**Abstract**
The 2nd China (Zhengzhou) International Abrasives and Grinding Exhibition took place successfully at the Zhengzhou International Convention and Exhibition Center from November 15th to 17th. This year’s event was a major milestone, with Huanghe Cyclone Company showcasing an impressive exhibition space of 322 square meters—nearly six times larger than their previous participation in the Sanmao Exhibition, which covered just 54 square meters. The company's expanded presence reflected its growing influence and commitment to the superhard materials industry.
This year, multiple divisions of the company participated, including the Superhard Materials Division, Superhard Composites Division, Superhard Wheel Materials Division, Metal Powder Division, Precision Tool Division, and others. Additionally, departments such as the Machinery Manufacturing Division, Electromechanical Manufacturing Division, Cyclone International, Yellow River Electric, and Tanaka Kemei Pressure Equipment were also present, highlighting the breadth of the company's operations and technological expertise.
Huanghe Cyclone made a strong impression with its booth, drawing significant attention from visitors. The company presented its latest innovations, including large single-crystal diamonds known for their high hardness, excellent wear resistance, and superior thermal conductivity. These materials are ideal for ultra-precision cutting applications, used in metal processing, non-ferrous metal turning, and various composite materials. Their products received widespread praise at the exhibition.
The Superhard Wheel Material Manufacturing Division, a wholly-owned subsidiary of Huanghe Cyclone, has over a decade of experience in producing superabrasive materials. It maintains long-term technical cooperation with leading research institutions and experts from Japan and Germany. The division specializes in diamond micro-powder, cubic boron nitride, and other advanced materials.
The Electromechanical Manufacturing Division focuses on PDC drill bits for oil, geological, and coal mining industries. With advanced technology and comprehensive testing systems, the division ensures high-quality performance. Its products have gained a strong reputation both domestically and internationally.
The Metal Powder Manufacturing Division, established in 2005, has grown into a key player in the industry. With a production capacity of 12,000 tons annually, it offers a wide range of powders used in diamond synthesis, saw blades, grinding wheels, and more. The division's products are exported globally and are highly regarded for their quality and reliability.
As the 50th anniversary of China’s superhard materials industry approached, Huanghe Cyclone stood as a symbol of the sector’s growth—from modest beginnings to global recognition. The company now leads the market, with synthetic diamond output surpassing that of all other countries combined. The "Cyclone" brand is recognized worldwide, and the company continues to expand into higher-end, international markets.
