Fiber laser is a type of high-energy beam based on a fiber amplifier that uses glass fiber doped with rare earth ions as the gain medium. The pump light irradiates the rare-earth-doped glass fiber pump source, which induces the rare-earth ions to absorb photons, and the excited radiation has the same frequency as the incident photons. Under the action of pump light, it is easy to form high power density in the fiber, which results population inversion of the laser working substance. When a positive feedback loop (constituting a resonant cavity) is properly added, the laser oscillation output can be formed. These laser cutters have a wide range of applications, including material processing, communications, medical beauty, scientific research and military, instrumentation and sensors. It has been used for cutting, engraving, etching, marking, welding, surface treatment, cleaning, cladding, and some other applications. 

The pump light entering the fiber has multiple modes, and different pump modes have different effects on different signal modes, making the analysis of laser generators and amplifiers more complicated. The doping profile in the fiber also has a great influence on the laser generator. In order to make the medium have gain features, the fiber is doped with working ions (i.e. impurities). The working ions are uniformly distributed, whereas the distribution of the pump light is non-uniform. Therefore, to improve the pumping efficiency, the ion distribution and the pumping energy distribution should be as close as possible.

Fiber laser generators are similar to traditional gas and solid laser generators, which are composed of pump sources, resonators, gain media. The pump light is coupled into the gain fiber through the optical system, and the gain fiber generates spontaneous emission after absorbing the pump light, and outputs stable beam.

How To Laser Cut Metal with CNC Controller?

A laser cutter uses a generator with the CNC control system to dope the pump material into the optical fiber, and the laser of a specific wavelength emitted by the semiconductor laser is coupled to make the optical fiber generate beam. Then, the machine converges the beam into a small diameter spot to form a beam of high energy density and extremely bright light, which acts on the metal to be cut, which causes the temperature of the metal at the irradiation point to be sharp it rises and reaches the vaporization temperature instantaneously, causing evaporation and forming holes. And the machine uses this as the starting point, according to the shape requirements of the part to be cut, the beam and the part are moved relative to each other according to a certain trajectory to form a slit. At the same time, the auxiliary gas blowing device is used to remove the slag.

Pros & Cons

Pros

It is a new type of laser cutting technology in the world that outputs a high-energy density beam and gathers it on the surface of the part to instantly melt and vaporize the area on the part irradiated by the ultra-fine focus spot and move the spot through the CNC controller. Irradiate the position to realize automatic cutting. Compared with the bulky gas and solid laser, it has obvious advantages. It has gradually developed into an important candidate in the fields of high-precision cutting, lidar systems, space technology, medicine and other applications.

It can be used for flatbed cutting and bevel cutting, and the edges are neat and smooth. It is suitable for precision cutting of sheet metals. In addition, the robotic arm can do 3D cutting instead of the 5 axis laser cutter. Compared with CO2 laser cutters, these cutters will save space and gas consumption, and has a high photoelectric conversion rate. It is a new power tool of energy saving and environmental protection, and it is also one of the world's leading technological CNC machine tools.

1. High accuracy: The positioning accuracy is 0.05mm, and the repeated positioning accuracy is 0.03mm.

2. Narrow slit: The beam is focused into a small spot, so that the focus reaches a high power density, the material is rapidly heated to the point of vaporization, and the holes are vaporized. With the relative linear motion of the light beam and the material, the hole continuously forms a narrow slit, and the width of the slit is generally 0.10-0.20mm.

3. Smooth cutting edge: There is no burr on the cutting edge, and the roughness of the cutting surface is generally controlled within Ra6.5.

4. High speed: The cutting speed can reach 10m/min, and the maximum positioning speed can reach 30m/min, which is much faster than other metal cutting tools.

5. High quality: It is a non-contact cutting, which endures little thermal influence, the part basically has no thermal deformation, and completely avoids the slump formed when the material is punched and sheared.

6. Non-destructive cutting: The cutting head does not come into contact with the surface of the substrate, ensuring that the parts are not scratched.

Cons

If you stare at the cutting machine for a long time, it will cause very serious damage to the retina of the eye. All operators must wear goggles. Do not operate and observe with eyes exposed. In the cutting path of the machine, it is necessary to avoid the position of any part of the body, so as not to accidentally cause unnecessary injury.

