Advantages of fiber laser cutting machine:


1. Fiber laser has high power-to-light conversion efficiency
The electro-optical conversion efficiency of the fiber laser cutting machine is above 30%. Low-power fiber lasers do not need to be equipped with a cooler. Air cooling can greatly save power consumption during work, save operating costs, and maximize production efficiency.
 
2. The operation and maintenance cost of fiber laser cutting machine is the lowest
When the laser is running, only electricity is needed, and no additional gas is needed to generate the laser; the laser adopts a semiconductor modular and redundant design. There is no optical lens in the resonant cavity and no start-up time is required. It has the advantages of adjustment-free, maintenance-free, and high stability, which reduces the cost of accessories and maintenance time, which is unmatched by traditional lasers.

3. Excellent beam quality of fiber laser cutting machine
The output wavelength of the fiber laser is 1.064 microns, which is 1/10 of the CO2 wavelength. The output beam has good quality and high power density, which is very conducive to the absorption of metal materials. It has excellent cutting and welding capabilities, making the processing cost the lowest.

4. Simple operation of fiber laser cutting machine
The light is output through the optical fiber, which makes the design of the mechanical system very simple and easy to integrate with the robot or multi-dimensional workbench; after the laser is equipped with a shutter, it can be divided into multiple devices through the optical fiber, and divided into multiple channels and multiple units to work at the same time. Convenient function expansion, convenient and simple upgrade.

5. Fiber laser cutting machine saves material and working space
Because the fiber laser is small in size, light in weight, movable in the working position, small in area, and cost-saving; the fiber laser cutting machine adopts computer programming, which can cut products of different shapes and maximize the utilization of materials.

6. The fiber laser cutting machine is safe and environmentally friendly
Laser processing is less wasteful, low noise, clean, safe, and pollution-free, which greatly improves the working environment.
 



Advantages of CO2 laser cutting machine:


1. The cutting quality is good, the cut product is relatively small, and the accuracy is relatively high, the surface treatment effect of the cutting mouth is also very good, and it can be directly welded without processing.
 
2. The cutting speed is fast, because its equipment performance is good, and it is good in all aspects, so the cutting speed is more prominent, the heat affected zone is small, and the deformation may be small; it can cut the full size within 25 mm Conventional materials such as stainless steel and carbon steel, as well as aluminum plates within 4 mm and acrylic plates within 60 mm, wood material plates, and PVC plates.
 
3. It can improve and improve the working environment of the operator. Other laser cutting will cause environmental pollution during the cutting process, while CO2 laser cutting will hardly pollute the environment and is an advanced cutting method.
 
If you understand the application of these two machines, you will find that CO2 laser cutting machines are widely used in non-metal processing, and fiber laser cutting machines are usually regarded as a good helper in metal-related industries. Of course, CO2 laser cutting machine can also cut metal materials, but in recent years it has been gradually replaced by fiber laser cutting machine. Widely used in non-metal processing, and fiber cutters can also cut metal materials, but in recent years they have been gradually replaced by fiber laser cutting machines.


The difference between fiber laser cutting machine and co2 laser cutting machine


1. The laser generator is different: the carbon dioxide laser is a gas molecular laser, and carbon dioxide is used as the medium to transmit the light beam through the reflector. The fiber laser cutting machine uses diodes and fiber optic cables for transmission. Multiple diode pumps generate laser beams, which are then transmitted to the laser cutting head through flexible fiber optic cables. In the CO2 laser technology, the reflector must act in a certain distance, and the laser cutting machine will not be subject to such restrictions.

2. Conversion rate: Fiber laser is the current advanced laser technology. The solid-state laser generator it uses is more efficient than traditional carbon dioxide laser. The photoelectric conversion rate of co2 laser cutting machine is only 8%-10%, while fiber laser cutting machine The photoelectric conversion rate can be as high as 30%, which means that the overall energy consumption of the fiber laser cutting machine is 3-5 times lower than that of the carbon dioxide laser cutting machine, and the energy efficiency is increased by at least 86%, which saves electricity.

3. Cutting ability: The fiber laser has the characteristics of short wavelength, which improves the absorption of the cutting material to the beam. It is more suitable for transmission in a soft optical fiber. Compared with the carbon dioxide laser conducted by mirror reflection, it is flexible and easier to maintain. A 3KW fiber laser cutting machine is equivalent to a 4-5KW co2 laser cutting machine in cutting capacity and speed, which greatly reduces operating costs.

4. Maintenance cost: The structure of the carbon dioxide laser is relatively complicated, and the later maintenance cost is relatively high. The carbon dioxide laser system needs to be cleaned and maintained regularly. Maintenance should be carried out on a regular basis. In addition, the turbine that transports the laser gas must be regularly maintained and refurbished, so the maintenance cost in the later period is very high and complicated. The fiber laser cutting machine is more convenient and environmentally friendly in the later maintenance.



With the development of fiber laser cutting machine and its own advantages, it gradually replaces the market of carbon dioxide laser cutting machine. At present, co2 is mainly used for cutting non-metallic materials, such as cloth, leather, acrylic, and plastic. With the development of high-power fiber lasers, it is gradually occupying the processing market of thick plates.
