I. Introduction
Laser automatic cutting equipment technology is a new development technology with rapid development. Compared with traditional cutting technology such as flame cutting and plasma cutting, it has high processing precision, small thermal deformation, good cutting surface quality and high cutting requirements. It is an ideal cutting and processing technology. The popularization and application of laser automatic cutting equipment will provide advanced technical equipment for the technological transformation of China's traditional industries, the emerging industrial field and the modernization of manufacturing. In the face of the growing huge application market of laser automatic cutting equipment and the new international competition, the industrialization of laser automated cutting technology urgently needs a big development. This situation brings excellent opportunities and challenges to domestic laser-automatic cutting equipment manufacturers.
China's laser automatic cutting equipment technology industry is in a period of rapid development, and some domestic laser cutting equipment and light source technology has reached the international advanced level; until last year, China's laser industry has begun to take shape. As an advanced manufacturing technology, laser technology is increasingly intensive in all walks of life, playing an important role in the transformation and upgrading of China's manufacturing industry. Metalworking Online has reported this many times.
The classification of laser automatic cutting equipment is mainly distinguished by the type of light source, the power of the light source, and the cutting dimension (planar or three-dimensional). The subdivision technical indicators are cutting speed, cutting precision, driving mechanism of the motion mechanism, manual or auto focus function, and work. Table size, etc.
Second, the laser light source and classification techniques Laid
To talk about the technical characteristics of laser automated cutting equipment technology, we must first understand the laser source, because the laser source directly determines other technical performance indicators of laser cutting equipment.
The laser sources of laser automated cutting equipment currently on the market mainly include: 1. CO2 laser 2. Fiber laser 3. The laser working material of the YAG laser CO2 laser is a CO2 mixed gas, and its main application laser wavelength is 10.6 μm. Since the laser has high laser conversion efficiency, and the heat generated by the laser can be quickly transmitted to the laser gain region by convection or diffusion, the average power of the laser output can be achieved at a high level (over 10,000 watts). High power laser processing requirements.
CO2 lasers can be divided into: low power, medium power, high power CO2 lasers:
Low-power (less than 200 watts) CO2 laser applications are mainly used in the electronics industry (such as resistor manufacturing, IC marking), non-metallic processing industry (bamboo wood carving, apparel, footwear, jewelry manufacturing, etc.) and some medical and research units. .
Medium and high power (200W-1600W) CO2 laser application mold industry, cutting of various machine parts, automotive sheet metal cutting, sheet metal cutting of computer and electrical casing, special material cutting such as: plastic, glass, mold, etc. Metal cutting.
High-power (greater than 1600 watts) CO2 laser applications with more than 1600 watts of high-power CO2 lasers, mainly used in metal cutting, welding and surface treatment, have gradually been used in some special fields in the defense, automotive and aerospace industries in advanced industrial countries. Adopted.
Traditional high-power axis fast-flow CO2 lasers are still the mainstream configuration in high-power laser cutting equipment. Although fiber lasers have developed rapidly in recent years, CO2 lasers still account for as much as 65% of the total.
High-power CO2 lasers for laser processing at home and abroad are mainly cross-flow and axial-flow lasers.
The beam quality of cross-flow lasers is not very good, it is multi-mode output, mainly used for heat treatment and welding. At present, China has been able to produce a variety of high-power cross-flow CO2 laser series, which can meet the needs of domestic laser heat treatment and welding.
Axial-flow lasers: Axial-flow lasers have good beam quality and are used for fundamental mode or quasi-basic mode output. They are mainly used for laser cutting and welding. The laser cutting equipment market in China is mainly occupied by foreign axial-flow lasers. Although domestic laser manufacturers have done a lot of work on foreign axial current lasers, because the main parts still need to be imported, the price of the products is difficult to drop drastically and the penetration rate is low.
The swirling CO2 laser uses a novel rotating gas flow mode to make the swirling CO2 laser have the advantages of good axial beam quality of the axial CO2 laser and low cost and small volume of the cross-flow CO2 laser. The promotion and application of this kind of industrial processing laser will play a positive role in promoting the development and popularization of China's laser processing industry.
