How to distinguish between dry grinding discs and water grinding discs?

1. The damage to stone is different: because the water polishing plate grinds deeper, it is less likely to have scratches, and there will be no dust. Dry grinding is relatively shallow compared to polishing, with a larger amount of dust and a higher risk of scratches.

2. The production materials are different: the water grinding disc is made of artificial diamond particles, while the dry grinding disc is made of high-temperature resistant resin.

3. Different glossiness: The two have different degrees of heat generation during the polishing process, and the glossiness of high-temperature polishing is different from that of natural temperature polishing. The glossiness of the water mill is softer and more beautiful. Dry grinding discs may burn the surface, causing valve stem erosion, and insufficient transparency.

4. The difficulty of subsequent processing varies: dry grinding discs generate a large amount of dust during the polishing process, which can pollute the stone and have an impact on the body, while water grinding discs reduce dust and have a smaller impact on the environment.
