Wood laser engraving machines are generally used for cutting and engraving wood processing. The laser engraving of wood materials can be divided into three types: cutting engraving, concave die engraving and punch engraving. The material removal principle of laser engraving is the same as that of laser cutting. Multiple uncut grooves are connected together to form an area of material removal. The cross-section of laser grooving is "V" shaped. The lower the cutting speed and the greater the laser current, the greater the width and depth of the grooving. The influence of the cutting speed and laser current on the depth of the grooving is greater than that on the width of the grooving. much more.
