Explore use of new superhard materials
According to Osaka Diamond Industries Oura Keiichi president of information provided by the market, the world's super-hard abrasive tool consumption reached 3.3 billion U.S. dollars, of which nearly stone and construction industry accounts for about half the amount, to 49.4%; abrasive class accounted for about 30%; composite polycrystalline tools accounted for 18.2%. Abrasives this species, CBN abrasive grinding total volume of 28%. Compared with the world market is clearly divided into the proportion of the domestic market with a big difference, one of: stone and construction tools as high as 70% China 80%, much higher than the international market ratio; Secondly: abrasive, CBN the proportion of low abrasive. The reason for the high proportion of one of our high-grade diamond because too few, so many stone tools can only be used, low-grade diamond substitute, resulting in low life the saw blade and other tools; or to reach a certain tool life, increase the concentration of diamond and hence are not particularly well-developed construction industry of China's stone it. Second, because our processing of cast iron, steel, etc. are still common use abrasive abrasive, CBN abrasive usage is very limited, at best can only be regarded as an initial stage. So this one has great potential for development. ?
Superhard materials coming years new product development orientation? Should conduct serious research on the following reference to foreign use of information, find out the domestic market demand, to develop realistic development plans.
Automotive industry (including other power machinery, etc.)
For quite a long time, the automotive industry will remain as a pillar industry of national economy and achieve more rapid development. Development of automobile industry depends on the level of vehicle and equipment to improve the level of processing, especially in CNC machining of the appropriate tools (including cutting tools, grinding tools) advanced degree. Essential to the development of advanced automotive components machining hard material tools, grinding tools, abrasives industry is to meet the auto industry to promote their own development needs.
Status for China's automobile industry, learn from the experiences of developed countries, we should be the main development: use of CBN grinding disc machining piston rings; high-precision processing of high wear resistant CBN wheel bearings (including ceramic binder resins); all kinds of cast iron parts processing PCBN cutter grinding, honing tool; a variety of hydraulic components for processing small hole grinding; car windows, car mirrors and other glass processing all kinds of diamond grinding wheel, set of drill; plastic, rubber, other non-metallic materials processing with diamond wheel; aluminum alloy processing CPD tool; various uses of diamond dressing roller and so on.
Hard and brittle non-metallic materials processing
The very wide scope, emphasis should be placed with the infrastructure remains closely related to building materials industry, road transport facilities and so on. Separate the material terms of the focus can be placed resistant tiles, glass, ceramics and processing.
Wear-resistant tile industry in recent years, China introduced more than 100 advanced production lines (mainly from Italy, Germany, Japan), the supporting plate flat roller, wheel, grinding wheels and chamfering wheels are subject to localization. This is a broad market prospects, and relatively more difficult, according to statistics, the only coastal province hundreds of tiles manufacturer, 97 years of import processing over 100 million yuan tile wheel. National production companies thousands of tiles, 95 tiles production reached 90 million years, the industry trend for the wear-resistant tiles glazed tiles gradually replaced by brick therefore increasing processing capacity, the industry has great development potentials of the Department. In recent years, many diamond products processing plant developed tile wheel, but are not mature enough. The glass industry should focus on the processing of flat glass for various purposes, as it out widely, focusing on leveling plate glass breaking, grinding forward, down slope, grinding process arc diamond polishing wheel, automatic production line imported to meet the provisions of processing efficiency precision grinding wheel life, need to trade into a great passion, human capital can only make a difference. Lighting glass processing in recent years a great development, the industry has been uneven, both very advanced automated processing equipment, there are relatively backward hand-grinding equipment, lighting need as little as a few pieces of processed glass, and even more than the last 10 000 more than 100,000 pieces, so should the market needs, develop different uses, different quality levels, prices varying grades of diamond processing tool. ?
Ceramic materials has developed rapidly, mainly as life from the past to the development of industrial timber materials, tools, materials engineering materials. Diamond ceramic materials processing can not be separated. Although the application of fine ceramics in China has just started, in accordance with the development trend of the 21st century will be widely used, an important member of the new materials industry. Therefore, in living ceramics, electronic ceramics based on the experience, efforts to develop new diamond processing tools for precision ceramic processing problems to solve.
