At present, Laser cutting machine mainly fiber Laser Cutting Machine, carbon dioxide laser cutting machine and YAG laser cutting machine:
1. FIBER LASER CUTTING MACHINE: main advantages: high photoelectric conversion, low power consumption, can cut less than 12 mm stainless steel and carbon steel plate. It is the three kinds of machine cutting thin plate fastest laser cutting machine, cutting seam small, good quality light spot, can be used for fine cutting. Main disadvantages: At present, most of the key technologies of fiber laser are in the hands of one or two manufacturers in Europe and America, so most of the machines are relatively expensive. The price of most machines is over 1.5 million yuan, and the price of low-power machines is around 500,000 yuan. Because the fiber in cutting the slit is very small, gas consumption is very large (especially when nitrogen cutting) . In addition, the high cost of fiber laser, laser cutting machine is difficult or even unable to cut aluminum, copper plate and other high-reflective materials, cutting thick plate is very slow. The main market positioning: cutting 12mm below, especially the high-precision processing of thin steel plate, mainly for high precision and efficiency requirements of the manufacturers. It is estimated that with the emergence of 5000W and above laser, fiber laser cutting machine will eventually replace most of the CO2 high-power laser cutting machine market.
2. CO2 LASER CUTTING MACHINE: main advantages: high power, general power between 2000-4000W, can cut full-size stainless steel, carbon steel and other conventional materials within 25 mm, also can cut aluminum plate within 4 mm, acrylic plate within 60 mm, wood plate, PVC plate, the cutting speed is very fast. In addition, because the output of CO2 laser is continuous laser, its cutting effect is the smoothest and the best among the three Laser Cutting Machines. Major downside: Most of the key technology for CO2 lasers is in the hands of European and American manufacturers, so most of the machines are expensive, most of them more than 2 million. In China, only powerful manufacturers invest heavily in developing core technologies. Main Market Orientation: 6-35mm plate cutting, mainly for large and medium-sized enterprises and some pure external processing of laser cutting enterprises. In recent years, its market by solid-state laser cutting machine and fiber laser cutting machine great impact on the market in a significantly shrinking state. However, some cash-rich companies are still on the market, retaining a private plot of land for China's core technology.
3. YAG SOLID LASER cutting machine: main advantage: can cut aluminum plate, copper plate and most other laser cutting machine can not cut Non-ferrous metal material. The machine is cheap to buy, low to use and easy to maintain. Most of the key technologies have been mastered by domestic enterprises. Spare parts and low maintenance costs, machine operation and maintenance is simple, the quality of the workers is not high. Main disadvantages: can only cut 8mm below the material, cutting efficiency is relatively low. Major market positioning: cut less than 8 mm, mainly for their own use and most customers in sheet metal manufacturing, home appliances manufacturing, kitchenware manufacturing, decoration, advertising and other industries processing requirements are not particularly high, gradually replace the traditional WEDM and other processing equipment, CNC punch, water cutting, low-power plasma and so on.
