Description
Technical field
The invention belongs to removing material technical field, relate to a kind of based on grinding unit implant diamond 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 develops through over half a century, especially
After being reform and opening-up, in eighties of last century the nineties, China's removing material industry is with world-class
Gap was once substantially reduced.But, due to world's material science and technology, mechanical processing technique and modern times
The fast development of science and technology, external removing material industry development is rapid, new technique, new product, new work
Skill continues to bring out.And the removing material industry of China in this in period be in the system of industrial management change, enterprise
In the stage that industry changes direction, industrial organization structure adjusts, original industrial pattern is disturbed, new market
Order is being explored foundation, industry development and technological progress and is being stayed cool for the moment so that already
The gap reduced is widened rapidly again.
In recent ten years, removing material manufacturing enterprise of China achieves significant progress, has gradually formed product
Product A wide selection of colours and designs, there is the removing material production system of certain comprehensive strength.And then define with transnational public affairs
Department and co-partnership company and several domestic corporation are main high-end removing material manufacturing enterprise, with state-owned or
Large and medium-sized enterprise that state-run assets are holding and the big private developed rapidly in recent years and characteristic private enterprise are
Main middle and high end removing material manufacturing enterprise；And the low and middle-end removing material based on minor private enterprises
Three levels of manufacturing enterprise.Whole nation year removing material production capacity has had sizable scale at present, permissible
Say it is the big producing country of removing material.But not being the power of removing material, removing material top with the world is looked forward to
Industry is compared, the most certain gap.It is mainly manifested in (1) overall craft and equipment also has certain gap.
Removing material manufacturing enterprise of China has had very through development in recent years, the equipment of some leading enterprises
Big improving, some processes and equipment have reached first-class level of modernization in line with international standards, but totally
Technique and equipment also certain gap compared with international removing material advanced enterprises, particularly produces new
Product research and development, automatization and equipment application aspect.(2) there are mainly some skills of international competitiveness in the past
The product that art content is low, added value is less, and there is the high-tech product shortcoming of independent core technology.But
In recent years, though situation has change, but in the exploitation application progress of new type abrasive, function removing material
Slowly.(3) low in economic efficiency.The Industrial added value of removing material manufacturing enterprise of advanced country is substantially
Between 50% to 150%, minimum also more than 30%, removing material manufacturing enterprise of China but only has
5～20%, have a long way to go.(4) not enough, at Product Process, the height of removing material due to theory innovation
End properties of product and research and development of new product aspect, also have sizable gap (5) enterprise pair with Foreign Advanced Lerel
The quick-reaction capability in market is poor.China's removing material new product average construction cycle is 18 months, produces
The life cycle of product is 10～15 years.And abroad realize " three three ", i.e. the life cycle of product
Being 3 years, the trial-production cycle of product is 3 months, and the design cycle of product was 3 week.(6) enterprise
The structure of size is unreasonable.From the point of view of industrial organization structure, China's removing material manufacturing enterprise scale pole does not conforms to
Reason, large enterprise is strong greatly and not, and small business is little and special, and enterprise has been absorbed in deadlocked in the market competition
State.The particularly strength of large enterprise still can not realize appropriate scale of operation and collectivized operation, it is difficult to
Multinational corporations contends with.In general, though China's removing material industry achieves significant progress.But
Owing to product independent research and development capacity is weak, entry threshold is relatively low, and the nearly more than ten years are imitating always, plagiarize
On the basis of develop and expansion, inefficient consumes a large amount of valuable resource and the energy, first intakes with the world
Flat compare the biggest gap, be mainly manifested in: high-tech product can not meet the market demand, rely on into
Mouthful；There is structural surplus in the low-grade universal product, cause overstocked, be in arrears with payment for goods and price war.The whole industry
Production capacity has reached certain scale, but actual production capacity is relatively decentralized, and scope of the enterprise is little, economic effect
Benefit is poor.Technology development capability is weak, and product and the technology of own intellectual property are few, do not grasp product development
Initiative.Product variety is few, with low content of technology.Removing material industry domestic famous brand gold content is low, more
Rare international famous brand.
This technique of grinding the most at home and abroad develops very rapidly and is widely available application, along with the modern times
Developing rapidly of industry and being gradually improved of coated abrasive tool manufacturing technology, it is as a kind of unconventional grinding
Technology, with the processing characteristic of its uniqueness, impact car, milling, dig, traditional manufacturing technology such as mill.It was both
Can grinding metal (including difficult-to-machine metal), again can grinding be nonmetal (includes glass, leather, timber, treasured
Stone).From space flight and aviation industry, car industry to building materials industry, the table of floor furniture in life from light industry to people
Facing sand light, grinding technique is obtained for extensively application in all trades and professions.Americanized Engineering society (S, M, Z)
Think: grinding is that one is widely used, in high precision, high efficiency, the process technology of low cost, its working (machining) efficiency
Exceed car, milling, plane processing.

The industrially developed country such as beautiful and Japanese, is engaged in grinding technique research, the research institution of exploitation and manufacturing firm
(or group) quantity is a lot of and fully reinforced, and its achievement and product represent world today's grinding technique
Top level.
Domestic Grinding Technology is just to start to be able to true development in late 1970s, along with
Domestic reform and opening-up, Sand Band Grinding Technique causes every profession and trade, each research unit and each enterprise day by day
Pay attention to, in addition the development of the manufacturing technology of removing material and the increase of kind so that the research of equipment for grinding
Bigger development is have also been obtained with producing.Grinding just towards strength, at a high speed, efficient and high-precision direction develops.
Due to distinctive processing characteristics and the high material removing rate of grinding, grinding has been also introduced into domestic
Many new applications, solve many processing difficult problems.Grinding not only can realize traditional material
Processing and also can realize the big surplus precision rubbing down to the difficult-to-machine material such as rustless steel, titanium alloy processing,
Efficiency is high, good processing accuracy, and surface roughness is low, and abrasion is few, and service life is long, and processing cost is low.
Although domestic Grinding Technology is being caught up with rapidly, but with abroad compare from quantity the most also
It is that quality has bigger gap.In terms of high-speed grinding, the U.S. has succeeded in developing the high speed of 100m/s
Abrasive belt grinding machine.High efficient grinding aspect, Westinghouse Electrical Corp. centreless abrasive belt grinding machine 60 horsepowers of rotors of processing,
Per hour up to thousand；Concentricity requirement 0.005mm of Wu Lusen lathe company, error exist
The rotor of 0.012mm can reach 200 per hour, the every cm width of abrasive belt surface grinder of 3m company
650cm can be excised3/min。
Owing to the power utilization of grinding is high, material removing rate is high, and this external abrasive machine also has processing model
Enclosing wide, integrated cost is low, simple in construction, and small investment is simple to operate, produces non-cutting time few, work
The advantage such as safe and reliable, grinding application rapidly be development at home.Therefore, new abrasive material, new base are developed
Material, new binding agent and coating material improve the configuration of abrasive particle, improve the performance of removing material
And quality, improve the key issue that service life is removing material application.
