In recent years, China's machine tool industry has developed rapidly, and has achieved fruitful results, and has been in the position of the world's largest machine tool consumer country, production and importer for many years. However, the matching tool industry is not satisfactory, forming the awkward situation that domestic CNC machine tools do not match domestic cutting tools, and have to match the "foreign knife". The extensive development of China's cutting tool industry has exposed its defects in the period of economic restructuring and upgrading of products, which seriously restricted the healthy and orderly development of machine tool industry.  

With the progress of science and technology, the new application of new materials and the emergence of high-precision mechanical equipment, higher requirements for the performance of cutters have been put forward. The traditional high-speed steel cutters slowly retreat to the second line and are replaced by cemented carbide tools. Cemented carbide has a series of excellent properties, such as high hardness, wear-resistance, good strength, good toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance. It remains basically constant at 500 C, and has a very high hardness at 1000 C. Cemented carbide is widely used as cutting tool materials, such as turning tools, milling cutters, planing knives, drill bits, boring knives, etc., for cutting iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel. It can also be used for cutting refractory steel, stainless steel, high manganese steel, tool steel and other difficult to process materials. The cutting speed of new carbide tools is equivalent to hundreds of times of ordinary high-speed steel cutting tools. From the point of view of machining efficiency and product accuracy, cemented carbide tools are more suitable for future mechanical processing needs.

High grade cutting tools rely on imports, and the middle and low grade cutting tools have serious excess capacity. This is the embarrassing situation faced by China's cutting tool industry. Domestic cutting tools are not only far from the structure of foreign cutting tool products, nor can they satisfy the growing demand of domestic manufacturing and carbide tools. The problem of disjointed supply and demand structure is very serious. The consequence is that a large number of high-speed steel cutting tools are exported at low price, while high efficiency carbide tools have to rely on large quantities of imports. Proportionate, the structure is seriously unbalanced.

Today, with the globalization of market economy, it is particularly important to strive to narrow the gap between the international advanced level and to identify the trend of cutting tool industry and catch up with it. No matter from the survival space of the cutting tool industry in China, or from the overall situation of improving the competitiveness of the entire manufacturing industry, speeding up the structural adjustment and promoting the development of high efficiency carbide tools is imperative.
