The development of laser technology in saw blade industry

1. The current production process Its manufacturing process mainly includes the cutting of the substrate, the grinding of the surface and the welding of the cutter head. At present, the main processing methods of cutting are small saw blades, mainly stamping, medium and large saw blades, water cutting and laser cutting, as well as cutting with muffler grooves; the current welding technologies mainly include thermal welding, high frequency welding and laser welding, among which Laser welding technology is currently the basic standard for welding processing exported by the saw blade industry. Second, the current situation of laser cutting and welding equipment demand In a survey of 38 saw blade companies at the Beijing Exhibition in March, 20% of the industry is doing medium and large saw blade substrates, 6% of companies plan to do saw blade substrates in the future, and 74% of the companies rely on outsourcing. Plans to make substrates; 71% of large and medium-sized substrate cutting companies have laser cutting machines. Companies that plan to make saw blade substrates in the future will consider laser cutting equipment. Among the 8 companies surveyed that produce large and medium-sized saw blade substrates, 50% of the companies are in the state of adding laser cutting equipment. From the data, it can be found that according to the current development speed of the saw blade industry, companies that make large and medium-sized saw blade bodies will need one laser cutting equipment every two years. The surveyed enterprises currently purchase relatively few foreign equipment, and mainly purchase equipment from domestic enterprises such as Wuhan Farley Cutting System Engineering Co., Ltd. (Huagong Laser Brothers). According to the effective data of the welding equipment survey, 33% of saw blade companies have laser welding machines, 13% of companies are looking for laser welding machines, 13% of companies have plans to buy laser welding machines in the future, and 41% of companies currently The company's plans are unclear. In terms of market share, German Feiyu has 54% of the market, Wuhan Jinshikai has 27% of the market, and other companies (Wuhan Farley, etc.) account for less than 20% of the market. Because laser welding technology is a technical threshold for the saw blade industry to export, and it is also a water divider for the high and low grades of products, many saw blade companies have a greater desire to purchase laser welding than laser cutting. At present, companies that do not have laser welding equipment will choose external processing. . 3. Development Status of China's Hard Materials Industry The saw blade industry is the main consumer industry of hard materials. In 2005, the hard material industry, despite internal and external troubles and many difficulties, still achieved a growth rate of 26% of the total industrial output value and sales revenue, with a slight slowdown, but still a high growth rate. The product structure has been significantly improved, the technical level has been greatly improved, and the production cost has been greatly reduced. Due to the vicious bargaining competition of diamond saw blades for many years, the US anti-US diamond circular saw blade dumping war in 2005; the rapid development of enterprises that master advanced powder and indirect heating methods to produce diamonds has caused a "big reshuffle" of diamond production enterprises. A large number of companies that are backward in technology research and development and fail to master this advanced manufacturing technology have been eliminated. Although this turbulent situation has submerged many enterprises, it has been tempered and improved as a whole industry. The second-grade diamond products with the international advanced level and the largest amount have made breakthroughs and have been put into production in batches. It ended the history that China's unique six-sided top press could not produce 30/35 and high-grade products, which attracted the attention of international counterparts and completely changed the situation that international counterparts despised China's diamond equipment and technology. Two of the three major diamond companies have set up factories in China and started to purchase and research the technology of China's six-sided top press to produce diamonds, and the other has resold its diamond industry.
