Laser internal carving machine is a laser device used for internal carving of crystal crafts and other materials, which can achieve three-dimensional carving. It is achieved by combining the principles of galvanometer and Z-axis mechanical movement.

Laser engraving machines, generally used for flat engraving, such as leather and printing plates, use external xy operating mechanisms to drive the laser machine for engraving operations.

Laser marking machine is a marking principle that uses a computer-controlled galvanometer to drive the laser beam to move in the XY direction, achieving light engraving of markings on the surface of objects.
