Is the tombstone engraving machine easy to use? How deep can it be carved?

Tombstones can be carved by CNC engraving machine or sandblasting engraving machine. The engraving depth of the two machines is not a problem. The controlled engraving machine needs to use a 5.5 kW head to engrave stone, and the minimum is not less than 3.2 kW. The carving cost will be higher if the carving knife 100 yuan is more. The disadvantage of automatic lettering is that there will be gaps in the fine print, and it is very troublesome to color the engraved words. The sandblasting engraving machine is semi-automatic. However, it is excellent in carving stone tablets and the carving speed is fast. Because it is very convenient to apply protective film, there will be no edge collapse when carving small characters. The biggest advantage is that no matter the size of the stone tablet, it can be carved, which is incomparable to CNC machine tools. The disadvantage is that it is a bit "hard" compared with CNC engraving machine.