At the end of the 1960s, China began research on high-power CO2 lasers and their applications. After more than 30 years of hard work, the production capacity of 500W~10kW series products has been formed. About 10 companies and units can produce more than 500W CO2 lasers, including Chutian, Huagong, Dazu, Nanjing Oriental, Nanjing Express. , Shanghai Prima. However, as a whole, there is still a certain distance between Chinese lasers and foreign countries. Most of the Chinese market uses imported products. International brands include: R ofin, Trumpf, PRC, Coherent, Access, Prima, Swiss Super, Mitsubishi, Japan, Mazak, Japan Amada.
In general, China's CO2 laser technology has undergone years of cultivation and has developed to a certain extent. All of the high-power CO2 lasers on most cutting machines in China still rely on imports. Compared with foreign countries, domestic high-power CO2 lasers have a certain gap in terms of their laser quality and their measurement and control systems.
Fiber laser cutting technology has appeared in less than 5 years in China. The superiority of fiber laser is mainly reflected in: fiber laser is a waveguide structure with high gain, high conversion efficiency, low threshold, good output beam quality, narrow line width, structure Simple, high reliability, easy to achieve coupling with fiber, peak output power up to hundreds of kilowatts, near 1.06μm wavelength, high absorption efficiency for most materials, small size, light weight, easy to move, focused spot diameter Small (10~100 μm) enables very precise cutting, eliminating the need for post-processing steps. Through the optical fiber output, it is easy to cooperate with the robot to realize long-distance laser processing. The overall photoelectric conversion efficiency is as high as 25% to 30%, which can work stably for a long time, and is easy to maintain and low in operating cost. More technical articles are available at the Metalworking Online Technology Center.
Although fiber laser cutting is good at cutting most materials, it can't be used to cut acrylic or polycarbonate materials, and only cut wood or fiber materials in limited applications. Fiber lasers are available: SPI, IPG, domestic There is Ruike Laser (owned by Huagong Laser).
The YAG laser output has a wavelength of 1.06 um, which is an order of magnitude smaller than the CO2 laser wavelength of 10.06 μm. Conventional solid-state lasers are typically pumped with high-power gas discharge lamps with pumping efficiencies of about 1% to 3%. The large amount of energy emitted by the pump lamp is converted into heat energy, which not only causes the solid laser to adopt a cumbersome cooling system, but also a large amount of thermal energy causes a thermal lens effect that cannot be eliminated by the working substance, which deteriorates the beam quality. In addition, the life of the pump lamp is about 300 hours. The operator needs to spend a lot of time to change the lamp frequently, interrupt the system work, and greatly reduce the efficiency of the automated production line. However, if a diode-pumped solid-state laser is used, it can be well avoided. at this point.
YAG solid-state laser cutting machine has the characteristics of low price and good stability, but the energy efficiency is generally less than 3%. At present, the output power of the product is mostly below 600W. Due to the small output energy, it is mainly used for punching and spot welding and sheet. Cutting. Its green laser beam can be applied in the case of pulse or continuous wave. It has short wavelength and good condensing properties. It is most effective for precision machining, especially for pulse processing under pulse. It can also be used for cutting, welding and lithography. . The wavelength of YAG solid-state laser cutting machine laser is not easy to be absorbed by non-metal, so it can not cut non-metallic materials, and YAG solid-state laser cutting machine needs to solve the problem of improving the stability and life of the power supply, that is, to develop a large-capacity, long-life optical pump. Excitation of the light source, such as the use of a semiconductor optical pump, can greatly increase energy efficiency.
