Grinding a stone surface can potentially damage the stone if it is not done properly. The process of grinding involves using a machine with abrasive pads to remove a layer of the stone surface. If the machine or the pads are too abrasive, or if the operator applies too much pressure, it can cause scratches, chips, or deep grooves in the stone.
However, if done correctly, stone grinding can be used to even out and smooth the surface of a stone without causing any damage. It can also be used to remove stains or blemishes, or to make the stone less slippery. In some cases, it's recommended to done by a professional or a trained person who knows the right techniques and has experience working with the specific type of stone you have.
It's also important to note that before start the grinding process, it's important to evaluate the condition of the stone, and what it's going to be used for, in some cases the grinding process may be not necessary or even not recommended.
