1.What is a fiber laser cutter?

  Fiber laser cutter is a CNC laser cutting system for metal, which is with high cutting quality, high cutting speed, high cutting precision and high cutting efficiency. It is suitable for most of of metal cutting and the fiber laser cutting machine is your good partner in metal processing. Equipped with different power (from 1,000W to 30,000w), it is used to cut metal materials with different thickness, such as stainless steel, carbon steel, electrical steel, galvanized steel, aluminum zinc plate, aluminum, aluminum alloy, titanium alloy, copper, brass, iron, etc. Fiber laser cutting machine is also called fiber laser metal cutting machine, fiber laser cutting machine, fiber laser cutting system, fiber laser cutting equipment, metal laser cutting machine, fiber optic laser cutter, laser metal cutter, laser cutter machine for metal, CNC laser cutter, CNC laser cutting machine, cnc laser metal cutter, fiber optic laser cutting machine.

2.What is a fiber laser generator?

The Fiber laser generator is used in the fiber optic laser cutter, and it a laser generator with rare earth doped glass fiber as gain medium. The pump light of the fiber optic laser generator is used to irradiate the glass fiber pump source doped with rare earth elements, which stimulates the absorption of photons by rare earth ions. The excitation radiation is the same as the incident photon frequency, and the propagation direction coherent light and vibration direction are amplified by light to generate high-energy laser.

Fiber laser generator has a wide range of applications, such as the material processing, medical beauty, communication, instruments and sensors, scientific research and military, etc. The largest field of fiber optic laser application, material processing has developed many application technologies such as laser cutting marking, welding, cleaning and surface treatment, and cladding.

Fiber laser cutting industry has become the most widely used field for fiber laser technology. Because the working medium of optical fiber laser generator is optical fiber, its characteristics are affected by the transition characteristics of optical fiber. The fiber laser pump light entering the optical fiber generally has a variety of modes, and the signal photoelectric may have a variety of modes. Different fiber laser pump modes have different effects on different signal modes, which makes the analysis of fiber laser generator and amplifier more complex. The doping distribution in the optical fiber also has a great influence on the fiber laser generator. In order to make the medium have gain characteristics, working ions (i.e. impurities) are doped into the optical fiber laser.

Generally, the working ions are evenly distributed in the core. However, the distribution of different modes of pump light in the fiber is uneven. In order to improve the pumping efficiency of the fiber laser, the ion distribution and pumping energy distribution should be as close as possible. When analyzing the optical fiber laser generator, in addition to the general principle of the laser generator discussed above, we should also consider its own characteristics, introduce different models and adopt special analysis methods to achieve good analysis results.

Like the traditional solid and gas laser generator, the fiber laser generator is also composed of three basic components: pump source, gain medium and resonator. The pump source of the fiber optic laser generally adopts high-power semiconductor laser generator, and the gain medium is rare earth doped fiber or ordinary nonlinear fiber. The resonator can be composed of various linear resonators such as fiber grating and optical feedback element, or various linear resonators can be composed of couplers. An annular cavity.

The pump light of the fiber optic laser is coupled to the gain fiber through an appropriate optical system. After absorbing the pump light, the gain fiber forms particle number inversion or nonlinear gain to produce spontaneous emission. The generated spontaneous emission light forms a stable laser output through the excitation amplification and mode selection of the resonator.

3.How does the fiber laser cutting machine work?

Through the numerical control system, the optical fiber laser cutting machine is with an optical fiber laser generator, which dopes the pump material into the optical fiber and couples the laser of specific wavelength emitted by the semiconductor laser to make the optical fiber produce laser. And then, the optical fiber laser cutter converges the laser beam into a small-diameter spot to form a high-energy density and extremely bright beam, which will act on the cut metal to make the metal temperature at the laser irradiation point rise sharply and reach the vaporization temperature instantly, causing evaporation and forming holes. The laser cutting machine takes this as the starting point and makes the fiber laser beam move relative to the workpiece according to a certain trajectory according to the shape requirements of the workpiece to be cut to form a slit. At the same time, the auxiliary blowing device is used for slag removal.

9.How to maintain the fiber laser cutting machine?

How to use and maintain metal laser cutting machine? Is it easy to do it? When using metal laser cutting machine to do engineering, the operator should learn the skills of use and maintenance the metal laser cutting machine, so as to give better play to the effectiveness of the equipment and maximize the efficiency of the metal laser cutting machine.
1. Check the steel strip frequently to ensure the tension of the metal laser cutting machine. Otherwise, if problems occur during operation, personal injury or even serious death may be caused.
2. Check the straightness of the track and the verticality of the machine every half a year, and repair and debug in time if any abnormality is found. Without doing this, the cutting effect may be bad, and the error will happen, which will affects the cutting quality. This is the first task and must be completed.
3. Vacuum the dust and dirt in the machine once a week. All electrical cabinets and main parts of the metal laser cutting machine shall be sealed and dustproof.
4.The guide rail of the metal laser cutting machine shall be cleaned frequently to remove dust and other sundries, so as to ensure that the metal laser cutting machine frame is cleaned frequently and lubricated without sundries. The guide rail of the metal laser cutting machine should be cleaned and lubricated frequently, and the motor of the metal laser cutting machine should also be cleaned and lubricated frequently. The fiber laser cutting machine can move better and cut more accurately in the cutting process, and the quality of cutting products will be improved.
5.Double focal length laser cutting head is a fragile product on laser cutting machine. Long term use will damage the laser cutting head.
The fiber laser cutting machine needs regular inspection and maintenance. If there is deformation or other forms, you should know that the laser cutting head has been damaged a little, and you need to replace it. Non replacement will affect the cutting quality and increase the cost. Some products may need to be reprocessed and reduce the production efficiency.

10.What should we pay attention to when using fiber laser cutting machine?

1. Ensure that the power socket is in good connection and the ground wire of the fiber optic laser cutter is reliably grounded.
2. Ensure that the working voltage of the fiber optic laser cutter ’s chiller is stable and normal.
3. Mismatched power frequency will cause damage to the fiber optic laser cutter . According to the actual situation in your country, please choose 50Hz or 60Hz.
4. In order to protect the circulating water pump, it is strictly prohibited to operate the fiber optic laser cutter without water. Empty the water storage tank before packing the new machine. Please make sure that the water tank is filled with water before starting up, otherwise it is easy to damage the water pump. When the water level of the water chiller’s water tank is lower than the green (normal) range of the water level gauge, the cooling capacity of the chiller will decrease slightly. Please ensure that the water level of the water tank is within the green (normal) range of the water level gauge. Do not use circulating pump for drainage.

5. Ensure that the air inlet and outlet channels of the chiller are unblocked. The air outlet above the chiller of the fiber optic laser cutter shall be Min.1250px away from the obstacle, and the side air inlet shall be Min. 500px away from the obstacle.
