CNC engraving machine: suitable for cutting electroplated products, PMMA, hardened PC and aluminum parts
CNC machining accuracy: ＜ 200mm size ± 0.05mm, 200-400mm size ± 0.1mm
CNC engraving and stamping process comparison:
① The flatness of the product edge: CNC ＞ stamping, there is burr at the cutting edge of the stamping part, which is not very smooth and flat, and there will be a horizontal and vertical line like indentation at the cutting edge; CNC products, such as stainless steel and aluminum parts, have bright and neat traces of knife path on the surface
② Adaptability of product forming: CNC ＞ punching, punching can only cut materials with certain willfulness, such as PC, aluminum, stainless steel, etc., but cannot cut surface hardened materials, such as hardened PC, PMMA, plating, etc
③ Capacity: blanking ＞＞ CNC. In terms of product forming capacity, blanking is far greater than CNC. At the same time, blanking can be performed with adhesive backing; CNC can not be molded with glue, and it needs a single piece of glue
④ Die cost: punching ＞＞ CNC, the cost of hardware die used for punching is higher, generally forming at 3-5K, and the cost of special processes such as embossing and bending is higher; CNC tool cost is about 100

Stamping machine: suitable for sheet work, used for punching large size products, metal parts, aluminum plates, stainless steel parts, etc
Punching machine accuracy: the punching machine accuracy mainly depends on the mold accuracy, and the common molds are wood mold, etching mold, carving mold, and five metal mold
PC parts: ＜ 150mm overall dimension ± 0.075mm, 150-250mm tolerance is not less than ± 0.1mm, and the maximum punching size of the product is 300 * 600mm (theoretical value)
Metal parts: ＜ 150mm overall dimension ± 0.05mm, 150-250mm tolerance is not less than ± 0.075mm, and the maximum punching size of the product is 300 * 600mm (theoretical value)

Die cutting machine: suitable for coiled material operation, used for punching adhesive tape, PET film, PC material with thickness less than 0.5mm, labels, copper foil/aluminum foil and other products
Precision of die-cutting machine: the precision of die-cutting machine mainly depends on the precision of mold. The common molds are wood mold, rubber plate mold, etching mold and carving mold
＜ 150mm overall dimension ± 0.075mm, 150-250mm tolerance is not less than ± 0.1mm, and the maximum punching size of the product is 400 * 400mm (theoretical value)

Laser cutting: It refers to the energy released when the laser beam shines on the surface of the workpiece to melt and evaporate the workpiece, so as to achieve the purpose of cutting and carving. It has the characteristics of high precision, fast cutting, not limited to the cutting pattern, low processing cost, etc.
Scope of cutting products: laser cutting is applicable to cutting adhesive backing, electroformed film, aluminum foil, copper foil, and generally LOGO uses laser forming process; Not applicable to high-temperature melting products, such as PC, foam, silica gel, etc
Laser cutting accuracy:
＜ 150mm overall dimension ± 0.03-0.05mm, 150-250mm tolerance is not less than ± 0.05-0.075mm
