With the rapid development of laser machining at home these years, laser machining technology stands out as a new force. DINGHONG Laser, in particular, has played an important role in the home market of laser machining equipments. The competition of quality, after-sales service and performance-price ratio of laser machining equipments has become increasingly fierce, however, it is DINGHONG Laser that remains NO.1 and surpasses the others.

After the procurement of the core technology of axial-flow high power CO2 laser and the purchase of the entire set of technology blueprints from Japan, DINGHONG DF high-precision and large-scale laser nc (numerical control) cutting machine finally came into being. With the continuous seeking of precision, trueness and practicality, it has become a classic product of DINGHONG. In the world today, high power nc laser cutting with high precision is unquestionably the most advanced laser machining equipment. DINGHONG has successfully made its fabrication techniques of laser machining equipments world class by making full use of the advanced technology from abroad. At the same time, DF high-precision laser cutting technology has also helped to fill a gap in home markets. To be more specific, nc laser cutting can be used in the following aspects:

· home textiles, fabric, drapery processing, diving suits, skiwear, garments, leather processing;

·the interior trimmings of automobiles and devices of aviation and navigation;

·variously contextures of massproduction in the form of coil;

·materials used for parachutes, pattern-painting tents, camouflage uniforms, antichemical products, rubber dinghy, and assault boats. (for both military and civil purpose)

The power of DINGHONG’s high power laser cutting machine should be between 1000W and 2000W and it is the customers’ choice to pick their laser freely. (150W is the highest power in our country while 1000W power has been the top all around the world.) The following aspects of innovation have embodied the high precision as referred above:

1 Theory Innovation

  DF high-precision laser cutting has adopted a more efficient method in the execution efficiency of interpolation algorithm and motion function, and another means called “ Image method for precision counting and arc growing method for minimum-span assurance” so as to improve its precision, speed and real time in interpolation.

2 Technology Innovation

(1)   Complementation of long-distance attenuation compensation and extreme-distance laser cutting;

(2)   Exploration of the software-control system with independent intellectual property.

3 Application Innovation

(1)   Adoption of superior-performance AC servo motor driving and sophisticated ball screw/directed structure of linear guide-way transmission;

(2)   Application of double-motor synchronous control technology.

In total, DINGHONG makes use of numerical control technology, optics and precision machinery to realize the innovation of integration technology as well as the nc laser cutting with high power, high precision and high efficiency. In China’s Giving Priority to Key Areas of High-tech Industrialization Manual, nc laser cutting with high power and high precision has clearly reflected that “laser machining technology and its entire set of equipment” is one of the key areas of high-tech industrialization which will be given priority to development. In this Manual, it has clearly stated that full play should be given to laser machining technology in the process of high-tech key area industrialization, the technology upgrade of pillar industries, and the transformation of traditional industries and crafting technology. In section 5 of Outline of China’s Medium- or long-Term Science and Technology Development Plan (from 2006 to 2020), eight items of key frontier technologies of our country have been listed in detail, with laser technology in the 7th position. The Outline points out that frontier technology is an important technology of great prospect and a significant foundation of high technology and the development of new industries. It is also the comprehensive embodiment of the innovation of national high technology. Last but not least, it is playing a leading role in the formation and development of China’s potential new industries. The products of DINGHONG help to improve the traditional processing methods since they can be widely applied and have prospect on the market. DF laser cutting of DINGHONG which has combined the Japanese technology and its own innovate technology, shows us the determination of DINGHONG staff to produce high-precision and high-efficiency products. It is the weapon of traditional processing methods to make achievements in processing industry, for instance, sewing manufacturing equipment. The successful production and development of DINGHONG DF laser cutting is of utmost significance because it will bring the industries of garment, leather manufacturing and national defence into a rapid development.
