Discuss and analyze the difference between CNC laser cutting machine and CNC punching machine: easy to choose between the two

　　Numerical control equipment is now the mainstream of processing equipment. The intelligent working method is more accurate and simple, so more and more customers choose it. The most widely used CNC equipment is CNC laser cutting machine and CNC punching machine. These two types of equipment are indispensable for metal processing. What is the difference between the two CNC machine tools? We will compare and introduce them.

　　 CNC 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 usually uses a carbon dioxide laser beam or a fiber laser beam with a working power of 500 to 2500 watts. Although the power level is lower than that required by many household electric heaters, the laser beam is focused into a narrow area through lenses and mirrors. High concentration of energy can evaporate stainless steel through rapid local heating. In addition, because the energy is so concentrated, only a small amount of heat is transferred to other parts of the steel, so there is little or no deformation in the laser cutting process. The use of lasers can cut blanks with complex shapes very accurately, and the cut blanks do not require further processing.

　　 CNC punching machine can be used for the processing of various sheet metal parts, and can automatically complete a variety of complex pass and shallow stretch forming processing at one time. Automatically process holes of different sizes and pitches according to your requirements. Small punches can also be used step by step. The punching method punches out large round holes, square holes, waist-shaped holes and curved contours of various shapes, after blind, shallow stretching, countersunk holes, flanges and other special process treatments. Make holes, ribs, embossing, etc. The simple mold combination saves a lot of mold costs compared with traditional stamping. It can process small batches and a variety of products, with low cost, short cycle, large processing range, strong processing capacity, and adapt to the market.

Comparison of 　　 CNC laser cutting machine and CNC punching machine:

　　(1) CNC laser cutting machine can process thin and thick plates, while CNC punching machine is mainly used for thin plate processing.

　　(2) The CNC laser cutting machine is not limited by complexity and can process various complex graphics. The CNC punch can only handle simple graphics.

　　(3) The CNC laser cutting machine does not need to open the mold, and the cost is greatly reduced compared with the products developed by the CNC punching machine.

　　(4) The automatic tracking system of the CNC laser cutting machine can process curved surfaces, but the CNC punching machine has very high limitations.

　　(5) CNC laser cutting machine has high processing precision, smooth cutting surface without burrs, low processing precision and high speed, suitable for mass production.

　　 CNC laser cutting machine and CNC punching machine are very different in the process of processing products. The former is not restricted by complicated conditions and has high accuracy, while the latter has more restricted conditions and relatively low processing accuracy. In the actual selection, you need to analyze it according to the specific situation.