The impact of dust during cutting on the human body. Using the machine in an unsuitable working environment will have the impact of dust. Working in a dusty environment for a long time will also cause great damage to the lungs and trachea. Improper protection will cause lung and respiratory diseases.

Oxygen is often used in the cutting process, and sparks flying during the cutting process can easily cause fire. Therefore, there should be no inflammable and explosive materials in the working area, and corresponding protective facilities should be provided at the same time.

As far as the material is concerned, the addition of the material itself or the coating on the material will produce components that are harmful to the human body at high temperatures, so it should be noted.

Safety depends on the safety guidance of the manufacturer and whether the protective equipment purchased by the enterprise meets the protective standards. Different types of machines have different degrees of damage to the human body, especially the eyes and skin. The exact grade depends on the operator's manual. First, each device comes with a protective goggle. During the cutting process, do not look at the laser for a long time, and do not look too close without a protective cover to avoid the cutting slag splashing on your body. Now almost all equipment is equipped with a dust removal system, which is basically not affected by smoke and dust. The metamorphic laser gas contains a small amount of carbon monoxide, and the carbon monoxide content is very small and will not cause harm to the human body.

Care & Maintenance

When using these machines to cut projects, it is necessary to learn the use and maintenance skills, in order to better exert the effectiveness of the equipment and maximize the efficiency of the equipment.

1. The conveyor belt needs to be checked frequently to ensure the tension. The conveyor belt may seem like an inconsequential component, but the danger posed by it cannot be ignored. Mistakes during operation may result in personal injury or even death.

2. Check the straightness of the track and the verticality of the machine every six months, and find that it is abnormal and timely maintenance and debugging. Without this, the effect of cutting may not be very good, the error will increase, affecting the cutting quality. This is the top priority and must be done.

3. Use a vacuum cleaner to suck off the dust and dirt in the machine once a week. All electrical cabinets should be closed and dustproof.

4. The guide rails should be cleaned frequently to remove dust and other debris, to ensure that the equipment racks are cleaned frequently, and lubricating oil is added to ensure lubrication without debris. The guide rail should be cleaned and lubricated frequently, and the motor should also be cleaned and lubricated frequently, the machine can move better during cutting, cut more accurately, and the quality of the cut product will improve.

5. If any damage is found in the process of using the machine, it must be replaced in time, which is not only a type of protection for the machine itself, but also ensures that the machine always maintains an ideal cutting effect.

A fiber laser cutter needs regular inspection and maintenance. If there is deformation or other forms, you should know that the cutting head has been damaged a little at this time, and you need to replace it. Failure to replace will affect the cutting quality and increase the cost, and some products may need to be reprocessed to reduce production efficiency.

Caution

1. Make the power socket in good contact and the ground wire well grounded.

2. Make the voltage of the water chiller stable.

Since the refrigeration compressor is sensitive to the power supply voltage, the standard working voltage is 200 ~ 250V (100 ~ 130V for 110V models). If you really need a wider operating voltage range, you can customize it separately.

3.The mismatch of power frequency will cause damage to the machine.

Please use 50Hz or 60Hz models according to the actual situation.

4. To protect the circulating water pump, running without water is strictly prohibited.

Before packing a new machine, the water tank must be emptied. Please make sure that the water tank is full of water before starting the machine, otherwise the water pump will be easily damaged. When the water level of the water tank is lower than the minimum requirement of the water level gauge, the cooling capacity of the chiller will drop, and the water level must be within the required range. The use of circulating pump drainage is strictly prohibited.

5. Make sure that the air inlet and outlet channels of the chiller are smooth.

The air outlet above the chiller must be at least 1250px away from the obstacle, and the side air inlet must be at least 500px away from the obstacle.

6.The air inlet filter must be cleaned regularly.

The air filter must be removed and cleaned regularly. Serious blockage of the air filter will cause the chiller to malfunction.

7. Please pay attention to the effect of condensate.

When the water temperature is lower than the ambient temperature and the ambient humidity is high, condensation water will be generated on the surface of the circulating water pipe and the device to be cooled. When the above situation occurs, it is recommended to increase the water temperature or insulate the water pipe and the cooled device.

8. This type of laser machine is an industrial equipment, please do not allow non-professionals to operate.
