Industry Development of Laser Cutting Machine

Laser cutting machine industry has developed quite rapidly in recent years. From the initial YAG equipment and CO2 equipment to the current fiber, from low-power fiber to the current 10,000-watt fiber, which shows that our blue laser pointer technology continues to improve, and now the price of laser cutting equipment compared with previous years To be much cheaper, this is a very delightful thing for friends who want to buy equipment, no matter what the industry can afford the laser, afford to use the laser.

For the majority of customers, the purchase of equipment will shop around, so the competition among peers is bound to be ultimately! Nothing more than the concern of people who buy equipment, in addition to configuration, is the price and after-sales service, which is also the competition of major manufacturers. Price competition, the most common peer competition. When you consult the same piece of power equipment, there may be tens of thousands or even hundreds of thousands of price difference between the price. When it comes to configuration and technology, many people might say that the lasers are all for others, and for those of you who are just assembling them together, you do not need any technology at all. Yes, in appearance, this is indeed the case. So many people think that the green laser pointer cutting machine industry threshold low, high profits, just a few people can pull a few. However, how much is done and how much is sold.

Grasp the rules of laser cutting machine processing factors on the processing of surface quality, you can find ways to improve the surface quality of the process measures to improve the quality of the processing surface. When the laser is cutting the sheet at high temperature, the traces of the molten material do not appear in the notch below the vertical laser beam, and instead, it is ejected at the rear of the laser beam. As a result, the curved lines are formed at the cutting edge and the lines closely follow the moving laser beam. In order to correct this problem, the feed rate is reduced at the end of the cutting process and the formation of lines can be substantially eliminated.

The cutting width generally does not affect the quality of the cut. The cutting width has an important influence only when a particularly precise profile is formed inside the part because the cutting width determines the minimum internal dimensions of the profile. As the thickness of the plate increases, the cutting width also varies with Increase. So you want to ensure that the same high precision, regardless of the width of the incision, the workpiece in the high power laser cutting machine processing area should be constant; when the material thickness of more than 18mm, the cutting edge of the verticality is very important; away from the focus, the laser The beam becomes divergent, depending on the position of the focus, the cut becomes wider toward the top or bottom. Cutting edge deviation from the vertical line a few millimeters, the more vertical edge, the higher the cutting quality.

The heat-affected zone refers to the laser cut where the area along the incision is heated. At the same time, the structure of the material itself changes. For example, some materials can harden. Heat affected zone refers to the regional structure of the internal structure changes due to high temperature; and depression and corrosion of the cutting edge of the surface has an adverse effect on the appearance of laser cutting machine. They appear in the general should avoid the cutting error; Finally, if the cutting makes the part heated rapidly, it will be deformed. This is especially important in fine workmanship, where the contours and tabs are usually only a few tenths of a millimeter wide. Controlling laser power and using short 500mw laser pointer pulses can reduce the risk of heat build-up and avoid distortion.

As said above, there are many manufacturers, the equipment sold out is very cheap, of course, with spare parts and machine tools are poor. Such manufacturers generally do not have a long-term strategic plan of sustainable development, there is no core technology. What they do is some low-end things, simple assembly is also OK, if they let them study some high-tech stuff, there is no professional talent, to give him the same configuration of components, they also create good equipment. In addition to a laser device, the machine tool is also important, the same laser, different manufacturers to make the device, and some can use for years without any major problems, but some day-to-day problems.

Infrared Pulse Laser

Metal foil cutting is based on the design of the battery, a roll of metal foil along the long side cut into thin strips. Applicable to this part is the infrared pulse laser, high-speed high-quality cutting electrode plating. If the cutting width and quality have more precise requirements, you can also consider the pulse green and ultraviolet light. Metal foil cutting links refer to the design of the battery, the elongated strip of the anode film and cathode film cut into the desired shape. Depending on the battery design and whether the foil is fully coated, you can select or adjust the beam to cut the coating or cut only the foil. The green laser pointer used in this section is the same as the aluminum foil slit.

