Huamao New Materials: The Star of the Diamond Wheel Industry

Abstract [China Superhard Materials News] On February 27th, Shi Chao, Executive Deputy General Manager of China Superhard Materials Network, led a team of website reporters to visit Henan Huamao New Materials Technology Development Co., Ltd. The company's General Manager Qin Jingchang and Director of the General Office Dong Haiyan warmly welcomed the delegation. Henan Huamao is a subsidiary of Zhengzhou Huajing Diamond Co., Ltd., a listed company in China. Established on July 31, 2012, with a registered capital of 20 million yuan, the company officially started operations on December 1, 2012. Before its official launch, it had already accumulated significant R&D capabilities and technical resources. Equipped with advanced machinery, top-tier technology, and standardized management, the company focuses on producing high-end super-hard abrasives and related tools. Its main products include precision grinding wheels and discs made from diamond and CBN (cubic boron nitride), available in various specifications and bonding agents.

The CBN grinding wheels produced by Henan Huamao are specifically designed for high-precision grinding of automotive parts such as camshafts and crankshafts. These ceramic-bonded CBN wheels use imported binders and are widely used in industries like automobiles, motorcycles, diesel and gasoline engines. They are ideal for grinding materials such as cast iron, carbon steel, alloy steel, and bearing steel. The ceramic-bonded CBN wheels offer advantages including high grinding efficiency, excellent machining accuracy, superior surface finish, long service life, and ease of dressing. These products have already been adopted by domestic manufacturers of camshafts and crankshafts, replacing imported grinding wheels on machines from well-known brands like Japan’s TOYOTA, Germany’s JUNKER, and SCHAUDT.

When discussing the company’s future direction, General Manager Qin Jingchang expressed confidence, stating, “Over the next three to five years, we plan to accelerate our own development while leveraging our capital and technological strengths to drive resource integration within China’s diamond grinding wheel industry.” He added, “Currently, the industry lacks large-scale enterprises, with most players being small workshops focused on single-product lines. Huamao aims to systematically integrate the resources, technology, and market presence of these smaller companies, gradually positioning itself as the leading enterprise in the diamond grinding wheel sector—offering the most comprehensive product range and the strongest technical capabilities.”
