tool always, carbide cutting tools account for about 35% of the total amount of cutting tool, superhard cutting tools (cubic boron nitride, diamond) accounted for less than 5% total all the cutting tool and the future with the airline new materials constantly emerging, the increase of hard cutting, dry cutting application, carbide cutting tools, coated tools, ceramic cutting tool, cubic boron nitride cutting tool and the proportion of polycrystalline diamond cutting tools will be greatly increased.

1 the development of cemented carbide materials in order to meet the rapid development of high speed cutting technology, various is given priority to with cemented carbide cutting tool material performance has been improving, fine particles, and the development of ultra-fine grain cemented carbide and coating technology in the application of carbide cutting tools pronouncedly improved strength and toughness of cemented carbide material, use it to make the overall alloy cutting tool is gradually replaced traditional HSS cutting tools, to improve cutting speed and processing efficiency by several times, laid the important foundation for the application of high speed cutting. Solid carbide also have been applied in some complicated forming cutter and meet the demand of the diversity of product processing. At present domestic gesac measures are useful in xiam special alloy co., LTD., zhuzhou diamond hard cutting tool co., LTD., siping usain bolt process equipment co., LTD., and shaanxi aeronautic carbide tool company can offer carbide cutting tools for the airline industry, its product performance is close to the world's advanced level. Carbide cutting tool materials in the 21st century should focus on development in two aspects: one is fine grains to nanoscale microcrystalline level. Carbide grain size is smaller, the higher the hardness of cemented carbide its wear resistance is better, the higher the toughness and stiffness, so as to expand the scope of its application; The second is using new technology and new technology development of new carbide carbide inner performance and quality.
