According to information in Osaka, Japan Oura Gui Diamond Industrial Company provided a president, world consumption of superhard abrasive tools market has reached $ 3.3 billion, of which the amount of stone and construction industry accounts for nearly half, to 49.4%; abrasive category accounted for 30%; composite polycrystalline tools accounted for 18.2%. Abrasives this species, CBN abrasive abrasive accounted for 28% of the total. Compared with the world market, it is clear there is division ratio of the domestic market with a big difference, one: tools of stone and construction industry as high as 70% to 80%, far higher than the international market share; Second: Abrasives, CBN low abrasive ratio. The reason, one of the high proportion of high-grade diamond because too few, so many stone tools only with low-grade diamond substitute, saw blades and other tools resulting in low life; or to reach a certain tool life, increased diamond concentration , so it is not particularly developed for the construction of stone. Second, because of our machining cast iron, steel and other selected abrasive still common abrasive, CBN abrasive usage is very limited, at most, can only be regarded as the initial stage. So this one has great potential for development.
What superhard material products coming years new product development direction? Serious research should be conducted on the following aspects, the use of information from abroad, find out the domestic market demand, develop a realistic development plan.
Automotive industry (including some other power machinery, etc.)
For a long period of time, the auto industry would have been obtained as a pillar industry of the national economy than the high-speed development. Automotive development process depends on the level of car equipment levels improved, especially appropriate processing CNC machine tools (including cutting tools, abrasives) advanced degree. Efforts to develop advanced automotive components essential for superhard materials processing tool, abrasive, abrasives industry is the automotive industry to adapt to the need to promote their own development.
China's automobile industry status quo, drawing on the experience of developed countries mature, we should mainly develop: processing piston ring with CBN disc; precision machining with high abrasion CBN wheel bearings (including ceramic binder resin); PCBN machining of cast iron parts abrasive tools, honing tools; various hydraulic parts machining holes grinding; car windows, car mirrors and other glass processing with a variety of diamond grinding wheel, set the drill; plastics, rubber, other non-metallic materials processing with diamond grinding wheel; CPD aluminum alloy processing tool; various uses of diamond dressing roller and so on.
Brittle non-metallic materials processing
This range is very wide, put the emphasis should still closely related infrastructure on the building materials industry, road transport facilities and other industries. Separate the material is concerned, the focus can be put on the wearable tiles, glass, ceramics and other processing.
Wear-resistant tiles domestic industry in recent years has introduced more than 100 advanced production lines (mainly from Italy, Germany, Japan), the supporting plate grinding roller, grinding, milling chamfer grinding wheel are required localization. This is a broad market prospects, the difficulty is relatively large, according to the statistics, only coastal province hundreds of brick manufacturing enterprises, 97-year import processing tiles wheel over one hundred million yuan. The national production companies thousands of tiles, ceramic tile production in 1995 reached 90 million, the development trend of the industry gradually replaced by a wear-resistant glazed tiles, floor tiles and therefore greater and greater processing capacity, the industry come in handy place. Although there are many diamond products factory has developed processing tiles wheel, but are not mature enough in recent years Glass industry should focus on the various uses of flat glass processing, because it large wide, flat glass key breakthrough leveling, grinding forward, down the slope, grinding, polishing and other processes arc with a diamond wheel, imported automatic production line to achieve processing efficiency requirements , precision grinding wheel life, you need to put people in the industry with great enthusiasm, human capital can only make a difference. Lighting glass processing have great development in recent years, the industry is uneven, both very advanced automated processing equipment, there are also hand-grinding equipment is relatively backward, lamps to be processed glass pieces ranging from a few to as many as ten thousand or even more than one hundred thousand parts, and therefore should focus on market needs, the development of different purposes, different quality levels, the price of different grades of diamond processing tools.
Ceramic materials developed rapidly, mainly as life from the past to the development of industrial timber timber, tools and materials engineering materials. Ceramic materials processing inseparable diamond. Although China has just started precision ceramic applications, in accordance with the development trend of the 21st century will get a wide range of applications, an important member of the new materials industry. So you want to live ceramics, electronic ceramics processing experience, based on the efforts to develop new diamond processing tools, precision ceramic processing problems to solve.
