The Advantages of Fiber Laser Cutting Machine

Under the unfavorable market environment of low price competition, a large number of domestic manufacturers and brands do not stand out, the relative lack of technological innovation, dependence on advanced foreign technologies and lack of core competitiveness. At the same time, rising labor costs, coupled with rising raw materials, have also increased the cost pressures of many enterprises. It can be predicted from the above phenomenon, intensive mode of development will be a lot of blue laser pointer pen cutting machine business in the future direction.

Laser cutting machine companies need to come out from the price competition, turn to practice internal strength. Focus on product structure optimization, product quality improvement, core technology mastery and innovation, as well as the expansion of corporate brand influence. Of course, this series of changes require companies to invest more capital, this, laser cutting machine companies also need according to their own circumstances, the future of the input-output ratio to make a scientific estimate, so that selective investment, the gradual transition.

The working principle of the fiber laser cutting machine is that the laser is used to generate the laser, the laser is then transmitted to the cutting head through the optical path, and then the focus is achieved. The unit energy of the focused unit is high, and the high energy density focuses on the metal to be cut Surface, resulting in very high temperatures, the moment the metal melts, and use the auxiliary gas blowing off the slag, the formation of cutting seam, to cut the purpose. Fiber high powered laser pointer cutting machine with high precision, cutting fast, not limited to the cutting pattern restrictions, automatic layout to save material, cutting smooth, low processing costs, will gradually improve or replace the traditional metal cutting process equipment. Fiber, YAG and CO2 laser cutting machine principle is similar. What they are different is the size of the laser is not the same, the key configuration is different. It is precisely because of these differences determine the laser cutting machine processing capacity and value.

green laser light

With the development of industrialization, the demand for thin plate in the future market is increasing, and the demand for fiber laser cutting machine will be more and more big in all walks of life. At the same time, the market demand for this kind of machinery will continue to improve. Any product is compared to have the effect, the effect of fiber laser cutting machine in many people seem to be much better than ordinary mechanical cutting machine, this comparison is not only the choice of human progress, but also social progress for the promotion of modern industry.

Advantages of fiber laser cutting machine: high cutting accuracy, laser cutting machine positioning accuracy 0.05mm, repeat positioning accuracy 0.03mm. The cutting seam of laser cutting machine is narrow, and the green laser light beam is focused into small light spots, which makes the focus reach a very high power density. The material is heated to the degree of gasification quickly and evaporated to form holes. With the relative linear movement between the beam and the material, a slit with narrow width is formed continuously, and the kerf width is generally 0.10-0.20mm. The cutting surface of the laser cutting machine is smooth, the cutting surface has no burr, and the roughness of the incision surface is generally controlled within Ra6.5. Laser cutting machine speed, cutting speed of 10m/min, the maximum positioning speed of 30m/min, much faster than wire cutting.

Good cutting quality of laser cutting machine, non-contact cutting, cutting edge heating effect is very small, basically no thermal deformation of workpiece, completely avoid the formation of material punching when cutting edge collapse, generally do not need two processing. Without damaging the workpiece, the laser cutting head will not contact with the material surface, so as to ensure that the workpiece is not scratched. Not affected by the shape of the workpiece, laser processing flexibility is good, can be processed arbitrary graphics, cutting pipe and other special-shaped materials. Laser cutting machine can cut a variety of materials, such as plastics, wood, PVC leather, textiles, plexiglass and so on. The mold investment is saved, the laser 303 processing needs no mould, no die consumption, no need to repair the mould, save the replacement mould time, thus saving the processing cost and reducing the production cost, especially suitable for the processing of large products.

Laser Communication and Imaging

Laser communication is wireless connections through the atmosphere. It is now able to send information at data rates up to several Gbps and at a distance of thousands of kilometers apart.

The information is sent to the light modulator which is connected with blue laser. The modulator processes the information on a laser by adjusting amplitude, frequency or phase. Then the information is transmitted by optical antenna. At the receiving end, the oscillator and signal are mixed and then transformed into the original information by the photoelectric balance detector and loop filter, after amplification and demodulation.

Laser communication has the advantages of small transmission loss, long transmission distance, high communication quality, large communication capacity, strong confidentiality and light structure. It is mainly used for ground communication, global communication and interstellar communication.

Laser imaging: Illuminate the target with the three frequency shift laser beam to produce the moving interference fringes on the surface, then receive the echo with energy detector and demodulate echo to get the the Fourier amplitude and phase spectrum of target on the surface. Finally, eliminate the atmospheric jitter by closure phase and reconstruct the target image by the Fourier inversion.

Our precision manufactured lasers and laser pointer systems deliver the highest possible laser graphic imaging performance on a wide variety of materials, including marble, wood, glass, plastics, painted metals, textiles, anodized aluminum and more. The imaging system has the advantages of high resolution and ultra long range imaging. It can also overcome the atmospheric turbulence.

Laser Application Technology

Laser refers to the product of stimulated emission light amplification, it has a monochrome, collimation, coherence and high energy density and other characteristics. It is because of the superior characteristics of laser, people will be widely used in human life in all aspects, such as printing, welding, cutting, communication, storage, etc., can be said that the blue laser for human production and life brought a qualitative leap. However, at the same time, the laser has also brought a lot of security to the human problem.

Metal marking machine is mainly used in laser marking processing, but the laser marking a wide range of metal materials can be marked processing is usually selected fiber laser matching marking equipment, such as carbon dioxide laser marking device is Can not be processed on the metal marking, the reason why there will be such a reason, with its own wavelength and its own characteristics of the decision. Fiber lasers due to the use of optical fiber transmission, and industrial machinery control flexible integration of higher, free from space or location factors, more able to achieve semi-automatic, automated, intelligent direction, the expansion of space is greater, while fiber green laser pointer almost No maintenance, power stability, good beam quality, long-term application cost-effective, easy to use, no need to replace any other accessories.