Third, the comparison of CO2 laser cutting machine and fiber laser cutting machine
First of all, the traditional laser cutting and welding equipment as the mainstream uses CO2 lasers, which can stably cut carbon steel within 20mm, stainless steel within 10mm, and aluminum alloy below 8mm. Fiber lasers have obvious advantages when cutting thin plates within 4 mm. Due to the wavelength of solid lasers, they are of poor quality when cutting thick plates. The laser cutting machine is not omnipotent. The wavelength of the CO2 laser is 10.6um. The wavelength of the solid-state laser such as YAG or fiber laser is 1.06um. The former is easy to be absorbed by non-metals and can cut wood, acrylic, PP and plexiglass with high quality. Non-metallic materials, the latter is not easily absorbed by non-metals, so non-metallic materials can not be cut, but the two lasers are not good when they encounter high-reflection materials such as copper, silver, and pure aluminum.
Secondly, precisely because the wavelengths of CO2 and fiber laser are different by an order of magnitude, the former cannot be transmitted by optical fiber, and the latter can be transmitted by optical fiber, which greatly increases the degree of flexibility of processing. In the early days before the introduction of the fiber laser, in order to realize the three-dimensional processing, we used the optical joint technology to guide the CO2 laser to the surface of the three-dimensional curved surface through a highly sophisticated dynamic combined mirror system to realize the three-dimensional processing of the CO2 laser. The limitations of precision machining technology are mainly in the hands of a handful of developed countries in Europe and America. They are expensive and have high maintenance requirements. They have gradually lost their market while the market share of fiber lasers has gradually expanded. The fiber laser can be transmitted through the optical fiber, and the degree of flexibility is unprecedentedly improved. Especially for the automotive industry, since it is basically a thin plate surface processing of about 1 mm, the fiber laser is matched with the same flexible robot system, and the cost is low and the number of fault points is small. The maintenance is convenient, the speed is very fast, and the market is firmly occupied by the people.
Thirdly, the photoelectric conversion rate of fiber laser is as high as 25% or more, and the photoelectric conversion rate of CO2 laser is only about 10%. The advantages of fiber laser in terms of electricity consumption and supporting cooling system are quite obvious, if the manufacturer of fiber laser is more The price is a little more suitable and solves the thick plate cutting process. The threat of CO2 laser will be huge. However, fiber laser as an emerging laser technology is far less popular than CO2 laser. Its stability and reliability, and the convenience of after-sales service have yet to be observed in the market for a long time. More technical articles are available at the Metalworking Online Technology Center.
It is worth mentioning that, according to international safety standards, the laser hazard level is divided into 4 levels, CO2 laser is the lowest level of damage, and fiber laser due to short wavelength is harmful to the human body due to eye damage, which is the most harmful level. For safety reasons, fiber laser processing requires a fully enclosed environment.
In addition, the flexible processing system of fiber lasers with robots has a long history in the automotive industry and supporting industries. In the past, it was monopolized by foreign integrators. In recent years, due to the financial crisis and the continuous improvement of production technology in the automotive industry, especially domestic lasers. High-end technical manufacturers such as Huagong Laser Farley are working on technology under the support of national policies. In recent years, automotive white body welding, automotive instrument panel laser weakening, automotive airbag laser welding, automobile bumper, Flexible cutting of robots such as doors and center pillars, laser welding of automobile bumpers, on-line welding systems for automobile exhaust pipes, and laser automatic cutting devices for automobile shifting sets.
In summary, the direction of laser applications should be the application of high-power CO2 lasers on more stable, larger format, faster machines. For 3D surface machining up to 2mm, fiber laser is more advantageous.
Fourth, YAG laser and CO2 laser comparison
The YAG laser output has a wavelength of 1.06um, which is an order of magnitude smaller than the CO2 laser wavelength of 10.06μm. Therefore, it has high coupling efficiency with metal and good processing performance. YAG laser can be coupled with fiber, with time division and power division multiplexing system. It can conveniently transmit a laser beam to multiple stations or remote distance stations, which is convenient for laser processing. YAG laser can work in both pulse and continuous mode. The pulse output can be obtained by Q-switching and clamping mode. Short pulse and ultra-short pulse, so that its processing range is larger than CO2 laser; YAG laser has compact structure, light weight, simple and reliable use, low maintenance requirements and relatively low price, so its application prospect is promising.
