There are currently three main types of laser cutting machines: fiber laser cutting machine, carbon dioxide laser cutting machine and YAG laser cutting machine. Each has its 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 in three kinds of machines, it is the fastest laser cutting machine of the three kinds of machines, with small gaps 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 lasers are in the hands of one or two manufacturers in Europe, America and other countries, so most machines are expensive, most of which cost more than 10,000 yuan. , And the low power is basically 50, about 10,000 yuan, because the fiber slits are very thin when cutting, and the gas consumption is huge (especially in the nitrogen cutting process). In addition, it is difficult or impossible for fiber laser cutting machines to cut high-reflectivity materials, such as aluminum plates and copper plates, and the speed of cutting thick plates is very high. slow.
Main market positioning: The following cutting, especially the high-precision processing of thin plates, is mainly for manufacturers who require extremely high precision and efficiency. It is estimated that with the emergence of lasers and above, fiber laser cutting machines will eventually replace most of the market for CO2 high-power laser cutting machines.
2. Carbon dioxide laser cutting machine:
Main advantages: high power, general power is between -, can cut full-size stainless steel, carbon steel and other conventional materials within 25mm, as well as aluminum and acrylic boards, wood material boards, PVC boards, and thin thin ones within 4mm Time is very fast. In addition, because the CO2 laser outputs a continuous laser, it has the smoothest and best cutting section effect among the three laser cutting machines when cutting.
Main disadvantages and disadvantages: Since most of the core and key technologies of CO2 lasers are in the hands of European and American manufacturers, most of the machines are expensive, most of which are more than 10,000 yuan, and the related maintenance costs (such as accessories and accessories) are also Very expensive. Consumables are extremely high. In addition, in actual use, the operation cost is very high, and the gas consumption is large when cutting.
Main market positioning: 6-25mm thick plate cutting processing, mainly for large and medium-sized enterprises and some laser cutting processing enterprises that are purely external processing. However, due to the large maintenance loss of its lasers, the high power consumption of the host and other insurmountable factors, in recent years, its market has been greatly affected by solid-state laser cutting machines and fiber laser cutting machines, so the market is in a significant contraction. status. It is estimated that after the further development of laser in the future, CO2 laser cutting machine will eventually be replaced by fiber laser cutting machine.
3. YAG solid laser cutting machine:
Main advantages: It can cut aluminum, copper and most other non-ferrous materials that laser cutting machines cannot cut. The purchase price of the machine is cheap, the use cost is low, and the maintenance is simple. Most of the key technologies have been mastered by domestic enterprises, the parts and maintenance are cheap, the machine is easy to operate and maintain, and the quality of workers is not high.
The main disadvantage: It can only cut materials below 8mm, and the cutting efficiency is relatively low.
Main market positioning: cutting into 8mm or less, mainly for self-use small and medium-sized enterprises and sheet metal manufacturing, home appliance manufacturing, kitchenware manufacturing, decoration and decoration, advertising and other industries that do not require particularly high processing requirements, and gradually replace wire cutting, CNC Traditional processing equipment such as stamping, water cutting and low-power plasma.
