Industry dialysis: Tool innovation and industry restructuring

In recent 10 years, China's tool industry continued rapid growth, experienced in the winter of 2009 and the spring of 2010 the baptism of the financial storm, although the collapse of many small businesses, increased many new partners, but still with a strong momentum of rapid development, now is joy is sorrow, the personage inside course of study. Behind the rapid development, the enterprise also realize soberly, domestic tool industry high growth rates in the gold content is not high, a significant proportion of those companies at the expense of the environment, on the basis of cheap labor, produce inferior product to obtain huge profits. Twist drill, taper shank drill, tap, saw blade milling cutter, such as low end the market a scuffle, and slow growth in high-end products, automotive industry, mould industry, aerospace and other industries of high, refined, sharp complex cutting tool most dependent on imports.

At present, the metal cutting tool has started from high speed steel cutter to the development and production of carbide cutting tools, but strength is not enough, still in the majority with low. As a result, the transition to a high-end products as a very important task to grasp is imperative, especially slowing economic growth in the United States, the European market is sluggish, low-grade tools export is blocked, from the standpoint of energy and raw materials, a large number of export cheap tool has been misplaced. From the China machine tool industry association statistics show that China consumes 40% of the world's tool materials, sales revenue only accounts for 12% ~ 15% of the world tools, this shows that do not conform to the state of resource saving the concept of scientific development is put forward. To this end, during the period of "twelfth five-year" tool industry development in our country will present the following trend:

(1) rapid development momentum unstoppable, despite the macroeconomic regulation and control, but it is still in the stage of sustainable development.

(2) "speed, accuracy, efficiency, environmental protection" has become the industry consensus.

(3) the highlighting, competition is fierce. The restructuring and reorganization of state-owned enterprises, foreign companies, private companies rise, evolution

Aiming at the severe situation, domestic tool industry should pay, take the market as the guidance, actively adjust the industrial structure, improve product class, to develop automobiles, high-speed rail, home appliance, etc. New tool about the livelihood of the people. Look around in recent years, the popular industry, machinery, mould, energy and other cutting tools in China market prospect is very broad. Nowadays China has become the world's superpower machinery manufacturing, the tool market in the future in China, occupy the Chinese market is occupied the international market.

Change idea Speed up the development of

Cutting concept transformation includes two aspects: thought idea and production management idea.

(1) the concept of thinking Where is the efficient way to reduce costs? Nearly 20 years of cutting speed increased 5 ~ 10 times, but the processing efficiency increased by 50% ~ 100% only, the original? Because of them is the effect of cutting efficiency was occupied by a large number of the cutting time. Cutting machine in our country has developed rapidly in recent years, the ownership is ahead in the world, rank first, but it lags behind the cutting tool industry. If the common saying say good horse matchs good saddle, advanced machine tool does not match the advanced tool, the efficient machining efficiency is not play, will seriously affect the production efficiency, manufacturing to modern development.

Heavy host light tool concept has been deeply rooted in many people's mind, cutting technology and cutter industry, a big factor is the enterprise to stay in the old traditional concept on the use of cutting tool, which is cheap tool to control costs, rather than use efficient tool by improving the processing efficiency to achieve the goal of cost reduction. If CNC machine tools, machining center and other advanced cutting machine, with corresponding efficient cutting tools, knives, fake and inferior products, there is no market, China's processing industry will be a big step forward.

Modern machining tool cost is only 3% ~ 4% of the cost of manufacturing, but it had an enormous influence upon the total cost, machining efficiency increased by 20%, which is 15% lower manufacturing cost; Although use cheap tool prices fell by 20%, but the processing cost was only 0.5% decline; The knives' service life extension 1 times, processing cost can only reduce 1.5%. So more and more people have realized that increased investment in cutting tools for high speed machining, is to improve the efficiency, reduce cost, the most effective means of this is the idea of cutting a leap in recent years, I hope this idea become the conscious action of the enterprise.

(2) the production and business operation concept Conformism of conservative ideas in the development of our country's modern and efficient tool harm caused by far more than the influence of the technology behind. From the traditional standard tool development to modern efficient cutting tool, cutting tool industry in China?? Through a thoroughly remould oneself and change process full of difficulties and hardships. The process of the change caused some enterprise back, not grasped the nettle, but standing still, even decline. This should recognize the change is the need of The Times, the same is to go back or death. Manufacturing industry of our country is developing at an astonishing speed fast, only in automobile manufacturing, for example: from 1956 to 1992, spent 36 years, to 1 million vehicles, but only spent 4 years from 1992 to 1996 was producing 1.5 million vehicles, but also into geometric series later development of the situation, has more than 10 million vehicles in 2008, China became a global car production country, car is the leading industry, the rapid development of it, driving the development of related industries passive synchronization. A large modern manufacturing system, have been springing up in China, so, no matter from the tool industry in our country's own living space, or from the global need to see our country entire manufacturing competitiveness, enterprises to accelerate structural adjustment, promote the development of efficient tools are imperative stagnation and conformity is the result of the collapse. Only change the production and business operation theory, from the traditional standard tooling cage, manufacturing to meet the market demand, marketable and high efficiency cutting tool is the royal road to learning.

