There are many types of laser processing equipment on the market now, but there are also different types of laser processing. Fiber laser cutting machines and carbon dioxide laser cutting machines are commonly used. However, in recent years, fiber laser cutting machine equipment is gradually replacing carbon dioxide laser cutting machine equipment. What are the differences between fiber laser cutting machines and carbon dioxide laser cutting machine equipment? Today, let's take a look and explore:
1、 The laser generator is different: the Carbon-dioxide laser is a gas molecule laser, and carbon dioxide is used as the medium to transmit the beam through the reflector. The fiber laser cutting machine is transmitted through diodes and fiber optic cables. Multiple diodes pump the laser beam, which is then transmitted to the laser cutting head through flexible fiber optic cables. In carbon dioxide laser technology, the reflector needs to act at a certain distance, and laser cutting machines are not subject to such limitations.
2、 Conversion rate: fiber laser is an advanced laser technology at present. Its solid-state laser generator is more efficient than the traditional Carbon-dioxide laser. The photoelectric conversion rate of the carbon dioxide laser cutter is only 8% -10%, while the photoelectric conversion rate of the fiber laser cutter is as high as 30%, which means that the overall energy consumption of the fiber laser cutter is 3-5 times lower than the overall energy consumption of the carbon dioxide laser cutter, improving the energy efficiency by at least 86%, This saves a lot of electricity.
3、 Cutting ability: Fiber laser has the characteristic of short wavelength, which improves the absorption of the cutting material to the beam, making it more suitable for conducting in fine and soft optical fibers. Compared to carbon dioxide laser conducted through mirror reflection, it is more flexible and easier to maintain. A 3KW fiber laser cutting machine is equivalent to a 4-5KW carbon dioxide laser cutting machine in cutting capacity and speed, greatly reducing operating costs.
4、 Maintenance cost: The structure of the Carbon-dioxide laser is relatively complex, and the maintenance cost in the later period is relatively high. The carbon dioxide laser system should be cleaned and maintained regularly, and the reflector should also be cleaned and calibrated regularly. Moreover, due to the purity of the carbon dioxide gas, the resonator should also be maintained regularly. In addition, the turbine that transports laser gas also needs regular maintenance and refurbishment, which makes the maintenance cost in the later stage very high and complex. The fiber laser cutting machine is more convenient and environmentally friendly for later maintenance.
With the development of fiber laser cutting machines and their various advantages, they are gradually replacing the market for carbon dioxide laser cutting machines. Currently, carbon dioxide mainly cuts non-metallic materials such as fabric, leather, acrylic, plastic, etc. With the development of high-power fiber laser technology, it is gradually occupying the processing market of thick plates.
