English name: Diamond Bruting wheel. Alias "diamond edging grinding wheel, 1A 1 parallel ceramic diamond grinding wheel". It belongs to a ceramic bonded diamond grinding wheel, which is widely used in diamond processing, hence its name. Suitable for polishing natural diamonds. It can replace PDC to process diamonds. It has the same characteristics as diamond and ceramic binder. Compared with ordinary corundum and silicon carbide abrasives, it has stronger grinding force, lower grinding temperature and less abrasive wear. Can adapt to the role of various cooling fluids; When grinding, the grinding tool has good shape retention and high grinding accuracy; There are many pores in the abrasive tool, which is beneficial to chip removal and heat dissipation during grinding and is not easy to block and burn the workpiece; Abrasive tools have better self-sharpening, longer dressing interval and easier dressing. Therefore, some developed countries abroad use ceramic bonded diamond abrasives more and more.
