To understand the difference between ordinary engraving machines and laser engraving machines, we must first understand what are ordinary engraving machines and laser engraving machines. Ordinary engraving machine refers to the equipment that uses the tool on the engraving machine to cut and engrave materials; laser engraving machine refers to the equipment that uses the melting, evaporation and photochemical reactions generated by the laser beam on the surface of the material to make the surface of the material turbid and achieve the desired pattern.
