The grinding efficiency of both types of grinding wheels decreases with the addition of grinding time. In the early stage of diamond grinding, the grinding wheel has a strong cutting effect and high material removal ability. However, with the addition of grinding time, the cutting effect of the grinding wheel gradually weakens, and the material removal ability of the grinding wheel decreases. At the same time, we can also observe that the initial grinding efficiency of the No.1 diamond flexible grinding wheel is faster, while the efficiency of the No.2 grinding wheel tends to be more stable during grinding.

After 9 hours of grinding with two grinding wheels, a section of the manufacturing sample was cut and analyzed by scanning electron microscopy (SEM). Due to the non conductivity of the diamond and adhesive themselves, the surface of the sample needs to be sprayed with gold to further remind the wear mechanism of the abrasive belt.The technical and economic goals of products such as thin-walled drill bits and diamond grinding wheels all rank at a good level in China, with the production skills and comprehensive product goals of wire saws reaching international advanced levels. The welding strength between the drill teeth of laser welded thin-walled diamond drill bits and the steel body exceeds the German standard (DEA). Diamond grinding wheels have been widely used in China and have entered the international market, with obvious economic and social benefits.Article source: Diamond grinding wheelhttp://www.jm-nanhua.com