Wood products and plastic products
Wood processing and furniture has been extensive use of automation tools replace the traditional manual process, in addition to use of wood waste materials generated as sawdust, shavings, short wood, and forestry resources, cutting down the number of branches, trees and foliage, then add plastic by grinding process type binder, and then by a series of treatment, made "recycled material", the difficulty of processing this material more difficult than the logs. Thus gave rise to two major needs: First, the automated processing of wood and plastic products need to adopt various types of carbide or high speed steel cutting tools. Because wood, plastic and other poor thermal conductivity, high-speed machining and cutting tools under extremely blunt or deformation, so the replacement or grinding and cutting tools have become frequent, produced exclusively for this purpose woodworking series plastic cutting tools diamond CBN grinding wheel. For wood cutting tools diamond grinding wheels include 97 kinds of shapes 173 specifications (including size, size), processing plastic cutlery grinding wheel shapes 28 and 20 specifications. Domestic wood and plastics industries have a lot of imported or imitation of advanced production lines, tools, grinding wheel manufacturing plant has made a lot of orders intention. Second, for the woodworking, plastics composite polycrystalline diamond or CBN tools have also been put on the agenda, in particular wooden floor planks processing PCD cutting tools, has been a considerable amount of domestic (mainly in Yunnan, Sichuan and northeast, etc.), so developers PCD tools for processing of forest products is imperative. ?
Dressing tool development
Dressing tools in the industry basically is a shortage of products, industry production of the initial scale, there are several factories producing diamond dressing document of the products, the current production of dressing roller than individual units, the remaining dressing tools in the industry is almost blank. Turn over samples of foreign products, you can see that almost all companies are producing superhard materials diamond dressing tools. To winter's case, the company produces single-point multi-point two categories dressing tools, its multi-point has Fliese, Igel, pro-dress, Rondist total of 17 models in four varieties. Single point with Single-point, one-way, profile of three species in 23 models. Applicable to various uses, a variety of grinding, including the grinding wheel grinding machine used plastic trim. Why dressing tool of domestic products in the industry, not form, may be we have not developed a great relationship with the natural diamond products, in addition to the low level of domestic grinding machine automation is also one reason why many users buy their own diamond with a large grain of copper welding into dressing tools (single grain), which may not be a problem for general grinding, but certainly not work for the automated processing equipment. Make use of diamond dressing tools, in accordance with different purposes, you can use natural diamond, synthetic single crystal or polycrystalline diamond, polycrystalline diamond composite or even, so the industry is perfectly placed to use.
Polycrystalline products of various application development
According to 1994 statistics provided by GE in 1993, the world's super-hard abrasive products market, PCD, PCBN cutting tools, PCD wire drawing die, PCD drilling tools mine annual consumption reached 603 million U.S. dollars, accounting for 18.2% of the entire product consumption, enough to on its huge market and broad development prospects. In recent years, domestic PCD, PCBN products has made great progress, but also a very small market share, mainly: a single species, it is difficult to adapt to changing market demand; made equipment can not adapt to the use of such tools; supply and demand both a lack of communication and cooperation, understanding Lag; composite PCD tool machining, especially grinding there is still a problem. ?
Composite polycrystalline tool development can go, "the easier" way, for example, the first development of a variety of materials processing PCD / PCBN turning tools, lathe tool shape for a more simple, homemade lathe (including ordinary lathe CNC lathe) Basic fit using PCD / PCBN turning tools, the process mainly cast iron, hardened steel, aluminum, carbon fiber and other materials, processing is not difficult, process is very effective, it is easy for the user to accept. Mining and oil and gas into the drilling tools, PCD has a high quality requirements, is also a great tool to make difficult, high technology, high price level, is a high-tech products, and therefore the level of manufacturing quality PCD efforts, once the quality The breakthrough can be developed into tools. ?
20th Century super-hard abrasives industry from scratch, from small to big, and scored remarkable achievements and progress of China's economy has contributed to the development of technology. The 21st century we should strengthen confidence, seize opportunities, grasp the direction, struggling to develop, so the industry from big to strong, so that Abrasive products in China really become a major exporter of production, scientific and technological progress for the world economic development and create brilliant achievements.
