The difference between laser cutting machine and CNC punchin

The laser cutting machine uses the energy released when the laser beam irradiates the surface of the steel plate to melt and evaporate the stainless steel. The laser source generally adopts carbon dioxide laser beam or fiber laser beam, and the working power is 500 ~ 2500 watts. The power level is lower than that required by many household electric heaters, but the laser beam is concentrated in a small area through lenses and mirrors. The high concentration of energy allows the stainless steel to be quickly heated and evaporated locally. In addition, because the energy is very concentrated, only a small amount of heat is transferred to other parts of the steel, resulting in little or no deformation in the laser cutting engineering drawings. Blanks with complex shapes can be precisely cut by laser, and the cut blanks do not require further processing.
 
 
The CNC punching machine can process various sheet metal parts, and can automatically complete various complex hole types and shallow drawing forming processes at one time (it can automatically process holes of different sizes and hole distances according to needs, or it can be stamped step by step through small stamping dies. Shaped large round holes, square holes, waist-shaped holes and curved contours, special processes can also be carried out, such as louvers, shallow drawing, counter-boring, flanging holes, ribs, stamping, etc.). Compared with traditional stamping, it is simple to pass The combination of molds saves a lot of mold costs, can process small batches, diversified products, low cost, short cycle, larger processing range and processing capacity, and timely adapt to market and product changes.
 
 
Comparison of CNC laser cutting machine and CNC punching machine
 
 
　　(1) CNC laser cutting machine can be used for thin and thick plate processing, while CNC punching machine is mainly used for thin plate processing.
 
 
　　(2) CNC laser cutting machine can process all kinds of complex graphics, which can be completed without the limitation of complexity. The CNC punch can only process simple graphics.
 
 
　　(3) The CNC laser cutting machine does not need to open the mold, which is more cost-effective than the products developed by the CNC punching machine.
 
 
　　(4) The automatic tracking system of the CNC laser cutting machine can process on the curved surface, but the CNC punching machine has very high limitations.
 
 
　　(5) CNC laser cutting machine has high processing accuracy, smooth cross section without burrs, CNC punching machine has low processing accuracy and high speed. Suitable for mass  
       production.
