The first class YAG solid - state laser cutting machine
YAG solid - state laser cutting machine has the characteristics of low price and good stability, but low energy efficiency
Main advantages: can cut other laser cutting machine can cut the aluminum plate, copper plate as well as most nonferrous metal materials, machine purchase cheap, use of low cost, simple maintenance, most of the key technology has been mastered by domestic companies, accessories price and maintenance cost is low, and the machine operation and maintenance simple, requirements for workers personnel quality is not high.
Main disadvantages and disadvantages: can only cut the material below 8mm, and the cutting efficiency is quite low
Main market positioning: cutting under 8mm, mainly for self-use small and medium-sized enterprises and processing requirements are not particularly high most of the sheet metal manufacturing, home appliances manufacturing, kitchenware manufacturing, decoration and decoration, advertising and other industry users, gradually replace wire cutting, CNC punch, water cutting, small power plasma and other traditional processing equipment.
The second type of fiber laser cutting machine
Fiber laser cutting machine because it can be transmitted through the optical fiber, the degree of flexibility is unprecedented, less fault points, easy maintenance, fast, so in the cutting of 4mm thin plate fiber cutting machine has a great advantage, but by the influence of solid laser wavelength it in the cutting of thick plate quality is poor. The wavelength of fiber laser cutting machine is 1.06um, not easy to be absorbed by non-metal, so it can not cut non-metal materials. The photoelectric conversion rate of fiber laser is as high as 25%, and fiber laser has obvious advantages in electricity consumption, supporting cooling system and so on. According to the international safety standards, laser harm grade 4, fiber laser due to the length of the wave on the human body due to the big damage to the eyes, belongs to the largest level of harm, for safety considerations, fiber laser processing needs a fully closed environment.
The main advantages of radium fiber laser cutting machine: high photoelectric conversion rate, less power consumption, can cut stainless steel plate within 12MM, carbon steel plate, is the three kinds of machine cutting the fastest laser cutting machine thin plate, small slit, spot quality is good, can be used for fine cutting.
Major Weaknesses and Disadvantages: Fiber laser most core key technologies are currently in Europe and the United States and other countries of one or two manufacturers, so most of the machines is expensive, most of the machine price in more than 1.5 million, small power is basic in 500000 yuan, due to cutting the fiber slotted very fine large gas consumption (especially in nitrogen gas cutting), In addition, fiber laser cutting machine is difficult or even unable to cut aluminum plate, copper plate and other highly reflective materials, and the speed of cutting thick plate is very slow.
Main market positioning: cutting under 12mm, especially the high precision processing of thin plates, mainly for the addition of high precision and efficiency requirements of manufacturers, it is estimated that with the emergence of 5000W and more lasers, fiber laser cutting machine will eventually replace most of the CO2 high-power laser cutting machine market.
The third type of CO2 laser cutting machine
CO2 laser cutting machine can stably cut carbon steel within 20mm, stainless steel within 10mm, aluminum alloy under 8mm. The wavelength of CO2 laser is 10.6um, which is relatively easy to be absorbed by non-metals. It can cut wood, acrylic, PP, plexiglasses and other non-metallic materials with high quality, but the photoelectric conversion rate of CO2 laser is only about 10%. The CO2 laser cutting machine is equipped with a nozzle blowing oxygen, compressed air or inert gas N2 at the beam outlet to improve the cutting speed and the smooth and clean incision. In order to improve the stability and life of power supply, the discharge stability of high power CO2 gas laser should be solved. According to the international safety standards, laser hazard grade 4, CO2 laser belongs to the least harmful level.
The main advantages of radium CO2 laser cutting machine: high power, general power between 2000-4000W, can cut 25 mm within the full size of stainless steel, carbon steel and other conventional materials, as well as 4 mm within the aluminum plate and 60MM within the acrylic plate, wood material plate, PVC plate, and in the cutting sheet speed is very fast. In addition, because the CO2 laser output is continuous laser, when it is cutting, it is the three kinds of laser cutting machine cutting section effect is the smoothest and best.
Main disadvantages and disadvantages: because most of the core key technologies of CO2 laser are in the hands of European and American manufacturers, so most of the machines are expensive, most of the machines cost more than 2 million, and accessories and consumables and other related maintenance costs are very high, in addition to the actual use of high operating costs, and the cutting gas consumption is very large.
Main market positioning: 6-25 mm thick plate cutting processing, mainly for large and medium-sized enterprises and some of the pure external processing laser cutting processing enterprises, but because of its laser maintenance loss is big, the host can't overcome factors such as big power consumption, its market in recent years by the huge impact solid laser cutting machine and optical fiber laser cutting machine, the market is in a state of obvious atrophy, It is estimated that the CO2 laser cutting machine will be replaced by fiber laser cutting machine after the further development of laser in the future.
In the process of evaluating the laser cutting machine, customers should choose different cutting equipment according to their own needs and cutting purposes.
