The research direction of laser cutting machine

With the development of laser industry, the use of laser cutting machine is more and more widely, but there are big gap with foreign technology, so the laser cutting machine how to development of our country to come out their own path, how to study is more suitable for the needs of the customers, what is the research direction of laser cutting machine? The following simple analysis:
(1) a new generation of industrial laser research, is currently in technical update period, its mark is the development and application of PuQuan diode pump solid state laser. Only to master the core technology, laser talent truly master the laser cutting machine, like the computer CPU.
(2) the application of laser micro processing research.
(3) and solid laser processing with high power CO2 laser and excimer laser machine research and development and research form a complete set of laser processing machine tools for special purpose, improve laser products on the production line and stable operation cycle.
(4) the intelligent machining system, system integration is not only the process itself, but with a real-time detection and feedback processing, with the establishment of the expert system, intelligent processing system has become the inevitable development trend.
(5) establish laser processing equipment parameter detection means, and methods.
(6) laser cutting technology research. The existing laser cutting system for secondary development and industrialization, provide performance is good, price cheap 2-3 axis CNC cutting machine, CO2 and carry out the corresponding research of cutting process, make the technology is widely used in material processing, automotive, aerospace and shipbuilding and other fields. Therefore should concentrate on laser peripheral device, such as system, process monitoring and control of light transmission, nozzle, floating device design and development as well as CAD/CAM, etc.
(7) laser welding technology research. To develop laser welding technology and materials, welding technology requirements for equipment and welding process parameter monitoring and control technology research, to grasp the ordinary steel, non-ferrous metals and special steel welding process.
(8) the laser surface treatment technology research. To carry out the CAD/CAM technology, laser surface treatment technology, material properties and laser surface treatment process parameters to monitor and control research, the laser surface treatment technology can be greatly used in production.
(9) laser beam quality and machining research peripheral devices. Study a variety of laser processing technology requirements about the quality of the laser beam, laser beam and processing quality monitoring technology, optical system and processing design and development. Only improve beam quality, can fundamentally improve the cutting quality of laser cutting machine.
Anyhow, laser cutting machine to study a long way to go, is the work of generations of people, whether common CO2 laser on the market, or advanced optical fiber laser, or more advanced lamp pumped lasers, all need through the practice step by step into practical.

Seven of the advantages of laser cutting machine

Can laser cutting machine as a means of emerging technology in recent years, the high energy density of laser beam to stay on the machining, the local heat to melt, and then using high-pressure gas blowing to slag forming and cutting seam.
Seven of the advantages of laser cutting machine:
1, narrow slot, high precision, good slotted roughness, after cutting without process after reprocessing.
2, laser high degree of automation, which can be totally enclosed processing, no pollution, low noise, greatly improved the working conditions of operators.
3, low processing cost. Equipment of one-time investment is more expensive, but a continuous, a large number of processing eventually make each parts processing cost is reduced.
4, laser for non-contact processing, inertia small, processing speed, cooperate with the numerical control system of CAD/CAM software programming, time saving, convenient and high overall efficiency.
5, laser of high energy density is enough to melt any metal, particularly suitable for processing some high hardness, high brittleness, high melting point of the other process methods are difficult to machining materials.
6, the energy density of the laser processing is very big, time is short, small heat affected zone, small thermal deformation, thermal stress is small, with a laser is a mechanical contact processing, no mechanical stress to artifacts, is suitable for precision machining.
7, laser processing system itself is a set of computer system, can the convenient arrangement, modifying, suitable for processing, especially for some contour shape complex sheet metal pieces, not more batch quantities, short product life cycle, from technology, economic cost and time perspective, uneconomic of mold manufacturing, laser cutting is particularly advantageous.