The main disadvantages of YAG lasers are:
1. Its conversion efficiency is low, only 1-3%, which is about an order of magnitude lower than that of CO2 laser. 2. The internal temperature gradient of YAG laser rod during operation causes thermal stress and thermal lens effect. The average power and beam quality of the YAG laser are further limited; 3. The cost per watt of YAG laser is more expensive than the CO2 laser.
4. At present, the output power of the products is mostly below 600W. Due to the small output energy, it is mainly used for punching and spot welding and thin plate cutting.
V. Trend analysis of laser cutting equipment replacing traditional processing technology
Laser cutting is a technological revolution in sheet metal processing and a "machining center" in sheet metal processing. Laser cutting has a high degree of flexibility, high cutting speed, high production efficiency and short production cycle, which has won a wide market for customers. Laser cutting without cutting force, no distortion in processing; no tool wear, good material adaptability; whether simple or complex parts, laser can be used for precision and rapid prototyping; its slit is narrow, cutting quality is good, automation is high, operation Simple, low labor intensity, no pollution; can realize automatic cutting and nesting of cutting, improve material utilization rate, low production cost and good economic benefit. The technology has a long effective life. At present, most of the plates below 2 mm in foreign countries use laser cutting. Many foreign experts agree that the next 30-40 years is the golden age of laser processing technology development (the direction of sheet metal processing development). In recent years, China's sheet metal processing technology level and product quality have been rapidly developed, which is inseparable from the progressive use of laser cutting machines by processing companies.
In the sheet metal industry, laser cutting machines will replace CNC punching machines in a wide range. The advantages of laser cutting machines over CNC punching machines are as follows: 1. No need to open the mold, only the figure will be made on the computer, the product will be immediately Can come out, can quickly develop new products, but also save costs. 2. The laser cutting machine has an automatic tracking system, so it can complete the plane cutting, and can also complete all kinds of uneven surface cutting. 3, complex process requires CNC punching is difficult to complete, laser cutting can do. 4, can complete the processing of various complex structures, as long as you can draw any image on the computer, the machine can complete the processing. 5, the molded box (within 0.5 m thick) needs to increase the processing of the hole groove, the CNC punch can not be processed, the metal laser cutting machine can solve. 6, the surface is very smooth, the product grade is very high, CNC punch is difficult to do. More technical articles are available at the Metalworking Online Technology Center.
Due to the many advantages of laser cutting machines, with the development of the metal processing industry, the advantages of metal laser cutting machines are becoming more and more obvious, so the proportion of laser cutting machines is also growing.
Three-dimensional laser cutting has obvious advantages in improving product quality, production efficiency, shortening product development cycle, reducing labor intensity, and saving raw materials. Therefore, despite the high equipment cost and large one-time investment, many automobile and aircraft manufacturers in China have purchased 3D laser processing machines, and some universities have also purchased corresponding equipment for scientific research. Three-dimensional laser technology is bound to play in China's manufacturing industry. Growing bigger and bigger.
The most widely used field of laser cutting is the design and manufacture of automotive bodies. It is mainly used to develop new models, online cutting and deformation vehicles, such as cutting prototype parts, cutting and trimming of body panels, cutting steering wheel holes, body blocks. Wind panels, roof cover bracket holes, airbag components, hydroformed parts, etc. Companies such as BMW, Mercedes-Benz, Fiat, Volvo, Volkswagen, and Nissan all have five-axis laser processing machines for body machining. Three-dimensional laser cutting is also very useful in the processing of the body after assembly, such as opening the luggage rack with the same hole, the top cover rail hole, the antenna mounting hole, and modifying the shape of the wheel fender. In aerospace, this technology is used to punch, cut and trim aircraft parts of formed stainless steel, Inconel alloys, titanium and aluminum.
