In terms of new varieties, a diamond abrasive called CSD variety has emerged, that is, the agglomerate structure diamond is different from the conventional diamond single crystal particles in that it is composed of a plurality of fine particles. When the grinding force reaches a certain level during the grinding process, these fine particles will be slightly broken, so the self-sharpness is very good, the grinding is very sharp, the efficiency is high, the service life is longer, and the surface quality of the workpiece is better. CSD abrasive is most suitable for processing hard alloys, and can also be used for processing glass and ceramics; it is most suitable for resin bond abrasives, and can also be used for bronze and ceramic bond abrasives. Cubic Boron Nitride (CBN) Abrasives With the development of technology, CBN abrasives have developed two varieties of amber single crystals with better strength and toughness based on the past two black single crystal varieties. There are two varieties of micro-powder, which form a total of nine varieties, which greatly expands the variety of CBN and its application range. On the basis of Ni, Cu and Ti plating products, the plated products have developed a variety of superhard materials coated with corundum. The product features: hard and brittle corundum (or silicon carbide) as the coating, and the coating is "thorn" shape". This kind of product is applied to resin bond super-hard abrasives, which not only has the advantages of Ni-plated and Cu-based abrasives, but also overcomes the disadvantages of high plating cost and dullness of tools, processing efficiency is increased by 30% to 35%, and service life is improved by 20 %. The future development trend in the 21st century will be the era of knowledge economy. The integration of knowledge and economy and the integration of the global economy have brought us opportunities, but more are challenges and a sense of urgency. Facing such opportunities and challenges, with the joint efforts of industry colleagues, we believe that China's super-hard materials products will surely achieve greater development:
(1) With the continuous improvement of technologies such as raw material preparation, new binders, special production equipment and testing instruments, the manufacturing technology level of super-hard materials will be greatly improved, new varieties will emerge continuously, with high speed and high thickness. Products with ultra-thin, complex profiles and other features will continue to develop at a higher level, and product quality will be significantly improved.
(2) Super-hard material products will develop in the direction of serialization, standardization and specialization, and each production enterprise will form its own product features.
(3) The application technology of super-hard materials, including CNC machine tools, dressing technology, special grinding fluids, etc. will be developed and improved.
(4) The application fields of super-hard materials will be expanded to a large extent, and more applications will be obtained in the fields of automobiles, computers, microelectronics, optoelectronics, telecommunications, home appliances, new ceramics, etc., CBN products will get bigger. Popularization and development.
(5) With the transfer of the world manufacturing center to mainland China, China's super-hard materials will develop rapidly in the next 10 years, not only will production leap to the forefront of the world, but also the technological level will move toward a world power.
China's superhard materials industry is developing rapidly
Since the birth of China's first synthetic diamond in 1963, China's superhard materials and products industry has gone through 40 years of development. Over the past 40 years, the technology and quality of superhard materials and products in China have been continuously improved, the variety of products has been increasing, and the scale of production has been continuously expanded. It has formed a cross-sector, cross-industry and cross-regional research, design, production, and complete categories. A complete industrial system of considerable scale has created a development path for the super-hard materials and products industry with Chinese characteristics. At present, China's synthetic diamond production ranks first in the world, becoming the world's largest producer of superhard materials, and has achieved its due status in the world's superhard materials industry. According to incomplete statistics, in the four years from 1998 to 2001, the total output of China's superhard materials and products industry increased from 400 million carats to 1.62 billion carats, of which the output of products increased from 0.5 billion carats to 290 million. Carat, nearly five times more, the development speed is gratifying. New developments in superhard materials are the driving force and purpose of material development and application, while superhard materials are the main raw materials for products, and its development provides the basis for the development of products. In recent years, major advances in the variety and quality of superhard materials include: diamonds in high-grade single crystals. With the large-scale development of diamond synthesis equipment, the synthesis of powdered catalysts and powdered carbon materials has been widely promoted. The development and application of composite pressure transmitting media, the proportion of high-strength diamonds has increased year by year. A key enterprise has been able to mass produce high-end products equivalent to BS950 or above, with a ratio of more than 20%, a proportion of high-end products to 42%, and an economic benefit of two-thirds.