Laser cutting machine domestic enterprises transformation analysis

Transformation, which has been used bad words, in the present moment has been as much shouted "Wolf coming", for many people and businesses lose vigilance and fresh, but the two words are related enterprise survival. Especially in large and medium-sized manufacturing enterprises, is the traditional channel and the team, talk easy transition. Nokia's corporate culture, management norms, is the world's top patent innovation, but why a takeover by Microsoft? The answer is simple, nokia and achievements of his time with "by" disappear, because no timely and successful transition.
For the enterprise, there are two kinds of transformation. The first kind, forced to transition. While concentrating on problem cannot solve, reversed transmission enterprise transformation, the transformation cost is very big, is also very painful, but not transformation will be boiled frog, slowly dies. The second transition, is foreseen type transformation. Like that year sell PC business to lenovo, IBM is near the cheap PCS sold a high price in advance, IBM finish the transition ahead of time. Laser cutting machine industry development up to now, has also go to the edge of the transition must, as to why the transformation, the above two factors or both.
Ten years of China's accession to wto, China's rapid economic expansion, economy heading for the world ten years, and laser cutting machine market and technology rapid development of ten years. In these ten years, through the introduction and imitation, laser cutting machine in threshold quickly reduce, localization of progress is accelerated, the private enterprise embolden laser cutting machine, and international brand takes root, more ground, more local and China. However, laser cutting machine, as a kind of general machinery industry development up to now, around the world have been gradually mature, but for China, in brief is still too early to mature. Thering is no lack of in the industry believe that laser cutting machine industry has a person, is a sunset industry by reason of the technical research and development, potential growth space, as well as competition and profits. Can't see the cornucopia really can let a person produce a feeling of desperation, but laser cutting machine industry is really at the end of their tether? Not necessarily.With the echo of a pulse of laser cutting machine industry is China's economy, because after exploding market development on track, covered in the past rapid development when contradictions highlight out at this time. Conflict for a while, the interests of all parties, all kinds of different thoughts and voices coexist in the world, everywhere is full of fickleness and anxiety, but instead of the international capital market in China is more and more attention.
At present, the historical and realistic problem in front of the laser cutting machine industry is: as a result of the research and development of production technology backwardness and blank market hot streak of overlay, form a laser cutting machine profiteering era. Has attracted many international Grosvenor LTD handsome, this has happened many local tyrants domestic industry, have also brought a lot of lines, supply caused a slowdown in China, the situation of excessive competition.
Laser cutting machine industry has some characteristics of need to transition to cause our attention, otherwise don't transformation is to die, the transformation is dead.
1, after several rounds of price wars and many large-scale price reduction tide, conventional machine machine sales price plummeted, from profitable until thin. Price competition in the industry to become a "tactic" is often used, formed the price inertia - sales price = = total profits. Market problems, all to depreciate against, so do not hesitate to drop mass reduction and damage the interests of the brand image, customer and their own stand-alone profit. Is likely to be encountered during the transitional period of competitors and peer price tactics, boil but will probably get transformation.
2, the domestic enterprise of conventional metal laser cutting machine laser cutting machine to sell cabbage price by weight, but its core technology has been to imitate, have never seen beyond. Of the conventional machine, including host, are seen a lot of laser cutting machine several pioneers pull up a vote of the people dare to start production. For the production technology, most companies said no pressure, produced by laser cutting machine can run, the price is not expensive. But to say lines leading improvement, energy efficiency, this on domestic brands are relatively rare. Most real leading technology from one of the few international laser cutting machine, dare and competing against one of domestic enterprises, are few. Formation of the situation is, on the basis of can barely products, for innovative research and development, think with their existing technology enough, there is no need to spend effort and money to improve and innovation. The equipment from the technical level and the formation of the concept in the last few years is really practical, but after the market environment changes, to maintain food would be difficult. Turn at all is a problem, not a moment to see could not be living, but transformation, spend money can research the results? Research out of the market can be approved? Be industry leader runs, was "to" imitate, earnest research really is a way out?
3, laser cutting machine in China market, due to product quality and price positioning in the eyes of practitioners of enterprises including the objective existence, and in turn affect product pricing and customer purchasing. Inline took a half high-end products into two categories: one kind is imported laser cutting machine, another kind is large domestic laser cutting machine, half the class is the product with high price (although has relationship with the quality, but more due to pricing, ignoring the low-end demand). A half high-end market is divided into two categories: one kind is large state-owned enterprises and foreign investment projects, another kind is design institute to participate in the project market, half the class is a big customer market - large purchase quantity. Such classification habit has deeply rooted in the consciousness of some practitioners, although age and great changes have taken place in the market. Brand is established, the market for their established brand awareness can be changed? How to go to new price positioning and product positioning?
4, most of domestic laser cutting machine industry brand features: poor market or enterprise development is blocked, would rather be fought relegation than when the first person to eat crab, but if you glimpsed a business profitable, herd, regardless of tuck in. As a result, not transformation, product, service, serious homogeneity, only shopping prices; Once saw another enterprise in other field trips to new way, profitable, a clap his head in the direction of the transformation, also listed machines to produce the discovered areas have emerged after the transformation of homogeneity, have to continue to the next cycle.
For small businesses, small brands, in the case of output and small size, the quantity of a month YiErShiTai can maintain enterprise operation, although do not. But not the transformation and upgrading, most large and medium-sized enterprises laser cutting machine will surely downgrade in the next 3 to 5 years, die and is unlikely to fall into the second - and third-tier brand or very likely.
For some foreign brands and parts of domestic laser cutting machine of state-owned enterprises in deep system, not contact with broader civilian markets, inevitably lead to highbrow, under the extrusion of domestic brands and international strong corporation, will be unsustainable. So laser cutting machine industry, the transformation of medium enterprises is imperative.