Pay attention to material Improve the quality

In machining, the machining is the most basic and most reliable means of precision machining. Mechanical manufacturing in the 21st century, competition, competition is essentially a precision high speed cutting, the competition is full. At present, with high rigidity integrally cast lathe bed, high speed computing numerical control system and main shaft dynamic balance the adoption of new technology, as well as the continuous development of cutting tool materials, modern cutting technology is moving in the direction of high speed, high precision and strong cutting. The merits of the cutting tool material performance, quality and reliability, directly affect China's millions of expensive manufacturing nc machine tools of high and low production efficiency and processing quality, also directly affect the whole mechanical manufacturing industry production technology level and economic benefits. "Corporate dividend on the blade" vividly represent the position and role of cutting tool in the enterprise.

Cutting tool material is the basis of the cutting tool industry, the development of cutting tool materials for the improvement of the performance of the cutting tool plays a decisive role. Without a good cutting tool material, good cutting tools come from? Efficient cutting come from? In 1900 high speed steel, to improve cutting speed than the original alloy cutting tools by 3 times; The middle of the 20th century to promote the use of carbide cutting tools, and to improve cutting speed is relatively high speed steel by 2 ~ 3 times; Now use the cubic boron nitride and superhard materials such as ceramic cutting tool, and the cutting speed increased by several times. Now cutting tool materials are mainly high speed steel, cemented carbide and three types of superhard materials.

(1) GB/T9943-2008 high speed tool steel high-speed tool steel, high speed steel can be divided into three levels: the low alloy high speed steel (HSS - L), common high speed steel (HSS), high performance, high speed steel (HSS - E). Low alloy high speed steel refers to the tungsten equivalent (W + 2 mo) is less than 12% but it must be high speed steel of 7% or higher. This steel?? Proper heat treatment, hardness can p 63 HRC, twist drill in rolling and machine tap, low-speed cutting tool plays an important role, but the domestic many knives experts disagree, they say the low alloy high speed steel do not meet the requirements of high speed steel performance, suspected of fake and shoddy, reputation in the world is bad, should put it out from the high speed steel. HSS - L since the 1980 s, in fact, in our country so far, in all parts of the country, particularly in jiangsu and zhejiang, fake very rampant, with alloy steel as low alloy high speed steel, knew are not of high speed steel, also on commodities hall marked "HSS", it's not silver three hundred and twenty "here".

HSS - E is on the basis of the HSS appropriately increased Co, V, Al and other elements, and accordingly improve the C, in order to improve the hardness and red hardness. Material price is expensive, but can highlight its when cutting difficult-to-machine materials. Because of nc machine tools and machining center and the rapid development of difficult-to-machine materials, application of HSS - E will gradually increase.

High speed steel powder high speed steel mechanical properties than smelting significantly increased, strength can be increased by 20% ~ 20%, the toughness increased by 1.5 ~ 2 times. And security, reliability and tool life is HSS steel cutting tools are still a few times to dozens times, has long been widely used abroad, but domestic rarely adopted so far.

(2) the hard alloy HSS dominating the cutter materials more than 100 years, nowadays because of the high speed cutting, dry cutting, the fast development of hard cutting, hard alloy became the dominant new cutter materials. Hard alloy by adding rare earth metals in recent years, the application of nano technology, improving strength and toughness of ultra-fine grain cemented carbide and super hard coating technology development and utilization, significantly improve the efficient cutting performance of cemented carbide, greatly broaden the application field of cemented carbide, now efficient advanced tool, is basically cemented carbide of unify the whole country.

(3) superhard cutting tool materials This kind of material is mainly refers to the ceramic, cubic boron nitride, diamond. They have high hardness and wear resistance, it can improve the efficiency of cutting, in recent years gradually expand the application scope of manufacturing. Superhard cutting tool and the material has the production base and domestic suppliers, key questions to see if the user USES the truth. In the mold processing, superhard tool has played an important role, is convinced that this kind of tool material will have a very broad application prospects.

