[0002] Sapphire is very hard and brittle, making it very difficult to grind and polish both sides of a sapphire wafer. Currently, the grinding and polishing machines used have poor functionality and are often difficult to maintain and load. Furthermore, the grinding fluid naturally flows out through the conduit, resulting in a weak impact and failing to clean the surface of the material, which can easily lead to scratches on the material during operation.
