Advantages of cubic boron nitride abrasive
Nov 16,2024
- High hardness and high wear resistance: The hardness of cubic boron nitride is second only to diamond, which makes it easy to cope with the processing of various high-hardness materials, such as bearing steel, cast iron, die steel, tool steel, etc. In the grinding process, the wear rate of the abrasive is extremely low and the service life is long, which greatly reduces the production cost of the enterprise. Compared with ordinary abrasives, the grinding ratio of cubic boron nitride abrasives can be as high as 4000:10000, while ordinary corundum grinding wheels are only 50-80.
- Good thermal stability: Cubic boron nitride abrasive has excellent thermal stability and can withstand high temperatures of 1300-1500°C. In the high-temperature processing environment such as high-speed grinding, it can still maintain good cutting performance, and will not be deformed or worn due to high temperature, thus ensuring the processing accuracy and surface quality. This feature makes cubic boron nitride abrasives widely used in aerospace, automobile manufacturing and other fields that require high precision and quality of parts.
- Strong chemical inertness: For iron, cubic boron nitride is chemically inert and does not carbonize like diamond abrasives when grinding ferrous metal materials. This not only ensures the service life of the abrasive, but also avoids the pollution and damage to the surface of the workpiece caused by the chemical reaction, and improves the processing efficiency and product quality.
- good self-sharpness: Cubic boron nitride abrasive can maintain a sharp cutting edge during use, and the grinding force is small, which is beneficial to improve the accuracy and finish of the parts. At the same time, its self-sharpening can also reduce the number of grinding wheel dressing, save auxiliary working hours, improve production efficiency, especially suitable for high-precision parts of the automatic line processing.
- Low grinding temperature: Due to the high thermal conductivity of cubic boron nitride abrasives, the heat generated during the grinding process can be quickly transferred out, thereby reducing the grinding temperature. Low grinding temperature can avoid the workpiece cracks, burns, tissue changes and other defects, improve the stress condition of the machined surface, and extend the service life of the parts.
- Technological innovation continues to promote product upgrades
- In terms of production technology, enterprises and scientific research institutions continue to increase investment in research and development, and are committed to improving the synthesis efficiency and quality of cubic boron nitride abrasives. For example, by optimizing the high temperature and high pressure synthesis process, the crystallinity and purity of cubic boron nitride are improved, and its performance is more excellent.
- The research and development of new binders is also an important direction of technological innovation. Different bonding agents can give different performance characteristics of cubic boron nitride grinding tools, such as ceramic bonding agent has good chip holding performance and cutting sharpness, metal bonding agent has higher bonding strength and wear resistance. According to different processing needs, enterprises have developed cubic boron nitride abrasives with various binding agents to meet the diversified needs of the market.
- Application areas continue to expand
- With the continuous development of manufacturing industry, the application field of cubic boron nitride abrasive is expanding. In the traditional automobile, machinery, bearing and other industries, cubic boron nitride grinding tools have been widely used. In recent years, with the rise of emerging industries such as electronics, semiconductors, and new energy, the application of cubic boron nitride abrasives in these fields has gradually increased. For example, in the processing of electronic chips, it is necessary to use high-precision abrasive tools to grind and polish the surface of the chip, and cubic boron nitride abrasive tools become the first choice because of their excellent performance.
- The demand for cubic boron nitride abrasives in high-end manufacturing is also growing. Aerospace, national defense and military industry and other fields have extremely high requirements for the precision and quality of parts. The high hardness, high wear resistance and high precision processing ability of cubic boron nitride abrasive just meet the needs of these fields.
- increasingly fierce market competition
- Global cubic boron nitride abrasive market competition is fierce, the main participants include Besco Superabrasives, Sandvik Hyperion, FUNIK and other international well-known enterprises, as well as China's rich Nike, Yellow River cyclone and other domestic enterprises. These enterprises have launched fierce competition in technology research and development, product quality, market share and so on.
- In order to improve market competitiveness, enterprises have to strengthen brand building and marketing. By participating in industry exhibitions and holding technical exchange meetings, enterprises can display their products and technologies to improve brand awareness and market influence. At the same time, enterprises also actively expand sales channels, strengthen cooperation with customers, to provide customers with customized solutions to meet the individual needs of customers.
- high performanceWith the continuous improvement of the manufacturing industry's requirements for processing accuracy and efficiency, cubic boron nitride abrasives will develop in the direction of high performance. In the future, the hardness, wear resistance and thermal stability of cubic boron nitride abrasives will be further improved to meet the needs of high-end manufacturing.
- green environmental protection: In the context of increasingly stringent environmental protection policies, the production and use of cubic boron nitride abrasives will pay more attention to green environmental protection. Enterprises will increase investment in research and development, develop more environmentally friendly production processes and products, and reduce the impact on the environment.
- Intelligent: With the continuous development of intelligent manufacturing technology, cubic boron nitride abrasives will be combined with intelligent technology. For example, by installing sensors on the grinding tools, the wear and processing status of the grinding tools are monitored in real time, and the processing parameters are intelligently adjusted and optimized to improve the processing efficiency and quality.
