Diamond is commonly known as "diamond diamond", which is a diamond we often say. It is a mineral composed of pure carbon and is the hardest substance in nature. Diamond is an indispensable raw material for the production of abrasive tools, power tools and other hardware tools. After long-term development, China has formed four major manufacturing bases and distribution centers for domestic diamond tool products alongside Shijiazhuang, Jiangsu Zhenjiang, Fujian Quanzhou and Hubei Ezhou. Shijiazhuang, Hebei, led by leading enterprises, Shijiazhuang City is one of the national diamond tool manufacturing bases. At present, there are about 100 large and small diamond tool manufacturing enterprises in the city, of which 40 are enterprises above designated size with an annual output value of more than 5 million yuan. There are 3 enterprises with 100 million yuan. According to incomplete statistics, the number of employees in the diamond tool industry in Shijiazhuang City is more than 10,000. The main products are small saw blades for architectural decoration, engineering thin-wall drill bits, sintered grinding discs, etc. The annual output value of diamond tools in the city is more than 1 billion yuan. It is understood that the overall diamond tools in Shijiazhuang City are mainly domestic market, supplemented by foreign countries, including the domestic market all over the country, with a market share of more than 10%; foreign countries with European and American developed countries as the export direction. There are three diamond production enterprises with an annual output value of more than 100 million yuan in Shijiazhuang: Shijiazhuang Boshen Tools Co., Ltd., Hebei Fushi Huakaikai Diamond Tools Co., Ltd. and Hebei Xiaobe Tools Group Co., Ltd. Shijiazhuang City's export diamond tools are mainly saw blades. According to the Superhard Materials Branch of the Machine Tool Industry Association, the foreign market capacity of diamond saw blades has reached RMB 25 billion. In recent years, customs data shows that China's annual export of diamond saw blades should be At around 300 million US dollars, about 2 billion yuan. Therefore, the structural space of foreign markets is still very large, and the export prospects are very broad. Under the leadership of the development of leading enterprises, Shijiazhuang diamond tool industry has advanced by leaps and bounds, occupying an irreplaceable position in the country. However, compared with developed countries, the diamond-related products in Shijiazhuang City are still quite different from the technical and equipment level of the industry, the specialization and serialization level of the product varieties, and the performance and quality level of the products. File upgrades are imperative. Jiangsu Zhenjiang - Zhenjiang, Danyang of the China saw township is famous "township of Chinese saw." After nearly 20 years of development, the Danyang Export Hardware Tools Industry started in the late 1980s. Its raw materials, finished product production, sales, transportation and warehousing have formed a one-stop industrial system. It is reported that the rear lane hardware tools enterprises total about 300-400, the entire lane of the entire Danyang City with an annual output of nearly 3 billion twist drills, more than 60 million diamond saw blades, is the largest diamond saw blade and drill bit production in Asia. At the base, the high-speed tool steel required for the drill bit accounts for one-half of the world's total. Similar to the development of the diamond tool industry in Shijiazhuang, Danyang hardware tools industry also has strong leading enterprises, namely Tiangong International and Feida Group. Among them, Tiangong International successfully boarded the main board of the Hong Kong Stock Exchange in August 2007. Although there are two leading enterprises that “open up the worldâ€, in general, there are still some problems in the Danyang tool industry. For example, the technological content of products is not high, mostly in the middle and low grades, the market competitiveness is not strong, and the profits are weak. Faced with the grim situation, how to seek survival and development in the face of adversity has become the top priority of Danyang saw blades. Quanzhou, Fujian – another “split†in the industrial chain For the outside world, Quanzhou’s most famous industrial project is “stoneâ€, which has the largest stone production and processing base in the country. It is precisely because of the rapid development of the stone industry that it has driven the development of related industries such as local diamond saw blades. At present, Quanzhou diamond tool industry has become a major domestic production base, forming a complete and independent industrial chain. As one of the major diamond tool production bases in the country, Quanzhou has more than 100 diamond tool manufacturers, with an annual output value of more than 1 billion yuan. The sales volume and sales volume have increased by more than 22% per year. But it is such a powerful economy, but there is no strong enterprise. Problems such as relatively weak industrial base, small scale of producers, lack of original innovation in industrial technology, and serious shortage of innovative talents have gradually exposed, and have become the main constraints hindering industrial development. Hubei Ezhou - China's first diamond cutter in the first town compared to the first three, Hubei Ezhou diamond cutter is particularly young. The diamond tool industry in Ezhou is mainly concentrated in Yanji Town, and the development of the town's industry is derived from the technology brought back by the villagers. In 1980, Zhang Zhongming made a stone business from the Egang Group, but the diamond tools used for cutting were imported from Japan at an expensive price. After nearly a year of hard work, he developed an original diamond cutter and set up a saw blade factory. This technology has also been “proliferated†in Yanji Town. Since 1988, many Yanji people who have mastered production technology have also Started to invest and set up factories around the country, and formed three “Yanji Tool Towns†in stone production areas such as Yunfu in Guangdong, Shuitou in Fujian, and Laizhou in Shandong. It is understood that the diamond tool industry employs more than 10,000 people, more than 700 large and small enterprises, artificial diamond tool products account for more than 60% of the national market share, has become the country's largest synthetic diamond tool production base, Yanji Town was also confirmed For the "first town of Chinese diamond tools."