Laser three-dimensional cutting technology is also widely used in mold manufacturing, engraving, petroleum industry and other industries. In the printing industry, the laser engraving and cutting machine utilizes the high energy and high efficiency of the laser to ablate the rubber plate through program control, and the printed plate is not only low in cost, but also has fine engraving and high quality; The high-energy characteristics of the knife template are deeply ablated, and various high-precision die can be manufactured. In the field of mold manufacturing, it can be used to process molds, test molds, and manufacture molds. The combination of mold CAD and laser cutting enables the fabrication of complex structures inside the mold, such as deep holes, holes, hollow bodies, and complex cooling channels; the steel sheet is finely cut with a laser and then superimposed into a die or punch. In the petroleum industry, this technique is used to process slotted screens. More technical articles are available at the Metalworking Online Technology Center.
Many shipbuilders in the United States, Europe, and Japan have long used high-output CO2 laser cutting machine technology for shipbuilding and have achieved success.
These years of "precision shipbuilding" is familiar, to be true, to see the CNC cutting, the current domestic shipyard equipment is clearly not up to the technical requirements, people's attention is naturally directed to higher cutting accuracy Laser cutting, no doubt this will become the driving force behind the entry of CNC laser cutting machine into the Chinese shipbuilding industry. The rapid development of optoelectronic technology has greatly reduced the cost of laser cutting (yuan/kW), and the fierce market competition of various manufacturers for the first time will inevitably lead to lower prices of laser cutting machines, and ultimately make them The comprehensive economic benefits have formed a competition with CNC plasma cutting machines and have been gradually recognized and accepted by China's shipbuilding industry.
It can be said that laser cutting technology has penetrated into various fields of the national economy. It is foreseeable that in the next few years, laser cutting technology will be promoted and used in various manufacturing industries at a relatively high speed, which will make China's manufacturing industry develop in a highly sophisticated direction. Important contribution.
Sixth, China's small and medium power laser cutting equipment market scale analysis
According to "Industrial Laser Solutions" (ILS), in 2008, global laser processing equipment was about 6.36 billion US dollars; according to Handing Consulting, small and medium power laser cutting machines accounted for about 10% of the global market, and the market size is about 640 million US dollars. In 2009, affected by the global financial crisis, the growth of small and medium power laser cutting machine industry will be significantly slowed down. After 2010, growth will resume. By 2012, the global small and medium power laser cutting machine industry is expected to reach US$1.31 billion.
Chart 1 Global small and medium power laser cutting machine industry scale (unit: 100 million US dollars) Chart 1 In China, small and medium power laser processing equipment laser cutting machine and marking machine occupy 80% of the market share, is the most widely used in small and medium power laser processing Processing equipment. In 2008, the market size of China's small and medium power laser cutting equipment was 402 million yuan. In 2009, the growth rate of China's small and medium power laser cutting machines was slowed down by the global financial crisis. It is expected that the size of China's small and medium power laser cutting machines will reach 1.04 billion yuan in 2012 this year. Renminbi. Laser cutting machines as a new alternative to traditional tools face a broad market prospect.
Chart 2 2006-2012 China's sales of small and medium power laser cutting machine Unit: 100 million yuan Chart 2 VII, looking forward to the future China's laser companies have a cluster of clusters, mainly distributed in five industrial belts: Pearl River Delta, Yangtze River Delta, Central China, The Bohai Rim region, as well as the emerging Northeast Industrial Revitalization Zone. In addition, the western industrial belt will also take shape.
Laser processing is the largest project in foreign laser applications and an important means of transforming traditional industries. It is mainly kW- to 10-kW CO2 lasers, fiber lasers and watt-to-kilowatt YAG lasers for cutting various materials. Since the beginning of the 1970s, laser cutting technology has been developed and applied very fast, and the technology has become more and more perfect. According to estimates, in the next five years, the demand for laser products in China will exceed 60 billion yuan. At present, the industrial use of this technology is more extensive in industrialized countries. The main reason for the laser cutting technology to be used more is that laser cutting has small thermal deformation, high cutting precision, and easy to realize automatic cutting without one. By using an improved high-power laser cutting machine combined with an efficient and intelligent CNC system, the cutting speed is faster, the thickness is higher, and the quality of the cutting edge obtained is better, so that the laser processing technology, especially the high-power laser processing technology is obtained. A wide range of applications and developments. More technical articles are available at the Metalworking Online Technology Center.
