I agree with upstairs that it is not used for internal carving. As the name implies, the laser internal carving machine is internal carving, and the laser internal carving machine is used to carve artificially made materials. Transparent materials and ceramics are opaque, and internal carving is meaningless and cannot be carved.

This problem has exactly the same problem on Baidu. If a company says it can carve ceramics, please don't believe it.
