30 years of development China saw industry

Saw in the origin and development of our country has a long history. The first saw in the Stone Age, multi-purpose stone. In the shang and western zhou dynasty saw the made of bronze, a history of more than 3000 years ago. Saw is an indispensable tool in people's life and production, saw teeth of modern industry, it accelerated the pace of human progress, and promote the development of high-tech industries.

1953 germans invented the first circular saw blade in the world, after Europe became a circular saw blade, the main production base of alloy saw blades and diamond saw blade, they occupies a large share in the high-end market, dominated the development of the world saw industry. High-grade circular saw blade is mainly produced in Germany, Japan, Italy and other countries. Due to the backward production technology and production equipment, mainly low-standard products manufactured by other developing countries. With the development of industrialization, the rapid development of industrial developed countries in the aspect of saw blade manufacturing, especially the machinery in one of the leading enterprises in the world of the saw blade. Modern sawing industry scale production starts late in our country, in the early 1950 s began to appear domestic woodworking circular saw blade manufacturer, then saw blade is not alloy, mainly used in forestry and wood processing industry, the production technology and scale cannot be compared with the developed countries. Due to specific social, very slow in the sawing industry of our country s development, technical team is not growing, production levels cannot be improved, then saw industry is the low levels of repetitive production in our country, so that the saw blade in China market almost occupied by imported products, especially the alloy saw blade long-term rely on imports.

After the reform and opening up, the world saw blade manufacturing began to shift to Asia, by the mid - 1990 - s, due to the vigorous development of the collective economy and private economy, sawing industry in our country also to the way of rapid development, the industry development speed every year at about 30%. Products also by a single development to multipurpose woodworking circular saw blades, multi-function, many series, many varieties of saw blade system, like carbide saw blade, diamond saw blade, such as garden saw blade in infrastructure, in areas such as agriculture, landscape, architecture and life plays an important role. After 30 years of reform and opening up, the domestic many industries such as furniture, aluminum products, building materials, plastic, electronic, walk to the world's highest which brought historic opportunity to saw, saw blade products in addition to satisfying the growing domestic market in China, quite a number of exported to international markets and market of form a complete set of electric tools. After 30 years of struggle, by sawing industry of our country, backward technology, low yield, develop a poor now saw blade production the largest country in the world, China is already the world largest production base of alloy saw blades and diamond saw blade.

The development of these years, our country saw blade manufacturing enterprises in zhejiang, jiangsu, Shanghai, guangdong, hebei, hubei and shandong and other provinces and cities formed clusters, have sprung up a group of "production base" and "the hometown of hardware". Jiangsu danyang saw blade production after more than 20 years of development, now has 79 production enterprises, the production of various types of saw blade in danyang, 2006, 50 million, one-third of the total of the saw blade production and sales of nearly 1.5 billion yuan, total danyang has become the largest production base of low-standard saw blade, emerge a number of relatively good small and medium-sized enterprises. Yongkang is the national famous hardware capital ". Hardware industry is a pillar industry of yongkang, the city has more than 10000 hardware machinery, products cover mechanical hardware, decoration hardware, architectural hardware, tools, hardware and so on more than 10000 varieties, including 1/3 of the total export amount of saw blade. Commodity radiation domestic and Russia, the United States, Canada, Brazil, Australia, Japan, etc. More than 50 countries and regions.

Technological advances and the emergence of the new technology to promote the sawing industry development in China. In 1961, our country the first ruby laser, successful development after just a few years, the rapid development of laser technology, produced a series of advanced achievements. The various types of solid, gas, chemical and semiconductor lasers have been developed. At the same time, as a high brightness, high directivity and high quality excellent properties such as the new light source, laser quickly applied to the technical field, showing strong vitality and competitiveness. Since the reform and opening, laser technology obtained the unprecedented development opportunity. For 30 years, our country in the development of high power laser has made great achievements, the developed laser power has reached and exceeded the watt, formed the laser welding, cutting, drilling, surface treatment, cladding and rapid prototyping manufacturing, direct forming, dozens of applications such as lithography process, in the automotive, electronics, aerospace, machinery, metallurgy, railway, shipbuilding and other industries widely used. Laser cutting of matrix in the saw blade production, grinding, welding, sound of the cutting tools on the surface of the groove cutting etc. More and more widely applied, the cutting precision and welding fastness is unmatched by traditional process, greatly improving the product quality and production efficiency. Welding technology at present mainly have heat welding, high frequency welding and laser welding, including laser welding technology is currently a saw blade welding industry export processing basic standards.

