Superhard tools present situation and market development trend
Date：2021-06-09Number：1719
Superhard tools are playing an increasingly important role in modern processing industry, and improving the hardness, toughness and stability of superhard tool materials has always been the common pursuit of science and industry.
China's superhard tools are widely used in geological exploration, stone, machinery, automotive and national defense industry and other fields, machining with abrasive tools, geological drill and stone saw cutting tools manufacturing technology level has been greatly improved, products have formed a series, standardization, complete specifications, product quality is stable, some products in the international market has a certain competitiveness. Various superhard tools are also widely used in various industries and have achieved significant economic benefits, but as far as the entire superhard tool industry is concerned, it is still necessary to improve industrial planning, broaden the application field, and create international brands.
Diamond hardness and wear resistance is very high, the cutting edge is very sharp, the edge roughness value is small, the friction factor is low, the adhesion resistance is good, the thermal conductivity is high, the cutting is not easy to stick the knife and produce chip nodules, the processing surface quality is good. When processing non-ferrous metals, the surface roughness value can reach R0.10 ~ 0.05m, and the processing accuracy can reach IT5(hole IT6) level or above, which can effectively process non-ferrous metal materials and non-metallic materials. Such as copper, aluminum and other non-ferrous metals and their alloys, ceramics, unsintered cemented carbide, various fiber and particle reinforced composite materials, plastics, rubber, graphite, glass and various wear-resistant wood (especially solid wood and plywood, MDF and other composite materials).
1. Early development
Due to blind development, hardware tools, especially super hard tools production layout appears scattered and chaotic, everywhere flowering situation, production enterprise scale is generally small, production is not concentrated, poor process technology, lack of market competitiveness, tool sales market product quality is unstable, competition disorder, price chaos, economic efficiency is not high.
2. Current Situation
At present, the domestic tool production and new product development, process technology research and other aspects of insufficient investment, to increase the investment in the tool industry, pay close attention to the development of new products and new technology, new process promotion, and constantly expand the diamond application field, improve the overall technical level and market competitiveness of the superhard tool industry, to survive by variety, quality, and scientific and technological progress for development.
In order to meet the needs of domestic and foreign tool markets, it is necessary to speed up the development of new products, improve product quality, increase varieties and increase output. In recent years, machinery, gems, medical equipment, wood, glass fiber reinforced plastic, stone crafts, ceramics and composite non-metallic hard and brittle materials processing field demand for superhard tools increased year by year, at present, these products are still dependent on imports, so we must develop a variety of high-quality tools as soon as possible to replace imports.
At present, the products that need to be developed are: diamond tools, PCD diamond tools, super hard tools, super hard tools, diamond tools, diamond tools, CBN cubic boron nitride tools, CBN cubic boron nitride blades, PCD diamond blades, diamond blades, etc.
3. Development
The enterprise should constantly innovate advanced process technology, constantly improve the production process, reduce production costs, and improve economic benefits. Take the road of collectivization or joint enterprise, set up several large enterprise groups, guide the development of the industry, create their own brands, and actively participate in international competition. Relying on scientific and technological progress, increase scientific and technological investment, update equipment, pay close attention to the research and promotion of new technologies, new processes and new products, improve the utilization rate of tool base materials, accelerate the development of China's hardware tool industry, and further improve economic benefits and the overall technical level.
