Opportunities And Challenges Coexist?
I believe that everyone is not difficult to understand. In recent years, with the rapid development of China’s economy, it has also driven the rapid rise of the abrasives industry. The development of this industry is just like the development of economic globalization. It is unstoppable, but we must also One fact that is recognized is that at this moment, the development of the China cutting disc for metal industry is now based on the coexistence of challenges, because we have gradually realized that some problems have been exposed during the development process, such as technology and product innovation, product energy conservation and emission reduction. Such problems have restricted the development of China’s abrasives industry, so how can we make the abrasives industry develop more healthy and orderly? Let us look at the problems we need to pay attention to!
1. The production capacity of enterprises is scattered, the scale is small, and the benefits are low. At present, the scale structure of abrasive abrasive enterprises in China is still not reasonable, the industrial concentration is low, and small enterprises still account for a large proportion;
2, overcapacity, low-grade products homogenization is serious, of which corundum production is particularly prominent;
3. New product research and development capabilities are weak. Domestic abrasive abrasive products are mainly concentrated in the low-end market. The product has low technical content and lacks high-end technology products. It mainly relies on imports and can only meet automobiles, aerospace, machine tools, bearings, locomotives and About one-third of the demand for ships and other industries;
Grinding wheel has a reputation for industrial teeth and occupies a very important position in machining. As far as low price disc for metal is concerned, the following aspects of improvement and breakthrough have extraordinary significance.
The physical structure of the grinding tool is improved, such as increasing the number of abrasive grains per unit time, increasing the average length of the grinding and increasing the grinding contact surface, which changes the amount of grinding time per unit time and effectively improves the efficiency;
Second, the application of superhard abrasives mainly refers to the use of superhard materials such as metal powder, metal oxide or CBN as fillers, and the application of abrasives with resin, ceramic or metal bond. Currently, the superhard abrasive belt High precision, high efficiency grinding results have been widely recognized.
Third, the emergence of new types of grinding wheels, such as micron-sized polycrystalline ceramic microcrystalline abrasives, micro-fine diamond abrasive spherical shell abrasives, ultra-fine polishing polyester film belts, etc. These new grinding wheels have the characteristics of grinding processing advantages Get the most out of it.