Static laser energy spectrum is a stable spatial distribution. Mainly applicable to micron-scale particles of the test, after the improvement can also be extended to tens of nanometers measurement. The dynamic laser analyzes the size of the nanoparticles by detecting the dynamic light scattering signals of one or two scattering angles according to the speed of the grain Brownian motion, and the energy spectrum changes with time. The dynamic light scattering principle of the particle size analyzer is only applicable to nano-scale particles. Transparent settlement usually refers to the laser particle size analyzer refers to the principle of diffraction and scattering particle size analyzer, light through the settlement instrument, based on the principle of Stokes settlement law rather than high power laser diffraction / scattering principle, so this instrument can not be called Laser particle size analyzer.

With the rapid development of laser application technology, many of the traditional manufacturing industry, the introduction of laser technology for products for enterprises to bring technological innovation and new impetus, but many companies do not do laser product safety certification preparation, for laser Of the hazards, the level of laser safety, the evaluation criteria and the national market for laser safety requirements are relatively unfamiliar. Mainly in the following areas: R & D design, production and processing personnel do not have the experience of laser work; corporate norms did not establish a sound laser safety requirements; personnel and facilities of laser safety protection is not in place.

red laser pointer

The application of the laser in the client often requires the combination of laser shield, fiber, robot, exhaust and other ancillary equipment to form a complex red laser pointer processing production system. The systematic safety assessment of these laser processing systems is often overlooked by the enterprise. Compared to the safety requirements of a single laser device, the safety assessment of the laser processing system is much more complex: not only requires the laser light source to be designed to meet laser safety requirements, but also to require all parts of the system to work together to prevent all possible hazards ; Not only to consider the laser beam-related hazards, but also to consider electrical hazards, mechanical hazards, chemical hazards, ionizing radiation hazards, toxic and hazardous substances hazards.

The person in charge of laser safety refers to the personnel designated by the enterprise who have sufficient knowledge of laser safety and can assess and control the laser hazard for the enterprise. The person in charge of laser safety needs to be involved in all activities that may cause laser hazards, and to manage the laser pen safety issues within the enterprise. Enterprises need to introduce the laser safety in the management system and organizational structure, giving the laser safety responsible person full power, the formation of internal focus on laser safety system.

The Technical Disadvantage of Laser Cutting

During the Cold War broke out in the last century, both the United States and the Soviet Union attached great importance to the actual development of laser weapons and accelerated the development of laser weapons. In 1983, the US Reagan administration proposed the "Star Wars" program, highlighting the superpower will be used in the national military weapons and equipment aspirations and ambitions, the purpose is through the deployment of large-scale green laser pointers weapons in the space on the enemy's satellites, missiles , Ships and even the implementation of precision strike on the ground fortress, which has become a follow-up science fiction film numerous times the classic plot.

red laser

Laser weapons are new concept weapons that use high-energy beams instead of conventional chemical warheads for physical and electrical damage. It is a directional energy weapon that directs a long-range target by a high-energy laser beam emitted in a certain direction. It consists mainly of a laser that generates a light source and a beam director with tracking, aiming and firing, and is damaged by heating, radiation, etc. Way to attack the target. In laser machining, blue laser pointer light emitted from the laser collimation and focusing lens by the sink of the cutting head to a point (focus), operators need to ensure that the laser beam machining in the nozzle is the center, and adjust the distance from nozzle plate surface (as the plate thickness and spray nozzle), high pressure gas, and with the completion of the laser beam cutting operation.

Laser weapons in accordance with the use of combat can be divided into tactical laser and strategic laser two. Tactical laser is used for photoelectric confrontation and tactical air defense of the laser weapons, can instantly blind enemy officers and soldiers of the eyes and destruction of photoelectric sensors to paralyze combat equipment, can also burn directly through the enemy tanks, aircraft, unmanned aerial vehicles, missiles and other important Military target. The strategic red laser pointer is used to attack strategic missiles and in orbit satellite laser weapons, through the ground or space orbit deployment, can destroy the enemy satellites in wartime in order to obtain the system of natural rights, and the implementation of enemy ballistic missile defense.

This is related to the specific process parameters, material type and beam quality. Deformation: as the laser cutting is essentially thermal cutting, the plate inevitably exists deformation, and the excellent cutting should minimize the adverse effects as much as possible. Particular attention should be paid to the cutting of thin plates. In general, the cutting speed is faster, more narrow, cutting gas flow increases, the deformation of the smaller. In the market of laser processing equipment, laser cutting is one of the most important application of laser cutting machine, cutting machine, punch substitution effect has become more and more obvious, the market is more popular following the laser marking applications, is expected to cut high-end high power laser speed, high precision, and large format cutting thick plate for the characteristics of the cutting machine equipment market has a larger growth space.

Generally speaking, the thinner the material thickness is, the lower the roughness of the cutting surface is; the lower the surface roughness is when cutting with nitrogen or argon than the oxygen. In addition, it is also related to the relative position of the machining time spot and the material thickness direction. Although the strategic laser weapons have a great use of the prospects, can completely change the traditional strategic deterrence model and break the existing strategic balance, but because of the need for a lot of energy as a basis, and human energy storage equipment miniaturization and micro-nuclear power generation and other important technologies before the problem is solved, it is still difficult to realize the real use of the actual 200mw green laser military equipment and combat.
