What are the advantages and disadvantages of the laser cutting machine market?

At present, laser cutting machines are mainly fiber laser cutting machine, carbon dioxide laser cutting machine and YAG laser cutting machine, respectively, advantages and disadvantages and market positioning:

1. Fiber laser cutting machine:

·Main advantages: high photoelectric conversion rate, low power consumption, can cut stainless steel plate and carbon steel plate within 12mm. It is the fastest laser cutting machine of these three machines, with small cutting seam and good spot quality, which can be used for fine cutting.

·Main disadvantages and disadvantages: at present, most of the core key technologies of fiber laser are in the hands of oneortwo manufacturers in Europe and America, so most of the machines are expensive, most of which are more than 1.5 million, and the small power ones are about 500000 yuan. During cutting, the fiber cutting is very small and the gas consumption is huge (especially in nitrogen cutting), In addition, it is difficult to cut aluminum plate, copper plate and other high reflection materials, and the speed of cutting thick plate is very slow.

·Main market positioning: cutting below 12mm, especially high precision processing of thin plates, is mainly aimed at manufacturers with high requirements for precision and efficiency. It is estimated that with the appearance of 5000W or above lasers, fiber laser cutting machine will eventually replace the large market of CO2 high power laser cutting machine.

2. CO2 laser cutting machine:

·Main advantages: high power, general power is between 2000-4000w, can cut 25 mm of stainless steel, carbon steel and other conventional materials, as well as aluminum plate within 4 mm and acrylic plate within 60mm, wood material board, PVC plate, and in cutting sheet speed is very fast. In addition, because the CO2 laser outputs continuous laser, it is the smoothest and best cutting section effect in the three laser cutting machines.

·Main disadvantages and disadvantages: most of the key technologies of CO2 laser are in the hands of European and American manufacturers, so most of the machines are expensive, and most of the machines are more than 2 million. Only powerful manufacturers in China invest a lot of funds in R & D of core technology.

·Main market positioning: 6-35mm plate cutting and processing, mainly for large and medium-sized enterprises and some laser cutting and processing enterprises that are purely processed externally. In recent years, the market has been greatly impacted by solid laser cutting machine and fiber laser cutting machine, and the market is in a state of obvious shrinkage. But some enterprises with capital are still doing market, and they keep a piece of land for China's core technology.

3. YAG solid state laser cutting machine:

·Main advantages: aluminum plate, copper plate and most non-ferrous metal materials that can not be cut by other laser cutting machines. The machine is cheap in purchase price, low in cost and simple in maintenance. Most of the key technologies have been mastered by domestic enterprises, and the price and maintenance cost of accessories are low, and the operation and maintenance of the machine are simple, and the quality requirements for workers are not high.

·Main disadvantages and disadvantages: only cutting materials below 8mm, and cutting efficiency is relatively low.

·Main market positioning: cutting below 8mm, mainly for the self-use small and medium-sized enterprises and most of the customers in the industry such as sheet metal manufacturing, household appliances manufacturing, kitchen utensils manufacturing, decoration, advertising, etc., gradually replace traditional processing equipment such as wire cutting, numerical control punch, water cutting, low power plasma and so on.
