The main functions of laser engraving machines include permanent marking, engraving and cutting on the surfaces of various materials. 
Laser engraving machines use laser beams to mark the surfaces of various materials. The specific methods include exposing the deeper materials through the evaporation of the surface materials, engraving traces through the chemical and physical changes of the surface materials caused by light energy, or burning part of the materials through light energy, thereby showing the desired pattern or text
In addition, laser engraving machines can also be used to engrave and cut various materials, such as wood products, acrylic, plastic plates, metal plates, stone materials, etc., and the laser causes chemical changes in the materials to achieve the engraving effect
Functional differences between different types of laser engraving machines
UV laser engraving machine: known for its high precision, high speed and flexibility, suitable for the plastic lighting industry. It can engrave clear and detailed patterns and texts, significantly improve production efficiency, and reduce labor costs. 
Picosecond laser engraving machine: Mainly used in the field of skin beauty, it penetrates deep into the skin through the principle of laser, breaks up pigment particles and discharges them out of the body, achieving the effects of removing spots, whitening and tightening the skin. 
Fiber optic machine, ultraviolet machine and carbon dioxide machine: These different types of laser engraving machines are widely used in the water cup industry, and can achieve the engraving of letters, text, graphics, and even 360-degree full cup body engraving.
