The principle of these three kinds of engraving machine are the same, three-dimensional engraving machine is generally just add a rotary axis, the other engraving machine is xyz three-axis movement; but in the actual carving of these three kinds of engraving machine are three-axis movement to complete the carving. Three-dimensional engraving machine is generally more general, also divided into wood engraving, stone engraving, metal engraving; woodworking engraving machine is only used with the engraving of wood processing, can also be processed on the organic materials; mold engraving machine is generally in the metal surface engraving, playing log and other patterns. In fact, they can be added to the rotary axis, three-dimensional carving.

Three-dimensional engraving machine is the engraving machine three-dimensional products, woodworking engraving machine is processing wood to do furniture relief hollowing of a class, mold engraving machine is specifically for metal molds