Since 1923, when the hard alloy as a kind of important tool material and structure material, has been eighty years of history. In the late 1960 s, west Germany Krupp company successfully developed a coating cemented carbide, it is a major progress of cemented carbide production technology. This with chemical vapor deposition method, the ordinary carbide blade coated with a thin layer of hard compounds (such as TiC, TiN, etc.) and the coating blade, under the high speed cutting cast iron and steel, can be more than the uncoated cemented carbide blade life several times, and cutting speed can be improved from 25 to 30%, so it will soon get a wide range of industrial applications. In the world today is in the sale of indexable tool is about more than half is the use of carbide coating. With the development of science and technology, the purpose of the carbide becomes more and more widely, people will become more and more high requirement for the performance of cemented carbide. Cemented carbide products is to develop in the direction of motors, miniaturization, the miniature auger bit, bitmap print wire, precision mold and other high-tech products. Cutting tool is becoming more and more high dimensional accuracy requirement. Sawing industry is a major consumer of hard material industry, sawing industry development and growth and hard material are inseparable, with the improvement of hard material quality, quality of saw blade and the cutting efficiency increases.

Grinding is an important part of the saw blade use, saw blade grinding quality directly determines the quality of saw blade. Our country is the grinding method, one of the oldest countries in the ancient science book the characterized by open content, there is a "slice, Cuo, cut, grinding" words, including "grinding" is refers to grinding. For nearly 30 years, our country to improve the precision of the grinding machine, enhance the automation of grinding, developing high speed grinding, improve the precision and smoothness, superhard abrasives and so on a series of achievements, the variety has become increasingly diversified, specialized, the increasingly fierce competition. In recent years, remove to the ultra-precision grinding, high efficiency and develop in the direction of superhard abrasive, automation is one of the important direction of the development of grinding technology. Many domestic enterprises have developed specifically for saw blade grinding equipment, saw blade grinding machine, according to the degree of automation is divided into semi-automatic and fully automatic saw blade grinding machine; According to the purpose can be divided into side saw blade grinding machine, cutting-edge saw blade grinding machine, etc. The emergence of the saw blade grinding machine to speed up the pace of the automation of saw blade production, saves the manpower, improve the production efficiency, and product quality has risen steadily.

Saw blade is a kind of composite metal processing and mechanical processing process technology products, a high technology content. Improve product quality, increase product added value, creating brand is the development trend of sawing industry of our country. Although the saw blade production in our country in the top, but most are cheap saw blade, the production is still in the stage of manual, semi-automatic, labor intensive industries. China saw the quality of products and a large gap compared with developed countries in the international market competitiveness is not strong enough. Thus to product development and technical innovation, improve production efficiency and product added value, in order to improve the saw blade products in the international competitiveness of our country. Some enterprises with less resources, the production technology condition is not perfect, many process USES the manual operation, not only increased the personnel cost and management cost, also does not favor the product quality is stable. Instead of half since the device, with automatic production equipment and manual operation, is saw a direction of the industry development in our country. Such as automatic welding welding gear tooth machine instead of mobile phone, there will be greatly improved in the efficiency and quality, using automatic gear grinding machine instead of semi-automatic gear grinding machine, etc., the use of a large number of automation equipment to increase the product technology content, liberated the productive forces, promote the industry development.

Saw blade in the production of a variety of technical composition, special materials such as steel, hard alloy saw industry has yet to be developed, many related technologies in the sawing industry development in our country will gradually increase. Laser technology will play an important role in the saw blade production in the future, there are a lot of companies choose the laser welding machine and laser cutting machine, the advantages of this technology is of high precision, less waste. More and more used in high precision grinding machine in the production of saw blade, now with many of the grinding machine precision is not enough in our country, in order to improve the quality of our products will encourage domestic production grinding machine enterprises to improve technology, improve the precision grinding machine, to meet the requirements of the saw blade production enterprises, some enterprises will import high precision grinding machine.

China's current production of saw blade in the world belong to cheap products, low value-added products, export enterprises advantage is low price, dosage of piling up profits. This phenomenon will get change, now more and more enterprises attach importance to product quality, improve product quality to strategic position, and the enterprise no longer generic and set up its own r&d team.

China saw industry from scratch, since the childhood, from weak to strong, has experienced ups and downs, the back of the road is very long, we believe that the Chinese saw industry will go to the world!