Good cutting tool material must have a good heat treatment as support. Such as the ace of the HSS M42 application is. Current of M42 steel using the misunderstanding between the two: one is blind pursuit of high hardness; Second, the formulation of the heat treatment process. Is not always super hardness superhard high speed steel. M42 steel with proper heat treatment, can achieve 68 ~ 70 HRC, such high hardness is not applicable for most of the cutting tool, cutting tool life has always been not hardness about hero, we pursue high hardness, but not only high hardness, toughness to meet under the premise of high hardness. Is the same type of produce all kinds of high speed steel cutting tools, heat treatment process should be no, namely should advocate the heat treatment process individuation, formulation of heat treatment process already? Out of style.

PVD and CVD surface strengthening technology in cutting tool for major development, even the carbide superhard cutting tools such as icing on the cake. But should keep in mind, again good coating must have a good pretreatment as support, such as low hardness or excessive overheating of high speed steel cutter, the coating will not have good results. So if you want to make good surface strengthening, must play foundation.

Science and technology innovation catching up

"Improve efficiency, reduce cost" is the core of the world manufacturing industry competition, who run companies do not want to make money? Raw materials and energy prices, wages and related charges will be on the rise, the increased cost of product sales price always can't keep up with. All tools industry face the test of the survival and development. So you must struggle to improve labor productivity, go the way of scientific and technological innovation.

Long-term economic strength in the developed countries mainly rely on scientific and technological innovation. According to statistics, in the global science and technology development investment, seven western countries accounted for 90%, of which the investment accounted for more than 70% of the enterprise, so the global intellectual property 80% for all seven countries and multinational companies in the west. With this advantage, developed countries in the industrial chain of high-end technology monopoly capital. Modern tools enterprises, undertaking the important task to improve manufacturing productivity. So developed countries invested heavily in new material and new tool coating, new technology, new technology and tools such as digital manufacture technology for a large number of research and development, to develop generation after generation of efficient tools, firmly occupy the international tool of the high-end market, in domestic has dozens of foreign tool maker operates their red-hot tool. Work in our country, quantity, amount, han worker, heng feng, zhuzhou diamond, xiamen gesac measures are useful, such as well-known tool enterprise, the development of hub slotting cutter milling cutter, carbide gear hob, Christmas tree, octagonal milling cutter, carbide modular knife, wave type vertical milling cutter blade, non-standard slot knife, and adapt to the high speed cutting tool with HSK tooling, double head end handle can be lethal. Although many domestic enterprises have a strong scientific and technological innovation ability, but there is still a large gap compared with foreign famous enterprises. Therefore, increase the intensity of development, the tool innovation as a long-term strategic task to grasp, solid step in the complex, high efficient cutting tool manufacture, to catch up with world powers to make our due contribution.

Strengthen service solid market

For the cutting tool industry, only high quality brand products is not enough, more important is to provide customers comprehensive solution for metal cutting. Cutting tools manufacturers should be as soon as possible from the simple supply standard cutting tools products to produce personalized advanced efficient tool of the strategic shift, and provide services.

Speaking of service, you will naturally think of the product after-sales service, technical service, such as business, but I am here service is an innovative idea, it is related to the enterprise the management mode. In a nutshell, model enterprise?? Material processed into earning processing fee; Development enterprise is sell knives and provide technical; Service-oriented businesses not only sell knives, as well as providing technical support and other services.

Is the practice of some tool manufacturer abroad, for example, this year on April 1, sandvik coromant greater China training center officially opened in chengdu, invite domestic and foreign well-known expert lectures. The efficiency of Shanghai center was founded in 2004, sandvik coromant company has been in tianjin, guangzhou, xi 'an and other places set up training center, and set up the application center in Shanghai. A series of measures, not only can provide users with better training and service, also can communicate and share experiences with industry colleagues, mutual cutting tool industry rapid development.

In today's modern manufacturing increasingly refined, tool enterprises need extension services, increase the service project, improve service levels, this is the key to enhance the competitiveness of enterprises. "Wine is not afraid of deep alley" makes sense, but not comprehensive. Can't underestimate the power of public opinion, advertising. In the planned economy era, the "conveniently small", "instead of" the influence of tool industry is related to the enterprise, has its own tool manufacture workshop, even factory, in addition to purchase some standard items in the market, other tool is solve by ourselves, tool industry think that there is no need to request service. Nowadays, more and more manufacturing, not only to remove the tool shop, and there is not even tool grinding department, even tool engineers and technologists in attrition, its purpose is to highlight the main business and speed up the development, advancing with The Times this is manufacturing a big step forward. But the tools, process of manufacturing the business have to someone tube. To fill the gap that we is tool manufacturing industry, namely specialization. This division of Labour required tools companies dare to innovation, to transcend the traditional tools of after-sales service LaoTaoTao, show the new charm of modern tool enterprises.

In the framework of modern manufacturing, tool path of enterprise development in the future, only by enhancing the all-round service for manufacturing capacity, is likely to be the stability of the manufacturing industry chain partners, stable and reliable in order to gain market share.
