Li Chunfa, the manager of Feimeng Diamond Zhengzhou Office, shared his insights during an interview: "At present, information plays a crucial role in enterprise development. The Second Sanzhan Exhibition is not only a showcase of cutting-edge technology and advanced products in the industry but also serves as a key platform for industry information exchange. It holds significant guiding value for the company’s future growth. He also highly praised the role of China's Superhard Materials Network in promoting the development of the superhard materials industry. The two parties engaged in a productive discussion on the latest technological developments and innovations, including diamond micropowder and its coating technologies."
**China Henan Feimeng Diamond Industry Co., Ltd.**
**Henan Feimeng Diamond Industry Co., Ltd. participated in the 2nd Sanmei Exhibition.** The company has adopted advanced technology, modern equipment, and strict quality management, and it has achieved ISO9002 international certification. While expanding production, Feimeng places great emphasis on technological innovation and new product development. It has a team of experienced experts and owns independent intellectual property rights. The company has established long-term partnerships with Hunan University, Tsinghua University, and the National Superhard Materials and Products Research and Development Technology Center. Its products, such as fine-grained boron-containing diamond and bright black high-strength cubic boron nitride, have been recognized as national high-tech products. Feimeng has received the title of High-tech Enterprise from the Henan Science and Technology Department and is home to the Engineering Research Center of Superhard Abrasive Materials in Henan Province. Approximately 90% of its products are exported to countries such as the United States, Japan, Germany, and South Korea. The company primarily produces industrial synthetic diamonds, cubic boron nitride, and super-hard abrasive micro-powders for grinding applications, offering three main series with multiple varieties.
**Feimeng Resin Binder Diamond Abrasive**
The PDG series of synthetic diamonds is a polycrystalline superhard abrasive used mainly in resin-bonded grinding wheels. Feimeng's boron-doping technology significantly enhances the bonding strength of the PDG series, increasing the holding power of the crystals. These polycrystalline particles consist of irregularly shaped substructures with rough surfaces, ensuring excellent performance with high grinding efficiency, long service life, and superior finish. Resin-bonded diamond offers several advantages:
1. Sharp cutting angle that maintains continuous self-sharpening. Under consistent grinding force, the particles tend to break along the subcrystal interfaces. As worn subcrystals detach, new sharp subcrystals form, maintaining a sharp edge without full granule detachment. This process continues until the granules are fully removed, resulting in high efficiency and abrasive utilization.
2. Excellent surface finish due to uniform brittleness, preventing scratches and burn marks on the machined surface.
3. Long service life thanks to the rough surface and recessed corners, which allow the binder to grip the particles effectively.
4. Minimal internal stress on the workpiece, leading to improved durability and performance.
Resin-bonded diamond provides high grinding performance and low resistance, making it suitable for both wet and dry grinding of hard materials. Common binders include phenolic or polyimide resins, with special binders used when necessary. Additives enhance the adaptability of the resin system, and the optimal bond-abrasive match is essential for precision grinding, high gloss, and efficiency.
Resin-bonded diamond is ideal for processing carbide tools, wire drawing dies, ceramics (such as silicon nitride, porcelain, alumina, and silicon carbide), and glass.
**Feimeng Cubic Boron Nitride Products**
CBN, or cubic boron nitride, is the second hardest abrasive after diamond and offers superior thermal stability. It does not react with iron-based materials, making it ideal for grinding ferroalloys and aerospace materials.
**Superhard Abrasive Powder**
Superabrasive micropowders are widely used in fine grinding, polishing, and super-polishing applications. Feimeng is a leading domestic producer of high-quality polycrystalline diamond, cubic boron nitride, and single-crystal diamond micropowders. With expertise in super-hard abrasive micropowder production, Feimeng implements 6S, 5S, and ISO9002 management throughout the production process. The production line is equipped with advanced instruments such as morphology analysis systems, plasma ICP detectors, laser particle size analyzers, and SEMs. Quality control spans all stages, from crushing and shaping to grading, purification, identification, storage, and transportation. Feimeng’s coating technology for micropowders is also at the forefront, offering high surface roughness, excellent uniformity, and precise particle size distribution.
