Description
Technical field
The invention belongs to removing material technical field, relate to a kind of diamond based on grinding unit implantation or CBN grinding tool preparation method.
Background technology
The removing material industry of China is grown out of nothing, and changes from small to big, and through over half a century development, particularly after reform and opening-up, in eighties of last century the nineties, China's removing material industry and world-class gap once reduced greatly.But due to the fast development of world's material science and technology, mechanical processing technique and modern science and technology, external removing material industry development is rapid, and new technology, new product, new technology continue to bring out.And this in period China removing material industry be in that the system of industrial management changes, enterprise changes direction, the stage of industrial organization structure adjustment, original industrial pattern is upset, new market order explores foundation, industry development and technological progress stay cool for the moment, and the gap already reduced is widened rapidly again.
In recent ten years, removing material manufacturing enterprise of China achieves significant progress, progressively defines the removing material production system that product category is complete, have certain comprehensive strength.And then the high-end removing material manufacturing enterprise defined based on trans-corporation and co-partnership company and several domestic corporation, the middle and high end removing material manufacturing enterprise of the large and medium-sized enterprise controlled interest based on state-owned or state-run assets and the big private developed rapidly in recent years and characteristic private enterprise; And low and middle-end removing material manufacturing enterprise three levels based on minor private enterprises.Current whole nation year removing material production capacity has had sizable scale, can be described as the big producing country of removing material.But not the power of removing material, compared with the top removing material enterprise in the world, also have certain gap.Be mainly manifested in (1) overall craft and equipment certain gap in addition.Removing material manufacturing enterprise of China is through development in recent years, the equipment of some leading enterprises has had large increase, some processes and equipment reach first-class modernization level in line with international standards, but overall craft and equipment also have certain gap compared with international removing material advanced enterprises, particularly in new-product development, automation and equipment application aspect.(2) there are mainly some with low content of technology, that added value is less products of international competitiveness in the past, and there is the high-tech product shortcoming of independent core technology.But in recent years, though situation has change, make slow progress in the Application and Development field of new type abrasive, function removing material.(3) low in economic efficiency.The Industrial added value of removing material manufacturing enterprise of advanced country is substantially between 50% to 150%, and minimum also more than 30%, removing material manufacturing enterprise of China but only has 5 ~ 20%, has a long way to go.(4) because theory innovation is not enough, in the Product Process of removing material, high-end product performance and research and development of new product, also have the quick-reaction capability of sizable gap (5) enterprise to market poor with Foreign Advanced Lerel.China's removing material new product average construction cycle is 18 months, and the life cycle of product is 10 ~ 15 years.And realize " three three " abroad, namely the life cycle of product is 3 years, and the trial-produce period of product is 3 months, and the design cycle of product was 3 week.(6) scale structure of enterprise is unreasonable.From industrial organization structure, removing material manufacturing enterprise of China scale is extremely unreasonable, and large enterprise is strong greatly and not, and small business is little and not specially, enterprise has been absorbed in deadlock in market competition.Particularly the strength of large enterprise still can not realize appropriate scale of operation and collectivized operation, is difficult to contend with trans-corporation.In general, though China's removing material industry achieves significant progress.But because product independent research and development capacity is weak, entry threshold is lower, development and expansion on the basis that the nearly more than ten years are imitating always, plagiarize, inefficient consumes a large amount of valuable resource and the energy, larger gap is also had compared with international most advanced level, be mainly manifested in: high-tech product can not be met the need of market, dependence on import; There is structural surplus in the low-grade universal product, cause overstocked, be in arrears with payment for goods and price war.Whole industry production capacity reaches certain scale, but actual production capacity is comparatively disperseed, and scope of the enterprise is little, deficiency in economic performance.Technology development capability is weak, and product and the technology of own intellectual property are few, do not grasp the initiative of product development.Product variety is few, with low content of technology.Removing material industry domestic famous brand gold content is low, rarer international famous brand.
This technique of grinding at home and abroad developed very rapidly in recent years and was extensively applied, along with developing rapidly of modern industry and being gradually improved of coated abrasive tool manufacturing technology, it is as the unconventional grinding technique of one, with the processing characteristic of its uniqueness, impact the manufacturing technology that car, milling, plane, mill etc. are traditional.It both can grinding metal (comprising difficult-to-machine metal), again can grinding nonmetal (comprising glass, leather, timber, jewel).From space flight and aviation industry, car industry is to building materials industry, and the sanding surface of floor furniture in living from light industry to people, grinding technique is obtained for extensive use in all trades and professions.Americanized Engineering society (S, M, Z) is thought: grinding is that one is widely used, high accuracy, high efficiency, the process technology of low cost, and its working (machining) efficiency exceedes car, milling, plane processing.
External Grinding Technology development is very fast, has now reached quite high level.Particularly Europe, the United States and Japan etc. industrially developed country, be engaged in grinding technique research, the research institution of exploitation and manufacturing firm (or group) quantity a lot of and fully reinforced, its achievement and product represent the highest level of world today's grinding technique.
Domestic Grinding Technology just starts to be able to true development in late 1970s, along with domestic reform and opening-up, Sand Band Grinding Technique causes the pay attention to day by day of every profession and trade, each research unit and each enterprise, in addition the development of the manufacturing technology of removing material and the increase of kind, makes the research of equipment for grinding and production have also been obtained larger development.Grinding just towards powerful, at a high speed, efficient and high-precision future development.Due to distinctive processing characteristics and the high material removing rate of grinding, grinding has also been introduced in domestic many new applications, solves many processing difficult problems.Grinding not only can realize the processing of traditional material but also can realize the accurate rubbing down processing of the large surplus of the difficult-to-machine material such as stainless steel, titanium alloy, and efficiency is high, good processing accuracy, and surface roughness is low, and wearing and tearing are few, and long service life, processing cost is low.
Although domestic Grinding Technology is being caught up with rapidly, all there iing larger gap with comparing from quantity or quality abroad.In high-speed grinding, the U.S. has succeeded in developing the high speed abrasive belt grinding machine of 100m/s.High efficient grinding aspect, Westinghouse Electrical Corp. centreless abrasive belt grinding machine processes 60 horsepowers of rotors, per hourly reaches thousand; Concentricity requirement 0.005mm, the error of Wu Lusen lathe company per hourly can reach 200 at the rotor of 0.012mm, and the every cm width of abrasive belt surface grinder of 3m company can excise 650cm
3/ min.
Because the power utilization of grinding is high, material removing rate is high, and it is wide that this external abrasive machine also has the range of work, and integrated cost is low, structure is simple, and small investment is simple to operate, it is few to produce non-cutting time, the advantage such as safe and reliable, and grinding is applied in and is domesticly developed rapidly.Therefore, develop new abrasive material, new base material, new binding agent and coating material to improve the structural form of abrasive particle, to improve the Performance and quality of removing material, improve the key issue that service life is removing material application.
