Diamond tools are widely used in various fields such as geological exploration, stone, machinery, automobile and defense industries. The manufacturing technology of abrasive tools, geological drill bits and stone sawing tools for machining has been greatly improved. The products have been serialized and standardized, with complete varieties and specifications, stable product quality, and some products have certain competitiveness in the international market. The vast majority of diamond single crystals are used to make a variety of diamond tools, many of which are available. The diamond sawing tools produced in China have complete specifications and stable quality. According to statistics, in recent years, diamond drilling tools can basically meet the market demand; with the development of the construction industry and the popularity of household air conditioners, for the installation of pipelines and air conditioners and the renovation of old buildings, the demand for diamond thin wall engineering drills for construction The quantity is also increasing. The demand for PDC bits for oil and coal field exploration has also increased accordingly. The quality of diamond composite sheets produced in China is still not enough. It needs further research and improvement, continuously improve product quality, and change the current PDC. The bit depends on the import situation. In the machining process, diamond grinding wheel, PCD tool cutting tool, honing stone, dressing roller, wire drawing die, etc. are widely used; the performance of diamond polycrystalline wire drawing die is better than natural diamond die and hard alloy die, so it is applied in the wire drawing industry. Many, especially the emergence of CVD diamond wire drawing dies, provide a reliable drawing tool for controlling wires up to 15 mm. PCD tools are mainly used for the processing of non-ferrous and non-metallic materials. It is reported that the demand for PCD tools in the automotive, motorcycle, household appliances, wood processing and general machinery industries has increased year by year. Although various diamond tools produced in China have been widely used in various industries and have achieved remarkable economic benefits, their technical level is still different from that of similar foreign products, mainly in: (1) Lack of the entire diamond tool industry Unified management and macro regulation. Due to the blind development, the layout of the entire diamond tool production has been scattered and scattered everywhere. The quality of the products in the tool sales market is unstable, the competition is disorderly, and the price is chaotic. (2) Due to the uncoordinated development of diamond single crystal production and diamond tool production, the development of diamond tools in China lags behind the growth rate of diamond single crystal production, resulting in diamond backlog and slow sales, which affects and restricts the sustainable development of China's diamond industry. The economic benefits of diamond production enterprises have been seriously degraded. (3) The application field of diamond tools is narrow, the product variety is single, the quality is unstable, and some product technical quality standards are more chaotic. There is no unified management standard and standard for product quality inspection and supervision. (4) Diamond tool production equipment and overall technical level are relatively backward, and some advanced new technologies and new technologies are applied slowly. (5) The scale of production enterprises is generally small, production is not concentrated, process technology is poor, market competitiveness is lacking, and economic benefits are not high. (6) Insufficient capital investment in the production of diamond tools, new product development, and process technology research. (7) During the use of diamond tools, the use rate of the base material is low, and the steel is seriously wasted; during the use, abnormal wear, falling off, and residual diamond are more, resulting in lower actual utilization rate of diamond and more waste of diamond material.
