The beginning of 2000, the world saw blade industry manufacturing to Asia. The blade factory in China and South Korea. The main blade manufacturing in China is mainly to middle and low blade. 2000 annual industry average rate of about 30% in the development. The industry is concentrated in Hebei, Jiangsu Danyang Quanzhou, Fujian, Hubei Ezhou. Its downstream customers are mainly concentrated in stone mining, processing and woodworking machine tools, especially the stone before the industry saw blade consumption.
First, the current production process
Its manufacturing process, the cutting of the matrix, the surface of the grinding heads welding. Cutting the main processing methods, small blade, stamping mainly in the large blade, water jet cutting and laser cutting, including silencer slot cutting; welding technology hot then welding, high frequency welding and laser welding, which laser welding technology is the basic standard of the saw blade industry export the welding process.
Second, laser cutting and welding equipment needs of the current situation
In the exhibition in Beijing on March 38 enterprises blade enterprise survey for medium and large blade matrix industries accounted for 20% of future plans to do enterprise blade matrix of 6%, 74% of the matrix, dependent on outsourcing, with no intend to do the plans of the matrix; do the large and medium-sized substrate cutting 71% of the enterprise has a laser . The future, saw the matrix, the company will consider laser cutting equipment. 50% of the enterprises in the survey of eight enterprises in the production of large and medium-sized blade matrix in the laser cutting equipment additions to the state. Do medium-sized blade body in accordance with the current rate of development of the saw blade industry every two years will Qiugou a laser cutting equipment can be found from the data. Companies surveyed in the procurement of foreign equipment is relatively small, the main procurement Wuhan Fali Lai cutting systems engineering limited liability companies, domestic enterprises equipment.
Welding equipment survey data, 33 percent of the saw blade has a laser welding machine, 13 percent of companies are Buying a laser welding machine, 13 percent of the company\\ s future plans to buy a laser welding machine, 41 percent of businesses not currently clearly the intention of the company. Market share in terms of which 54 percent of the market in Germany Feiyu, Wuhan Jinshi Kai has 27% market, other companies (Wuhan Fali Lai, etc.) accounted for less than 2% of the market. Laser welding technology is an export of the technical threshold of the saw blade industry, product and low grade watershed collar than laser cutting, so a lot of blade desire to buy laser welding, laser welding equipment company will select the outside processing .
Third, the hard materials industry development status
Blade industry is a major consumer of hard materials industry, the hard materials industry in 2005, although internal and external difficulties, but still achieved a total industrial output value, sales revenue growth rate of 26%, a small amplitude slow the still rapid growth. Product mix improved significantly, a substantial increase in technical level, production costs have fallen dramatically. The cut-throat competition of diamond saw blades for many years led to the 2005 U.S. anti-dumping battle of Diamond Saw Blade; grasp the rapid development of advanced powders and indirect heating method of producing diamond enterprise, causing a \"big reshuffle\" of the diamond-producing enterprises, a large number of technology research and development behind, unable to grasp the advanced manufacturing technology companies has been eliminated. The high wind and waves, the stormy situation has flooded a lot of enterprises, to exercise and improve as the industry as a whole, with international advanced level, the largest amount of times a high quality diamond products have made a breakthrough and has high volume production. the end of the unique cubic press not produce 30/35 and to the history of the coarse high grade products, aroused the close attention of the international counterparts, and completely changed the situation of the international peer contempt diamond equipment and technology, world-renowned two of the three diamond factories in China, cubic presses the production of diamond technology procurement and research, and another is re-sold part of its diamond industry.
