Industry news
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

Discussion on the classification and development of abrasives and abrasives
Abrasive tool is a tool for polishing, grinding, and polishing. Most mills are artificial mills made of abrasives and binders, which are natural mills directly processed from natural minerals and rocks. Grinding stones are not only widely used in mechanical manufacturing and other metal processing industries, but also in food processing, paper industry, and the processing of non-metallic materials such as ceramics, glass, stone, plastic, rubber, and wood.
