If you’ve ever wondered how those amazing fiber laser cutting machines work, then this blog is for you! We’ll take a look at the science behind these machines and how they can cut through just about anything. So sit back, relax, and get ready to learn about one of the most incredible machines ever created.
1.How do fiber lasers work?
Fiber lasers are a type of laser that uses a long, thin strand of glass or quartz as its lasing medium, as opposed to the more common gas, liquid, or crystal used in other types of lasers. Fiber lasers are capable of producing high-quality beams for cutting and welding applications.
The fiber laser gets its name from the fact that it uses a long, thin strand of glass or quartz as its lasing medium. The length of the fiber determines the wavelength of the laser light produced. The advantage of using a fiber as the lasing medium is that it can be easily coupled to an optical fiber for delivery of the light to the workpiece.
Fiber lasers are capable of delivering high-quality beams for cutting and welding applications. The main advantage of fiber lasers over other types of lasers is that they are much more efficient, meaning they use less energy to produce the same amount of power. Additionally, fiber lasers can be easily modulated to produce pulses of light, which allows for greater control over the cutting or welding process.
2.How do fiber lasers cut?
Fiber lasers emit a very high-quality beam of light. This beam is then focused into a tiny point using a lens, which is then used to cut through the material.
The advantage of using a fiber laser is that it can cut through even the thickest materials with ease, and it can also do so at very high speeds. In addition, fiber lasers are much more energy-efficient than traditional laser cutting machines, which makes them ideal for use in industrial settings.
3.The advantages of fiber laser cutting
Fiber laser cutting machines have become increasingly popular in recent years due to their many advantages over traditional cutting methods.
Fiber lasers are more efficient than CO2 lasers, with electricity-to-light conversion rates of up to 80%. They also generate very little heat, which means there is less distortion of the material being cut and less need for post-processing.
Fiber laser cutting machines are also much more precise than CO2 lasers, with the ability to cut very tight corners and intricate patterns. They can also cut at much higher speeds, which leads to increased productivity.
In addition, fiber laser cutting machines require very little maintenance and can operate for long periods of time with little or no downtime.
4.The disadvantages of fiber laser cutting
Fiber laser cutting machine is a kind of laser cutter that uses a fiber laser to output a high-energy-density laser beam, which is focused on the surface of the object to be processed. The area where the focus spot forms the melt, vaporization or ablation plasm. The moving direction of the beam relative to the material generally defines the size of the processing zone. And because of its own processing advantages, fiber laser cutting machine has been favored by many manufacturers.
The disadvantages of fiber laser cutting are as follows:
1.The cost of fiber lasers is still relatively high;
2.Fiber lasers cannot process reflective materials such as copper and aluminum;
3.The wavelength of fiber lasers is fixed and cannot be changed.
5.How to choose a fiber laser cutting machine
Different materials require different laser powers and therefore different machine types. In order to make the right choice of machine, it is important to know the following three things:
-The type of material you want to cut
-The thickness of that material
-The desired level of precision
Once you know those three things, you can begin to narrow down your options and find the right machine for your needs.
6.How to operate a fiber laser cutting machine
Operating a fiber laser cutting machine is not difficult, but there are some important safety considerations that must be observed. Always wear appropriate safety gear, including gloves, goggles, and a respirator. If you are working with dangerous materials, such as asbestos or lead, be sure to follow all safety precautions.
To operate the machine, start by loading the material onto the cutting bed. Make sure that the material is secured firmly in place before starting the laser. Once the material is in place, select the desired settings on the control panel. These settings will determine the size, shape, and depth of the cut.
When you are ready to start cutting, press the button on the control panel to activate the laser. The laser will begin moving automatically along the cutting path. You can guide the laser manually if desired, but it is not necessary. The machine will automatically stop when it reaches the end of the cutting path.
Once the cutting is complete, turn off the machine and unload the material. If necessary, you can use a handheld vacuum to clean up any debris left behind by the laser.
7.How to maintain a fiber laser cutting machine
You should check the water in the chiller every day to make sure it is full and the cooling fins are not blocked with dust. Also, be sure that the air compressor has the proper amount of lubricant. The guideline is to change the oil every two years or 4,000 hours, whichever comes first.
8.Troubleshooting for fiber laser cutting machines
8.1. Abnormal light spot 8.1.1 Description The center of light spot is not round enough, or has double light spots, or has a very large light spot. 8.1.2 Solutions: Adjust the parameters of X and Y axis； Re- focus; Check and clean the lens and collimating mirror; Check whether there is any misalignment for the reflector in the resonator; For double light spot, it may be caused by bad Q switch, please check and change the Q switch; For large light spot, it may be caused by bad focus lens, please check and change the lens.
