CNC engraving machine is a kind of small CNC machine tool. Now CNC engraving machine basically has all the characteristics of CNC machine tool (including automatic tool change, four axis and five axis). It consists of three parts: mechanical part, control part and software part. It represents the development direction of today's mechanical and electrical products. Mechanical and electrical products are increasingly moving towards the integration of these three technologies. Whoever can integrate well will have the best Potential, can win the market finally.

CNC engraving comes from manual engraving and traditional CNC machining. It has the same points with them, but also has some differences. Like any advanced production technology, CNC engraving always absorbs the advantages of manual engraving and traditional CNC machining as much as possible while making up for the shortcomings of them, and integrates them to gradually form the characteristics of CNC engraving.

(1) Machining object of CNC carving. The main processing objects of CNC carving are characters, patterns, textures, small complex surfaces, thin-walled parts, small precision parts, irregular art relief surfaces, etc. the characteristics of these objects are: small size, complex shape, fine finished products.

(2) CNC carving process characteristics. Due to the small and complex engraving area, CNC engraving mainly uses small cutting tools with sound less than 6.0mm for fine machining.

(3) CNC engraving products have high dimensional accuracy and good product consistency. This is of great significance for mold engraving and batch product processing with precise size requirements.

(4) Low labor intensity, high degree of automation, less dependence on operators. According to the machining instructions, the control system automatically controls the cutter movement of CNC engraving machine, accomplishes the engraving task, and greatly reduces the labor intensity. This highly automated process greatly reduces the dependence of production on traditional manual carving operation skills.

(5) The principle of CNC engraving is high speed milling. Compared with traditional CNC machining, CNC engraving is similar to high-speed milling II] II. CNC engraving is a kind of processing method with high speed, small feed and fast cutting, which is vividly called "eat less and run fast".
