Super hard Henan, turning stone into gold

World diamonds look at China, Chinese diamonds look at Henan. Henan is the birthplace of superhard materials mainly composed of synthetic diamonds. It can not only be polished into exquisite cultivated diamond jewelry, embellishing people's beautiful lives, but also widely used in aerospace, national defense and military industry, high-end CNC machine tools, chip manufacturing, geological exploration and other fields, known as "industrial teeth".

Vacuum brazing technology

Vacuum brazing is one of the effective manufacturing methods for superhard abrasive brazing tools. The most crucial method in the production of superhard abrasive tools using vacuum brazing is vacuum firing technology, and the entire production process of superhard abrasive tool brazing is developed around vacuum firing technology.

Diamond tools

Diamond is widely used in important fields such as cutting, grinding, and parts processing due to its unique chemical structure and unparalleled hardness. Diamond tools mainly include saw blades, cutting heads, drill bits, and other tools widely used in national production. The production processes of diamond tools mainly include sintering, brazing, and electroplating, among which sintering process is the most common and widely used in the production of sintered diamond tools. Sintered diamond tools refer to the process of mixing diamond and binder, obtaining them through compression molding and sintering, where the binder plays an important role. The performance of the tool largely depends on the adhesive formula. The adhesive not only needs to firmly embed the diamond, but also needs to match the wear rate of the diamond. It plays a decisive role in whether the tool can fully and effectively play its role