China's main laser products are moving from single to multiple varieties. For example, 5KW and 10KW cross-flow CO2 lasers have been used in the industry. 3KW, 4KW, 6KW CO2 axial lasers have also been introduced, and semiconductor direct lasers have achieved 10KW power. In addition, the return of overseas students has quickly supplemented the vacant part of the laser industry in China, especially in the field of semiconductor lasers and fiber lasers.
The future development trend of lasers is concentrated in semiconductor lasers, fiber lasers, and disc lasers. China has been at the forefront of semiconductor lasers in the world, and IPG still maintains a leading position in fiber lasers. China should pay attention to the development of disc lasers. As the localization of lasers matures, the quality gradually increases, and the price of lasers gradually decreases. We have reason to believe that the era of universal application of laser cutting equipment is not far off.
Laser cutting is currently the most widely used laser processing technology in many countries. In many fields abroad, for example, the automotive industry and the machine tool manufacturing industry use laser cutting to process sheet metal parts. With the continuous improvement of the beam quality of high-power lasers, laser cutting has a wide range of processing objects, including almost all metal and non-metal materials. For example, lasers can be used to cut three-dimensional parts with high hardness, high brittleness, and high melting point in a complex shape, which is the advantage of laser cutting.
Taking metal cutting as an example, various processing methods present a situation of blooming, including laser, flame cutting, electric discharge machining, wire cutting, and water cutting. All kinds of cutting methods have their own advantages, and they all have certain limitations. From the various cutting technologies currently available to people, laser cutting technology is undoubtedly the best cutting method. In addition to the features described above, laser cutting has the advantages of low noise and low pollution. With the increasing awareness of environmental protection and the decline in the manufacturing cost of laser sources, the advantages of laser cutting technology are more prominent. The use of laser cutting technology to replace flame and plasma cutting will become the trend of cutting technology in the future. More technical articles are available at the Metalworking Online Technology Center.
Laser cutting uses a focusing mirror to focus the laser beam on the surface of the material to melt the material. At the same time, the molten material is blown away by a compressed gas coaxial with the laser beam, and the laser beam and the material are moved relative to each other along a certain trajectory. A certain shape of the slit. Laser cutting is the world's most advanced cutting process. Its biggest advantage is that because the laser spot is small and the energy is concentrated, the cutting slit is small, there is no dross, there is almost no thermal deformation, and the cutting surface is smooth. In general, the laser cutting process has the following characteristics compared with other cutting processes such as flame cutting, plasma cutting, high pressure water jet cutting, etc.
1. High precision: positioning accuracy 0.05mm, repeat positioning accuracy 0.02 mm2. Narrow slit: The laser beam is focused into a small spot of light, resulting in a high power density at the focus. The material is quickly heated to a degree of vaporization and evaporates to form a hole. As the beam moves relatively linearly with the material, the holes are continuously formed into slits of narrow width. The slit width is generally 0.10 to 0.20 mm.
3. The cutting surface is smooth: the cutting surface has no burrs, and the surface roughness of the cutting surface is generally controlled within Ra12.5.
4. Fast speed: cutting speed up to 10m/min, maximum positioning speed up to 70m/min, much faster than wire cutting.
5. The cutting quality is good: no contact cutting, the cutting edge is little affected by heat, and there is basically no thermal deformation of the workpiece, completely avoiding the collapse formed when the material is punched and sheared, and the slit generally does not require secondary processing.
6. Does not damage the workpiece: the laser cutting head does not come into contact with the surface of the material, ensuring that the workpiece is not scratched.
7. It is not affected by the hardness of the material to be cut: the laser can process steel plates, stainless steel, aluminum alloy plates, hard alloys, etc., regardless of the hardness, can be cut without deformation.
8. Not affected by the shape of the workpiece: laser processing is flexible, can process any graphics, can cut pipes and other profiles.
