[0002] In manual polishing, due to differences in the technical level and experience of the operators, there may be differences in polishing between different gemstones, and even errors and losses. The polishing equipment for gem processing can reduce the risk of human errors and losses and improve controllability through automation. Among them, sapphire among gemstones has a high hardness, second only to diamond. This high hardness enables sapphire to withstand scratches and wear, thereby ensuring the durability and permanence of gem lenses. At the same time, sapphire has a high refractive index, which makes it possible to use sapphire to make gem lenses, such as some gem lenses.
