What are the new product development directions for superhard materials in the next few years? We should conduct serious research on the following aspects, learn from foreign use information, find out the domestic market demand, and formulate a realistic development plan. Our forum grinding machine enthusiasts spontaneously set up the world's only professional grinding industry exchange platform, integrating processing, manufacturing, sales, maintenance, process improvement, technological innovation, relying on all kinds of grinding machine processing and manufacturing as technical support, and build rich and authoritative professional information. platform.
According to the information provided by President Ou Pugui of Osaka Diamond Industry Co., Ltd., the consumption of the world's super-hard abrasive tools market has reached 3.3 billion US dollars, and its stone and construction industry accounts for nearly half of the total, reaching 49.4%; %; composite polycrystalline tools accounted for 18.2%. For this variety of abrasives, CBN abrasives account for 28% of the total abrasives. Compared with the world market, it is obvious that the proportion of domestic market is quite different. First, the proportion of tools used in stone and construction industry is as high as 70% to 80%, which is much higher than the proportion of international market. Second: abrasive tools, CBN The proportion of abrasive tools is low. The reason is that the proportion of one of them is high because there are few high-grade diamonds in China, so many stone tools can only be replaced with low-grade diamonds, resulting in low life of tools such as saw blades; or to increase the diamond concentration in order to achieve a certain tool life. Therefore, it is not the reason why China's stone construction industry is particularly developed. Secondly, because China's processing of cast iron, steel and other abrasive tools are still common abrasive tools, the amount of CBN abrasive tools is very limited, at most can only be counted as the starting stage. Therefore, this piece has great potential for development.
For a long time to come, the automobile industry will continue to develop at a relatively high speed as a pillar industry of the national economy. The development of the automobile industry depends on the improvement of the horizontal processing technology level of the automobile equipment, and the advanced degree of the corresponding processing tools (including the cutting tools and abrasive tools) for the numerical control of the machine tool. Efforts to develop automotive parts processing essential advanced super-hard materials tools, abrasives, abrasives industry to adapt to the development of the automotive industry to promote their own development needs.
In view of the current situation of China's automobile industry, and drawing on the mature experience of developed countries, we should mainly develop: CBN grinding disc for processing piston ring; CBN grinding wheel for high-precision and high wear-resistant bearing processing (including resin ceramic bonding agent); PCBN for processing various cast iron parts Tool grinding tools, honing tools; small hole grinding heads for various hydraulic parts processing; various diamond grinding wheels and set drills for glass processing such as car window glass and automobile rearview mirrors; diamond grinding wheels for processing non-metallic materials of plastics and rubber; CPD cutters for machining aluminum alloy parts; diamond dressing rollers for various purposes.
Hard and brittle non-metallic materials processing
This range is very wide, and the focus should remain on the construction and building materials industry, road transportation facilities and other industries closely related to infrastructure construction. As far as materials are concerned, the focus can be on the processing of wear-resistant floor tiles, glass ceramics, etc.
In the past few years, the domestic wear-resistant floor tile industry has introduced more than 100 advanced production lines (mainly from Italy, Germany, Japan), and the plate grinding rollers, grinding wheels and edging wheel chamfering grinding wheels are all required to be localized. This piece of market has broad prospects and relatively large difficulty. According to relevant statistics, there are only hundreds of floor tile manufacturers in a coastal province. In 1997, imported and processed floor tiles were over 100 million yuan. There are thousands of brick and tile enterprises in the country. In 1995, the production of wall and floor tiles reached 90 million. The development trend of this industry is gradually replaced by wear-resistant floor tiles. Therefore, the processing volume of floor tiles is getting bigger and bigger, and the industry is very useful. Although many diamond products factories have developed processed floor grinding wheels in recent years, they are still not mature enough. The glass industry should focus on the processing of flat glass for various purposes, because it has a large amount of coverage, focusing on the diamond grinding wheel for flat glass smoothing, grinding, chamfering, arc polishing, etc., to achieve the specified processing efficiency on the imported automatic production line. The precision wheel life needs to be invested by the industry and human capital can make a difference. Lighting glass processing has also developed greatly in recent years. The situation in this industry is uneven. There are both very advanced automated processing equipment and relatively backward manual grinding equipment. The lamps need to be processed with few pieces of glass, and more than 10,000 pieces. More than 100,000 pieces, so we should develop different diamond processing tools for different uses, different quality levels and price grades according to market needs.
Ceramic materials have developed rapidly, and have been developed from the past mainly as domestic materials to industrial materials and tool materials. Ceramic materials cannot be processed without diamonds. Although the application of precision ceramics in China is still in its infancy, according to the development trend, the 21st century will surely be widely used as an important member of the new materials industry. Therefore, based on the experience of living ceramics and electronic ceramics processing, we will strive to develop new diamond processing tools to solve the problem of precision ceramic processing.

In our factory, We name those LEDs that can withstand more than 250mA as high power LED. Because of the shape of package, most of through-hole LED cannot handle high current when it's working. In this case, most of high power LED will be package with surface mount device, such as 5050 SMD LED type, 5730 SMD LED type, 2835 SMD LED or high lument package type.
