Physical structure difference between the two laser cutting machines:
In the physical characteristics of CO2 laser cutting machine, CO2 gas is the material that causes laser. However, fiber lasers are transmitted according to diodes and optical cables. The fiber laser system is made up of several diodes and hydraulic plunger pumps. The laser is then transmitted to the laser cutting head according to the flexible optical cable rather than the bathroom mirror. This has many advantages. The first is the size of the cutting machine. In the CO2 laser machine, the reflection lens must be set within a certain distance. The two are different, and the fiber laser equipment is endless. In addition, the fiber laser can even be installed beside the plasma cutting head of the plasma cutting machine. Similarly, compared with the vapor laser cutting system with the same output power, the system is more and more compact because of the bending ability of chemical fibers.
Optical fiber cutting machine has higher photoelectric conversion efficiency:
The most important and significant advantage of fiber laser cutting machine is its high conversion efficiency. The fiber laser cutting system has a detailed solid-state data control module and a single design scheme of the fiber laser, and its efficiency is higher than that of the CO2 laser cutting system. For each switching power supply module of the CO2 laser cutting system, the specific utilization rate is about 8% ~ 10%. For the fiber laser cutting system, customers can estimate higher output power efficiency, about 25% to 30%. In other words, the overall energy consumption of the fiber laser cutting system is about three to five times lower than that of the carbon dioxide laser cutting system, raising the energy consumption level to above 86%.
Comparison of actual effect of laser cutting:
The fiber laser has the characteristics of light wave length, which improves the digestion and absorption of light by the drilling raw materials, and can be laser cut like red copper, copper and non-conductive raw materials. The more concentrated light causes a smaller focus and a deeper focus, so that the fiber laser can quickly laser cut thinner raw materials and more reasonable laser cut Rongheng raw materials. When the raw material is laser cut to 6mm, the laser cutting speed of the 1.5KW fiber laser cutting system is equal to that of the 5kW laser cutting system. Therefore, the operating cost of fiber laser cutting is less than that of the conventional carbon dioxide laser cutting system.
Maintenance cost comparison:
Fiber laser cutting is more environmentally friendly and convenient in equipment maintenance. It is necessary to maintain the CO2 laser system, carry out maintenance and correction of the reflective lens, and carry out maintenance and repair of the resonator. On the other hand, the fiber laser cutting solution requires very little maintenance. The carbon dioxide laser cutting system must use carbon dioxide as the laser vapor. Because of the purity of carbon dioxide vapor, the common vibration cavity will pollute the environment and must be cleaned on time. For a multi kW carbon dioxide system, there should be at least 120000 per year. In addition, many CO2 laser cutting regulations require high-speed axial-flow turbine engines to transport laser steam, and turbine engines must be maintained and repaired.
To sum up, although the CO2 laser generator has a strong laser cutting ability, the fiber laser cutting machine still occupies a high advantage in terms of environmental protection, energy saving and cost. The economic benefits of the fiber laser cutting machine are far higher than that of CO2. In the future development trend, the fiber laser cutting machine will occupy the influence of popular machinery and equipment.
