Engraving is a combination of drilling and milling in terms of processing principles, and the engraving machine has multiple data input modes as needed. There are two types of computer engraving machines: laser engraving and mechanical engraving, both of which have high power and low power. Low power is only suitable for making two-color boards, building models, small signs, three-dimensional crafts, etc., while carving jade, metal, etc., the power needs to be above 1500W. The high-power engraving machine can be used as a small-power engraving machine. It is most suitable for large-scale cutting, embossing, and carving.