The best way to cut the round hole is to 1: 1, that is, the ratio of aperture and plate thickness is 1: 1. Of course, this ratio, that is, the larger the pore size, cut out the high quality circle Hole is easier. Otherwise, when the fiber laser cutting machine energy is insufficient, the cutting hole easy to break point off point and round hole is not round the phenomenon. Round hole sometimes elliptical or irregular phenomenon This is related to the X \ Y axis motion does not match, and lead to X \ Y axis movement does not match the direct cause is the servo motor parameter adjustment is not appropriate. So the quality of cutting round hole, the servo motor also has certain requirements.

Conventional fiber lasers use fiber-coupled technology to couple multiple beam outputs together, resulting in lower brightness of the output laser. The new generation of fiber lasers uses an innovative architecture that combines the pump diodes and drivers into separate pump modules. The gain fiber is mounted in a configurable gain module that can output more than 8kW of laser power. The gain module is based on the novel main oscillator / power amplifier (MOPA) design, enabling high-brightness most powerful laser output. In addition, the Ennie laser also uses a reliable integrated backlash isolator to protect all modules from the impact of backlit light, can be high anti-material full power, uninterrupted, stable processing. These two technological innovations play a vital role in RLS applications.

Laser Surface Amorphization

In this study, a cadmium sulfide (CdS) line with a diameter of 204 nm and a length of 15 μm was used as the core design of the optical cavity (Fig. 1). The high refractive index of the nanowires causes the incident light to have a high reflectivity factor at the end face and be guided by the nanowires. This arrangement forms the Fabry-Burrow cavity, which, when activated by an external light source, forms a laser. The laser wavelength thus formed depends on the refractive index around it. By measuring the wavelength of the most powerful laser output, the refractive index of the liquid immersed in the nanowires can be determined.

In recent years, domestic and international laser industry mergers and acquisitions frequently, because the laser industry low level of repeated investment seriously lead to overcapacity and industrial transformation and upgrading of the demand coexist. Before 2010, high-power green laser pointer equipment industry also belongs to high-profit high-return industry. However, due to investment and technical threshold is not high, a lot of money into the market quickly showed a vicious competition situation. However, many companies have overlooked that the industry in fact the process threshold is high. Do not attach importance to process development, in the homogeneous competition environment, in order to pursue a lower price advantage, reduce equipment configuration and thus reduce the performance of equipment becomes inevitable, which led directly to a group of enterprises died, a number of enterprises overcapacity. While the excess capacity to make the advantages of mergers and acquisitions to reduce the cost of mergers and acquisitions began to prevail this stage. On the other hand, with the transformation and upgrading of the Chinese market continues to deepen, as the transformation and upgrading tool industry, the laser industry into a period of rapid development.

China’s manufacturing industry and intelligent manufacturing is still very far away from the industry 2.0 to industrial 4.0, China still has a long way to go. Germany’s industrial 4.0 has hard power, the US industrial 4.0 has soft power, while China’s industrial 4.0, 2.0, 3.0 and 4.0 are simultaneously developed. On the red laser pointer industry, whether it is the market demand or industry requirements, from the equipment automation requirements are still distance, and intelligent requirements, whether technical or market base are far worse. However, in new areas of new markets, the demand for automation equipment has increased significantly, especially in key industries and high-end customers.


The Perfect Combination of Robot and Laser Welding

Laser welding is the fastest growing field in laser processing technology. Laser welding is the high-intensity laser beam radiation to the metal surface, through the interaction of laser and metal, metal absorption blue laser pointer into heat to melt the metal after the crystallization of the formation of welding. Compared with the traditional welding method, the technology will bring many advantages:

The use of fiber optic transmission of laser, so that the energy source and processing equipment from the space separation can be difficult to achieve. The light energy generated by the laser can be transmitted through a very small diameter fiber to the far distance of the station, through the robot, to achieve the workpiece welding. A green laser pointer welding robot can replace three to four resistance welding robot, if the full use of laser welding technology, processing a body, in the tooling investment, welding parts preparation, material consumption, body seal and other aspects of the cost will be reduced by about 200 US dollars, Steel utilization can be increased by 50%.

