The application of diamond tools in the field of stone processing in China has achieved great success through nearly two decades of development. Diamond chips, grinding discs and shaped tools for stone processing have gone through nothing, from imitation to substitution of imported products. The products are sold to the evolution of the world. Take Fujian Province as an example. It was the first province to produce tombstones exported to Japan. Tombstones ordered by Japanese merchants in the 1990s have high gloss requirements and precise dimensional requirements. Therefore, the quality of processed diamond tools is relatively high. These products are mainly imported from Japan Sanhe Co., Ltd., such as diamond resin grinding discs, diamond metal grinding discs, polishing discs and soft grinding discs. The technical difficulty of these abrasives is in order of easy to difficult: diamond metal grinding discs, diamond resin grinding discs, polishing discs, soft grinding discs, especially polishing discs or polishing sheets, which are the most technically difficult. The main difficulty is that the gloss of the polishing should reach a certain level within a certain period of time, and the gloss should be clear and bright. Therefore, the order in which the market began to replace imported products at the time was also started from the metal grinding disc, and experienced a development process from easy to difficult. At the beginning of the domestic production of 8 inch 50# metal grinding discs to the user's unit price of about 400 yuan (currently as long as 30 yuan), eventually several domestic manufacturers in the polishing disc gloss technical problems, since 1994, Stone diamond tool abrasives can basically replace imported products. However, due to disorderly price competition, product prices have been declining year by year, and this competition has also extended to neighboring countries in Asia. In the Indian market in 1999, the export price (FOB) of the 2m ordinary low-cobalt diamond cutter head produced in China was about 450 US dollars, and has now dropped to about 150 US dollars. Due to low-price competition, the production cost of products has been declining, but the average profit level of the industry has also decreased year by year. Since the beginning of this year, on the one hand, the state has made macro adjustments to the industrial structure. On the other hand, the influence of external conditions has caused the following unfavorable factors for export-oriented enterprises: the depreciation of the US dollar against the RMB has directly caused the profits of enterprises to fall; the tax rebate rate has decreased, and the value-added tax paid has increased. The US subprime mortgage crisis caused the US market to be weak; prices have risen and corporate operating costs have increased. Despite all the above disadvantages, there are also great opportunities for development. The adjustment of the national industrial structure has a positive and positive effect on the upgrading of product quality. Facing the challenges of internal and external environment, the development of China's diamond tool industry is to improve product quality, improve scientific and technological content, and participate in the world market with innovative and high-quality products. Competition has made China's diamond tools have a place in the world market. An American dealer once said: China's product quality is now close to that of South Korea's products, as long as it works in two aspects: first, the quality stability of the product, and second, the improvement of the details of the product. If these two points improve, the competitiveness of diamond tools will be greatly enhanced, and the future of China's diamond tools in the world market will be unquestionable. The depreciation of the dollar is not only a problem facing China, but also a problem faced by countries such as South Korea. At present, the diamond tool market in the world of stone processing industry has a greater brand advantage in Europe and Japan. The diamond tool products of the Korean stone industry still dominate in the world, especially in Europe and the United States: stable quality and large market share. For example, in the US market, the most prominent position in the dealership is the Japanese-made or Japanese-branded products, and it is understood that the sales of Korean products are large because the prices of Korean products are moderate. Some Korean products (including those made in China) have created their own brands in the international market. However, with the increasing quality of Chinese products, more and more foreign dealers have come to China to find competitive products.
