Equipment manufacturing industry is a kind of fundamental and strategic industry, providing technical equipments to national economic development and defence construction. As well, it is also the heart of industry and the lifeblood of national economy, providing machine tools to different departments of national economy and bearing the responsibility to promote the development of related industries. Last but not least, it is also an important back-up of building an innovation-oriented country. It is of great importance to improve the capability of independent innovation of laser machining equipments as well as to build an innovation-oriented country. Actually, laser beams have a dozen advantages, such as excellent monochromaticity, high energy-density and good space and time control and so on and so forth. At present, laser beams have been widely used in the field of material processing. For conventional usage, laser machining technology has been always used for metallic material’s laser welding, laser cutting, laser drilling, laser marking, laser surface heat treatment, laser rapid prototyping and laser carving and so on. With the birth of the latest components, the constant progress of laser technology and the appearance of new materials and workmanship, laser machining technology has received frequent usage in different industries. Laser machining has many applications, including manufacturing of automobiles, aviation and aerospace, electricity, chemistry, and medical appliance and so on. Compared with the cnc (computer numerical control) technology, laser machining technology has become the core technology of automation of industrial production, and owns the incomparable advantages over the ordinary processing technology.

China’s high power laser processing industry is at the beginning and developing stage; when compared with the developed countries with advanced technology such as America, Japan and Germany, China still lags behind. In the field of laser processing application, CO2 laser is wildly used in the form of cutting and welding with respective percentage of 70% and 20%. Laser is the heart and engine of laser machining equipments. The development of China’s high power laser is just at its early stage; therefore, there is a long way to go and a lot to improve. China has spent a large sum of money on developing various laser equipments in Huazhong University of Science and Technology. Great achievements have been made, but for its kilo-wattage lasers there is not sufficient preponderance over the products of DINGHONG, and furthermore, its industrialization is relatively backward. Accordingly, that’s why private capital goes into laser, a kind of high technology. It has always been a dream for China to produce and develop high power laser, because it is of urgent and practical importance to develop CO2 axial-flow high laser either for the purpose of rapid developing laser machining industry or breaking the situation of backward high power laser machining technology. At present, China’s laser has realized industrialization and most of them are hundred-watt lasers. In this field, there is still a gap between China and foreign countries, because of its low technical merit and less independent intellectual property. Most laser equipment manufacturers in China prefer to provide low-end equipments；therefore，many key components of laser machining equipments need to be imported from abroad. Although China’s laser technology stands in the front ranks of the world, the development of laser industrialization still lags behind the international advanced standard. High power axial-flow CO2 laser with independent intellectual property which is produced and developed by DINGHONG, really shortens the distance with the most advanced laser equipment technology in the world. Laser machining is the biggest project in the foreign laser technology application and the major technology in use should be thousand-watt high power CO2 laser and hundred-watt-thousand-watt YAG laser. They are used in the cutting, welding, drilling, carving and heat treatment of various materials. Some European countries have well developed laser industry and their high power laser technology has become mature. They combine the laser with cnc(computer numerical control) technology, advanced optical system and high-precision and automatic workpiece localization to develop and produce processing equipments. This kind of combination has become a developmental tendency of international laser machining industry. At the same time, some foreign countries have combine laser cutting and mould stamping into one machine tool, so as to produce laser punching machines with the multi function of laser cutting and high speed and efficiency of punching process. This kind of laser punching machine can carry out the processing of complicated cutting, drilling, marking and carving and so on. Besides, laser rapid prototyping technology is able to make moulds quickly and also can make metal mould by melting metal powder.

All governments have given full support to the development of laser industry, such as America’s “Laser Fusion Plan”, Germany’s “2001 Action Plan”, England’s “Arviel Plan” and Japan’s “Laser Research Five-year Plan”. At the same time, China also supports the development of laser industry by “Torch Plan” and “863 Plan”. In the processing industry, many developed countries have stepped into the laser processing time. The laser processing of Japan has taken up more than 10% of the whole world. In the area of laser medical treatment and laser inspecting technology, America secures a leading position and has become the first country to introduce high power laser to automobile industry. And in the respect of laser materials machining equipments, Germany prevails ahead. Trumpf whose output of laser machining equipments has ranked the first throughout the world is a Germany enterprise. According to the statistics, there are more than 5000 laser job shops around the world, mainly distributed in America, Japan and Europe.

With high performance-price ratio of its products, DINGHONG has become the leading enterprise in the manufacturing of high laser machining equipments at home. Furthermore, DINGHONG also provides machine tools for the manufacturing of inner and outer package, electricity, machinery, automobiles, aviation and navigation, and aircraft carriers and so on. The high power axial-flow CO2 laser produced and developed by DINGHONG has not only the independent intellectual property but also the following functions:

① The vacuum seal of working gas’s axial-flow system and laser cavity; the rapid speed, stability and reliability of the flowing gas.

② The improvement of the power capacity of direct-current exciter switches with a working voltage of 10-20kw and a maximum working current of at least 1.2A.

③ High stability of the machinery and optics of laser cavity; requirement of rational structure, vacuum seal, easy adjustment and locking function in order to ensure the stability of laser output.

④  The mechanical design of the whole machine requiring rational structure, convenient repair and the function of shockproof and dustproof.

⑤  PLC programmable controller and operation interface of man-machine interaction.

⑥  Water cooling system being one of  the key equipments to ensure the stability of high power laser and the proper operation with the function of ultra cleanness and constant temperature as well as automatic alarm and lock when lack of water or over temperature.

We are so glad to see that DINGHONG, as a private-owned enterprise, has made a major breakthrough in the laser processing industry especially in the key technology of high power laser. DINGHONG has managed to make its products number one in the home market and reaching the international standard. As a private-owned enterprise, DINGHONG has been always insisting on independent innovation and does make great achievements. What’s more, DINGHONG has made great contribution in improving the self-reliance equipment technology for China. Here we sincerely hope that DINGHONG will be able to apply its laser processing technology to important areas and projects of key technical equipments and further to give full play to its high-level and high-efficiency technology to the key technical equipments!