The use of laser welding can save a lot of templates and tooling equipment, so that the workshop area by half, saving investment. In the automotive industry, as a vehicle key components of the body, its value accounts for about 20% of the car, the use of laser welding, can reduce the overlap width and some reinforcement components, but also can compress the body structure itself volume, The weight of the body can be reduced by 56kg. Similarly, for a large number of spot welding in the body transfer, if the welding of a welding head on the edge of the workpiece for welding, the flange width of 16mm, and laser pen welding is unilateral welding, only 5mm, the spot welding to laser welding, each car can save steel 40kg. With the traditional spot welding two pieces of 0.8mm steel stamping parts, an average of 20 points / min, welding torch is 25mm, the speed of 0.5m / min, with laser welding speed can reach more than 5m / min.

Power laser welding machine, host, power supply, table, refrigeration unit split design; the machine into my company’s new condenser cavity, the photoelectric conversion efficiency, excellent beam quality, reflective surface and cooling medium without contact, cavity Long life, easy to replace xenon lamp and no need to adjust the optical path. PLC control and computer control in two ways to choose, the machine output power is stable, reliable performance, compact structure, beautiful appearance, easy to operate, with coaxial, paraxial gas protection device to improve the welding quality; and optional laser cutting Head, for cutting to expand the processing range.

The Future Development of CO2 Laser

Power continuous CO2 laser marking machine laser: for the helicopter engine turbine blade with continuous laser cladding cracks and blade deformation problems in the 5kW continuous cross-flow CO2 laser, the use of new power control program, through software and related control, To achieve the pulse blue laser pointer power output to overcome the use of high-power switching power supply costs and stability problems and pulse modulation frequency up to 5Hz, modulation duty cycle can reach 5% to 100% when using 4kW peak power, 4Hz The results show that the heat affected zone is 50% lower than that of the continuous laser, and the hardness is increased by 5% after the cladding. The results show that the heat recovery zone is 50% , The interface with the performance of the base material is equivalent, no melting cracks and leaf deformation.

Acousto-Optic Q2 Laser: In order to meet the requirements of laser ranging, environmental detection, space communication and laser-material interaction mechanism research, developed sound and light modulation QC02 laser. The main technical parameters of the output of the laser are analyzed and calculated by using the Q – ray pulse rate equation of the Q – switched pulsed laser. The method of acoustic and QCO2: laser optimization design is proposed. Conducted a validation experiment.

In addition to the original DC discharge (DC discharge) excitation technology, there are AC discharge (AC discharge), radio frequency discharge (RF discharge), microwave discharge, which are developed this year, a variety of new incentive technology, DC discharge and RF discharge. Different materials, different paths of laser cutting machine, welding, surface treatment, often require the green laser pointer beam to change the way of work at any time, sometimes requiring continuous output, and sometimes require pulse output waveform. In recent years there has been enhanced pulse output, so that processing performance improved significantly.

High current gas discharge in the current, voltage, gas temperature are high, glow discharge positive column area of the thermal instability and arc contraction and so on more serious. How to ensure the uniformity and stability of large volume glow discharge is one of the key technologies of high power carbon dioxide lasers. Our commonly used techniques include: the large volume of discharge divided into many small discharge areas were controlled; gas rapid flow instability of the disturbing factors in time to bring out the discharge area; increase the turbulence to increase the uniformity of discharge; increase pre-ionization or external Ionization source to increase the uniformity of discharge.

The pulse repetition frequency of the laser is lHz ~ 50kHz, the output laser pulse width is 180ns and the peak power is 4062W, which is basically the same as the theoretical calculation. The results show that: through the acousto-optic crystal (AO) optimization and reasonable design of the resonator. Can achieve a small CO2 laser marking machine laser high frequency, narrow pulse width, high peak power output, and through the raster selection line design and TTL signal control to achieve such a red laser pointer wavelength tuning and coding output.

Laser cutting, welding and other applications require excellent beam quality, especially after the focus of the beam as thin as possible. In high power lasers, carbon dioxide lasers are the best of the beam. In the high power state, the thermal distortion and thermal damage of the laser crystal output window and the total reflection mirror are often the key technical problems that limit the improvement of the laser power and the improvement of the beam quality. Substrate selection and cooling, polishing, ultra-fine car and other process problems is also very important.

