The laser in the laser engraving machine is its core. Generally speaking, the scope of use of laser engraving machine is wider, and the engraving accuracy is higher and the engraving speed is faster. Compared with the traditional manual engraving method, laser engraving can also make the engraving effect very delicate, which is no less than the craftsmanship level of manual engraving.
