Zhengzhou major scientific and technological research project diamond grinding wheel passed the appraisal
Zhengzhou Abrasives Research Institute in Zhengzhou City recently completed the identification of a key scientific and technological research project titled "Processing Diamond Tools for Hard and Brittle Materials – High-Thickness Metal Bond Diamond Grinding Wheel." The project has received positive feedback from the expert appraisal committee, who highlighted its significant achievements and practical applications.
The research team addressed four major technical challenges. First, they developed a specialized metal bond formulation by carefully selecting and combining different metal powders, which is particularly effective for processing high-aluminum ceramics and NdFeB magnetic materials. Second, they solved the issue of uneven axial density in the working layer of high-thickness grinding wheels, ensuring more consistent performance. Third, by improving the surface treatment of the grinding wheel’s outer circumference and optimizing the bonding process between the base body and the grinding ring, they significantly enhanced the bonding strength, preventing the grinding ring from falling off during use. Finally, through the application of cutting-in technology, they determined optimal processing parameters that ensure the straightness of the grinding wheel.
The project's innovations include solving the problem of axial uniformity in high-thickness metal bond grinding wheels and developing an advanced combination technology for the working layer and the substrate. These advancements not only improve the efficiency and quality of machining hard and brittle materials but also contribute to the broader development of diamond tool technology in China.
This breakthrough marks a significant step forward in the field of abrasive tools and is expected to have wide-ranging applications in industries such as aerospace, electronics, and precision manufacturing.
