As people marvel at the dazzling brilliance of diamonds, the industry has long forged them into the "industrial teeth of modern manufacturing." The Institute of Special Materials Research, through independent innovation of composite material technology and intelligent manufacturing systems, addresses the needs of regional innovation system construction, focusing on core issues such as technical difficulties in the diamond abrasive powder manufacturing industry, process problems, the still imperfect quality evaluation system, and green manufacturing.
They have assembled an interdisciplinary team to carry out an all-chain attack on "material research and development - process development - platform services - industrial transformation." The laboratory phase of new material research and process improvement has been completed, and the corresponding intellectual property has been obtained. The industrialization of technological achievements is now accelerating. Through collaborative innovation along the industrial chain, they are committed to creating a high-end diamond material industry ecosystem and promoting self-controlled development in the superhard materials sector.
Diamond is the hardest known substance in nature (Mohs hardness level 10), with strength over 100 times that of steel! Scientists use high-temperature high-pressure technology or chemical vapor deposition (CVD) methods to combine diamond particles with metal, ceramic, and other matrices to produce diamond grinding wheels, drill bits, saw blades, and grinding tools, giving them the ability to "cut through iron like mud."
Ultra-high hardness: Easily cuts through granite, ceramics, silicon carbide, and other superhard materials.
High temperature resistance and wear resistance: Lifespan is 10-50 times that of ordinary tools, reducing the frequency of downtime replacements.
Precision machining: Surface smoothness reaches the nanometer level, meeting high-precision requirements for semiconductors and optical devices.
Construction and infrastructure: The “diamond wire saw" for cutting marble and concrete aids in large-scale engineering projects; diamond drill bits are used for geological exploration to accurately obtain underground rock core samples.
Automobile manufacturing: Precise grinding of engine blocks and brake discs; cutting and processing of silicon carbide power devices for new energy vehicles.
Consumer electronics: Cutting and polishing sapphire phone screens; ultra-precision cutting of chip wafers with an error of less than 1 micron.
Aerospace: Processing tools for titanium alloy and composite material components, ensuring the lightweight and reliability of aircraft.
Many people mistakenly believe that "diamond abrasive powder" is expensive, but through technological innovation, industrial-grade artificial diamonds have achieved large-scale production.
For example: Embedded diamond abrasive powder: Diamond particles are uniformly embedded in a metal matrix, continuously exposing new particles as they wear, and it is highly cost-effective; Nano-diamond coatings: Depositing micron-level diamond layers on the surface of ordinary tools, balancing performance and cost.
With the development of new materials and intelligent manufacturing, diamond abrasive powder is experiencing a revolution:
Compounding: Combining with silicon carbide, cubic boron nitride, and other materials to cope with extreme working conditions;
Intelligence: Integrating sensors to monitor tool wear in real-time and optimize processing parameters;
Green manufacturing: Low-energy preparation processes to reduce industrial waste emissions.
Although diamond abrasive powder may appear "low-key," it is an indispensable cornerstone of high-end manufacturing. As explorers in the field of special materials, we should continue to dig deep and promote the rapid development of high-end intelligent manufacturing, helping intelligent manufacturing reach new heights!
