Fiber laser cutting technology has only appeared in the last 3 to 5 years. Although many companies are just beginning to understand this technology, they are also beginning to realize the difference between fiber laser cutting and the more common carbon dioxide laser cutting. With the continuous improvement of cutting technology, fiber laser cutting has become one of the most advanced technologies in the industry.
Thermal energy cutting methods mainly include flame, plasma, and laser cutting technologies. Laser cutting can achieve the best cutting quality, especially for fine features and hole cutting with a diameter and thickness ratio less than 1: 1. As a result, laser cutting technology has become the most suitable method in the industry for demanding strict fine cutting. In the field of laser cutting, fiber laser cutting has attracted a lot of attention because it not only provides the speed and cutting quality that can be achieved by carbon dioxide laser cutting, but also significantly reduces maintenance and operating costs. So this makes fiber laser cutting promising, and many experts believe that it will soon replace other laser cutting systems.
The main advantages of fiber cutting
In carbon dioxide laser cutting technology, carbon dioxide gas is the medium that generates the laser beam. However, fiber lasers are transmitted through diodes and fiber optic cables. The fiber laser system generates a laser beam through multiple diode pumps, and then transmits it to the laser cutting head through a flexible fiber optic cable instead of transmitting the beam through a mirror. This has many advantages, the first being the size of the cutting bed. In gas laser technology, the reflector must be set within a certain distance. Unlike it, fiber laser technology has no range limitation. And even the fiber laser can be installed next to the plasma cutting head of the plasma cutting bed. The carbon dioxide laser cutting technology does not have this option. Similarly, when compared with a gas cutting system of the same power, the system appears more compact due to the ability of the fiber to bend.
The most important and significant advantage of fiber cutting technology should be its energy efficiency. With the complete solid-state digital module and single design of the fiber laser, the fiber laser cutting system has higher electro-optical conversion efficiency than carbon dioxide laser cutting. For each power supply unit of the carbon dioxide cutting system, the actual general utilization rate is about 8% to 10%. For fiber laser cutting systems, users can expect higher power efficiency, between 25% and 30%. In other words, the overall energy consumption of the fiber cutting system is about 3 to 5 times less than that of the carbon dioxide cutting system, which improves the energy efficiency to more than 86%.
Fiber lasers have short-wavelength characteristics, which increase the absorptivity of the cutting material to the light beam, and enable cutting of non-conductive materials such as brass and copper. A more focused beam produces a smaller focus and a deeper depth of focus, so that fiber lasers can cut thinner materials faster and more efficiently cut medium thickness materials. When cutting materials up to 6mm thick, the cutting speed of a 1.5kW fiber laser cutting system is equivalent to the cutting speed of a 3kW carbon dioxide laser cutting system. Because the operating cost of fiber cutting is lower than the cost of a common carbon dioxide cutting system, this can be understood as an increase in output and a reduction in commercial costs.
There are also maintenance issues. Carbon dioxide gas laser systems require regular maintenance; mirrors need to be maintained and calibrated, and resonators need to be maintained regularly. On the other hand, fiber laser cutting solutions require almost no maintenance. The carbon dioxide laser cutting system requires carbon dioxide as the laser gas. Due to the purity of the carbon dioxide gas, the resonance chamber will be contaminated and needs to be cleaned regularly. For a multi-kilowatt CO2 system, this cost at least $ 20,000 per year. In addition, many carbon dioxide cuttings require high-speed axial flow turbines to deliver laser gas, and turbines require maintenance and overhaul. Finally, compared to carbon dioxide cutting systems, fiber cutting solutions are more compact and have less impact on the planet, so they require less cooling and significantly reduce energy consumption.
The combination of less maintenance and higher energy efficiency makes fiber laser cutting and carbon dioxide laser cutting systems emit less carbon dioxide and are more environmentally friendly.