9. Non-metal cutting can be done: plastic, wood, PVC, leather, textiles, plexiglass, etc.
10. Saving mold investment: laser processing does not require molds, no mold consumption, no need to repair molds, saving mold replacement time, thereby saving processing costs and reducing production costs, especially for processing large products.
11. Material saving: computer programming can be used to cut the entire board material of different shapes to maximize the utilization of materials.
12. Improve the speed of new product development: After the product drawings are formed, laser processing can be performed immediately, and the new product can be obtained in the shortest time.
13. Safety and environmental protection: Laser processing has very little slag, minimal noise, clean, safe and pollution-free, which greatly improves the working environment.
The development of the cutting industry has always been inseparable from the development of metal manufacturing enterprises. Through close cooperation and technical exchange with these enterprises, the cutting industry has brought many different production concepts and challenging experiences and technologies. In order to optimize the structural performance of their products, modern metal manufacturing companies make products more economical, have shorter production cycles, and are more competitive in the international market. This requires new ideas and requirements for its original manufacturing technology and production process. Some of the ideas and requirements will be realized on the cutting equipment, which brings new topics and new design concepts to our cutting industry. More technical articles are available at the Metalworking Online Technology Center.
Compared with the international laser processing system, there is still a big gap in China's laser processing system. However, China's laser equipment manufacturers are steadily entering their reserves, and the domestic application market also has a lot of room for development. The laser industry will achieve unprecedented development in China. For the reasons, there are the following aspects:
1. The state attaches importance to the fact that government departments at all levels are actively paying attention to, planning and projecting projects, and various funds are being injected. In particular, the state emphasizes that the main body of the project is transferred from colleges and universities, scientific research departments to enterprises, which promotes independent innovation and technological upgrading of enterprise products.
2. All kinds of domestic manufacturing industries have accepted laser processing technology, which can increase the technical content of their products, speed up product upgrading, and adopt it to achieve the level of “agile manufacturing†and meet the market requirements for “personalized†products.
3. Domestically, the laser component supporting enterprises of the industrial group have gradually formed, and various laser processing system manufacturers with characteristics have been established. Domestically, four industrial zones for laser processing equipment manufacturing have been formed, which are mainly distributed in Central China. The Pearl River Delta; the Yangtze River Delta and the economically developed areas of the Beijing-Tianjin-Bohai Rim.
4. Some well-known laser processing manufacturers in the world invest and build factories in China; some are joint ventures in China, and the general trend is to enter and form international competition.
5. Domestically, it has gradually passed through the main laser and entered the market. Such as high-power axial-flow CO2 lasers, medium- and small-power metal cavity RF CO2 lasers, semiconductor-pumped all-solid-state lasers, fiber lasers, and multiplier DPLs, high-power diode modules, etc., are gaining momentum, entering the early stage of productization and entering the market. . Create conditions for the new application of domestic laser processing appreciation. More technical articles are available at the Metalworking Online Technology Center.
Laser processing technology has always been a high-tech of the country's key support and application, especially the government's emphasis on revitalizing the manufacturing industry, which brings development opportunities for laser processing technology applications. When the country formulates the medium and long-term development plan, it also lists laser processing as a key supporting technology because it involves national security, national defense construction, high-tech industrialization and the development of science and technology frontiers, which raises laser processing to a high level. The degree of attention will also bring great business opportunities to the manufacture and upgrade of laser processing machines. Due to the various propaganda, display, popularization and user training for the domestic market, the market for laser processing has been greatly expanded, giving domestic users the confidence and determination to adopt this advanced manufacturing technology, and the more laser processing is achieved. The more widely used external environment, this is what we often say about the market. The market is driving the hot sales of laser processing machinery and forming a chain reaction. As a result of this promotion, more than 200 laser processing machine manufacturers have been formed, employing nearly 20,000 people, of which about 50% of the scientific and technical personnel, about 30% of employees with intermediate and senior titles, has formed a considerable strength. Industrial team. At the same time, it has attracted the attention and follow-up of many laser processing equipment manufacturers around the world, and the domestic market has been internationalized.
