Laser erosion is the removal of thin layers from a workpiece. The process removes very fine layers with maximum precision. Laser erosion is used if a workpiece with a layer structure must be eroded layer by layer at certain points.

The advantage of laser Etching engraving is that it can engrave very fine patterns very well. This en-graving method is mainly used for engraving artificial leather embossing rollers, PVC wallpaper embossing rollers, and film sheet embossing rollers. This type of engraving uses chemical corrosion raw materials, which is not conducive to environmental protection. At present, there are fewer and fewer factories in China that do this kind of carving. Another disadvantage is that the depth of this kind of engraving is generally not deep.