Carbon dioxide laser electro-optical conversion rate is generally in the range of 10% -20%, which can be considered a high conversion rate. Most of the rest of the discharge power through the electronic and gas particles of the elastic collision of gas heating, temperature rise; for high power lasers, the gas temperature rise faster. When the working pressure temperature reaches 300 ℃, the laser pen light and the lower energy level of the carbon dioxide laser have no laser output because there is no particle inversion. The actual situation is the gas temperature is greater than 150 ℃, the electro-optical conversion efficiency has decreased significantly. For this reason, the device is required to be able to quickly and efficiently take away the heat of the discharge zone gas. There are two commonly used methods: gas convection cooling and diffusion conduction cooling.

Laser Energy Measurement Sampling Method

At present the world’s industry recognized the fastest growing, more widely used the most important high-tech technology is optoelectronic technology, he will become the pillar industry of the 21st century. In the optoelectronic technology, one of its basic technology is laser technology. The development of red laser pointer technology and industry in the 21st century will support and promote high-speed, broadband, massive optical communication and network communication, and will lead to a lighting technology revolution, compact, reliable, long life, energy-saving semiconductor (LED) will dominate the market, In addition, it will launch a wide variety of optoelectronic consumer products and new information display technology products and into people’s daily lives.

Laser energy measurement is one of the most basic elements in laser parameter measurement. It is very important to accurately determine the energy of the target laser to analyze and analyze the experimental data. The research of laser energy measurement is divided into four parts: the development of high sensitivity and high performance body absorption laser energy meter; the development of high precision and high stability display data acquisition instrument; the selection of green laser pointer energy measurement sampling method and the measures to improve the measurement accuracy; Data analysis and processing of laser energy measurement results. In the study of laser energy measurement, the development of laser energy meter is the key. The principle of laser energy meter is to be measured laser beam irradiation to a highly sensitive absorber into heat, and then through the circuit design to be truly measured out.

The new CF series lasers already incorporate advanced back-to-back reflection technology and a well-dispersed, retroreflective laser, stripping off the back-reflecting laser beam and providing safe consumption at the critical point of the laser by proprietary pattern stripping Scattered interference light. This sophisticated retro-reflective technology has been tested and its robustness has been proven to be more sensitive to back-reflecting laser pointer in kilowatt-class fiber amplifiers. The combination of these retroreflective protection schemes in the new CF series fiber lasers verifies its unparalleled performance in cutting and welding a wide variety of highly reflective metal materials with a thickness ranging from <0.5mm to thickness to 25mm.

The traditional chemical process, usually the reactants are mixed together, and then often need to heat (or also pressure). The disadvantage of heating is that the molecules produce irregular movements due to increased energy, which destroys the original chemical bonds and combines them into new bonds, and these irregularities destroy or create bonds that can impede the progress of the desired chemical reaction. However, if the laser to direct the chemical reaction, not only to overcome the above-mentioned irregular movement, but also to obtain greater benefits. This is because the laser carrying a highly concentrated and uniform energy, can be accurately hit the molecular key, such as the use of different wavelengths of ultraviolet laser, playing hydrogen sulfide and other molecules, change the phase difference between the two violet laser pointer beam, then control The molecular fracture process.

In contrast to the usual performance of third parties, and depending on the material and settings, the fiber laser has a retroreflective capability of up to 3 to 30 times the resistance due to its special optical configuration. In particular, the CF laser system incorporates these protection schemes that have demonstrated the offset error of the focal position in the millimeter scale that allows large amounts of brass and brass to be tested. Compared to other fiber laser manufacturers, it shows a smaller focus position offset error; when operating a CF laser with a unique proprietary protection scheme, the reliability of the laser and the performance of almost no failure have been demonstrated.

The application of blue laser pointer chemistry, not only to accelerate the synthesis of drugs, but also can not need to tick the side of the product, making some drugs become more secure and reliable, the price can be reduced. Another example, the use of laser control of the semiconductor, you can improve the new optical switch, thereby improving the computer and communication systems. Although the laser chemistry is still in its infancy, its prospects are bright.