Wood products and plastics processing
Wood processing and furniture has been extensive use of automated tools to replace the traditional manual operation mode, in addition to the use of materials such as wood processing generate waste sawdust, shavings, short timber and forestry resources trim down some branches, hardwood, then add the crushed plastic processing binder, and then by a series of treatment, made "recycled materials", the difficulty of processing this material harder than wood. Thus gave rise to the two requirements: First, the automated processing of wood and plastic products requires the use of many types of carbide or high speed steel cutting tools. Because of wood, plastic, etc. poor thermal conductivity, high-speed machining and cutting tools easily blunt or deformed, thus cutting tool replacement or grinding become frequent, produced exclusively for this purpose woodworking cutting tools for plastic diamond CBN wheel series. Grinding and cutting tools for the woodworking there are 97 kinds of diamond grinding gauge shape 173 specifications (including size, particle size), processing of plastic products and cutting tools wheel has 20 kinds of shape 28 specifications. Domestic wood and plastic industry has a lot of advanced production lines imported or imitation, tool manufacturing plant has made a lot of wheel orders intentions. Second, woodworking, plastic industrial complex polycrystalline diamond or CBN tools have also been put on the agenda, especially the wooden floor of the machining PCD cutting tools, the country has a considerable amount of (mainly in Yunnan, Sichuan and the Northeast and other places), so developers PCD tools for forest products processing is imperative.
Dressing tool development
Dressing tool in the industry belong to a shortage of basic goods, the early formation of industry-scale production, there are several plants producing diamond dressing pen products, in addition to individual units of the current production trim wheel, almost empty the rest of the dressing tool industry. Open foreign product samples, you can see almost all of the super-hard material products companies are producing diamond dressing tools. In winter's case, the company produces a single-point multi-point two categories dressing tool, its multi-point has Fliese, Igel, pro-dress, Rondist four varieties count 17 kinds of models. Single point there Single-point, one-way, profile three varieties count 23 kinds of models. To apply to various uses, various methods of grinding, grinding machines including plastic abrasive trimming purposes. Why not form a domestic dressing tools product line in the industry, may have a great relationship with our untapped natural diamond products, in addition to the low level of domestic grinder automation is also one of the reasons that many users have their own purchasing large grain diamond brazed welded into dressing tool (single grain), it may not be for the average grinder problem, and certainly not for the automated processing equipment. When making the choice of diamond dressing tools, depending on the application, you can use natural diamond, synthetic single crystal or polycrystalline diamond, polycrystalline diamond composite even so entirely conditional use within the industry.
Application and development of various polycrystalline products
According to 1994 data show that GE companies, 1993 World superhard abrasive products market PCD, PCBN cutting tools, PCD drawing dies, PCD mining drilling tools annual consumption reached 603 million U.S. dollars, accounting for 18.2% of the products consumed enough explain the market capacity and broad development prospects. In recent years, domestic PCD, PCBN products has made great progress, but still a very small market share, mainly due to: a single species, it is difficult to adapt to changing market demands; domestic equipment can not adapt to the use of such tools; supply and demand sides lack of communication and cooperation, understanding level hysteresis; polycrystalline composite tooling, special grinding there are still some problems.
Composite polycrystalline tool development can take the "easy things first," the road, for example, to develop a variety of materials processing PCD / PCBN turning, since turning shape is relatively simple, but made lathes (including ordinary lathe CNC lathe) basic fit use PCD / PCBN Cutters, mainly to cast iron, hardened steel, aluminum, carbon fiber and other materials, machining difficult, processing effect is significant, so it is easy for the user to accept. Mining and oil and gas into the drilling tools, PCD requires a high quality, is also a great tool for making difficult, high technology content, the price level is also high, is a high-tech product, so to work hard PCD manufacturing quality level, once the quality breakthrough, you can put tools developed.
20th Century superhard abrasives industry from scratch, from small to big, has made remarkable achievements for the country's economic development and technological progress contributed. In the 21st century we should strengthen our confidence, seize opportunities, grasp the direction, struggling to develop, so that the industry grow stronger, so that our country really become super abrasive products manufacturing exporter, create brilliant achievements for the world economic development and technological progress.
