1. An important foundation for CNC technology manufacturing
The technical level and modernization level of the equipment industry determine the economic level and modernization level of the entire national reel slitter. CNC technology and equipment development enable emerging high-tech industries and cutting-edge industry enabling technology and the most basic equipment. Ma Ping Zhang slitter Kesi once said, "The difference between various economic eras is not in what is produced, but in how to produce, and what labor materials are used to produce the rewinding slitter. Manufacturing technology and equipment are based on human production activities. The most basic production materials, and the CNC technology is based on today's advanced manufacturing technology and the core technology of the corrugated paper cutting machine. Therefore, experts predict that the competition in machinery manufacturing will be the competition of the actual CNC technology.
Numerical control technology is a technology that uses digital information to control mechanical motion and work processes; the basics of rewinding and slitting machines for automated, flexible, and integrated production in the manufacturing industry; materials that are essential for improving product quality and labor productivity Means; an important strategic material for the modernization of the national defense; prime factors are related to the strategic position of the national war slitter and an important basic industry that reflects the country's overall national strength. Nowadays, the manufacturing industries of various countries in the world widely use numerical control technology to improve the manufacturing capacity and the level of spicy slitting machine, and improve the adaptability and competitiveness of the dynamic and changeable market. Vigorously developing advanced manufacturing technology with CNC technology as the core has become an important way for all countries in the world to speed up economic development, improve comprehensive national strength and national status. In addition, various industrial developed countries in the world have listed CNC technology and CNC tape slitting machines as national strategic materials. Not only have they taken major measures to develop their own CNC technology and their industries, but also on the "high precision" slitting machine Tool holder; the key technology and equipment of numerical control implement the policy of blockade and restriction on the even country.
According to the specific needs of the national economic development and the key construction projects of national business card slitting machines, design and manufacture "high, precise, sharp" major CNC equipment, break the foreign blockade of double-sided adhesive slitting machines, master the key technology of CNC equipment, and create China CNC machine tool brand, increase market share, and the key to comprehensively improve the core competitiveness of the base manufacturing equipment of Ou's basic manufacturing equipment.
Second, the development trend of CNC technology
The early CNC system of satin cloth slitting machine used perforated paper tape to transfer the processing program. The special CNC device reads the processing code, performs identification, storage and calculation, and outputs the command pulse of the corresponding fax paper slitting machine to drive the servo system. Small computers appeared in the mid-1970s. Because of its low price, superb data processing and input and output power small rewinding and slitting function, it is quickly applied to the control system of CNC machine tools, so-called computer numerical control (CNC) and direct numerical control (DNC) systems appear. Since the age of the ninety aluminum ribbon slitting machine, the development of computer technology has changed rapidly. The general-purpose computer has developed from an 8-bit machine to the Pentium era. Its speed and function have been hundreds of times faster than that of the 8 Shenzhen slitter machine. So that various numerical control functions can be realized by software on the general microcomputer, and the numerical control technology has undergone profound changes. The self-adhesive slitting machine on the PC is rich in software resources and friendly man-machine interface, which is unmatched by other CNC systems. The open computer-based CNC system has become the development trend of the world's CNC technology export slitting machine technology, and the application scope of the CNC technology based on the PC is rapidly expanding.
With the continuous development of science and technology in the winding film slitting machine exhibition, the development of CNC technology is getting faster and faster, and CNC machine tools are developing toward high performance, high precision, high speed, high flexibility and modularization. However, the development trend of the main web slitter is based on the "PC + motion controller" open CNC system, which not only has the strong ability of information processing web slitter, high degree of openness, precise motion trajectory control, and universal Features such as good performance, but also greatly improved the accuracy of the existing processing and manufacturing, the flexibility of the river cutting machine and the ability to meet market demand. The United States calls it a new generation of industrial controllers, and Japan says it will bring the third industrial revolution.
3. The way out of CNC in China
Looking at the current NC market in Ou, the multi-knife cutting machine in China has a certain gap in performance, appearance, and reliability from foreign products. Especially foreign units have strong funds, and foreign units are slitting machines. Customs seizes the Chinese market, and the CNC systems that can be produced in the dual country are sold at a reduced price, while the CNC systems that the dual country cannot produce are not only expensive but also have many cutting mechanisms for burning paper in Shandong.
Under the dual strategy of technology blockade and low price dumping by foreign CNC units, China's CNC industry has experienced ups and downs. Even the country has spent a lot of money to introduce the technology of supplying slitting machines into Siemens and FANUC, and hopes to absorb on this basis. Digest and develop Ou's own CNC technology. For example, Beijing Miyun introduced the CNC system of F supply slitting machine ANUC, which can be sold by FANUC to the couple. After the introduction of the dual country, FANUC announced that it would stop the production of the cutting machine and mass production, and the CNC system rewinding machine with better performance-price ratio, higher quality and smaller volume / The slitting machine is pushed to the Chinese market. This approach of following behind others is bound to be restricted by others and will always lag behind. What is the way out for CNC in China?
With the rapid development of computer technology, the inevitable trend of microcomputer-based open CNC technology development. In regard to the transmission of 1800 slitting machine CNC technology, even the country is in a relatively backward state. Open CNC provides a good opportunity for the development of the CNC industry in the even country. It strengthens and focuses on the research and support of the open CNC technology of Guangzhou slitting machine. Only in this way can the CNC industry in China even develop and grow, and it is possible to be an undefeated sealing tape slitter in the future market competition.
The School of Mechanical Engineering and Automation of Fuzhou University adheres to the purpose of accelerating industrialization with informatization, promoting the adjustment and optimization of aluminum foil cutting machines in manufacturing structure, and building high-level advanced equipment in Fujian. The development trend and demand of the customs modernization of intelligent control and equipment of the current cutting machine, vigorously strengthen the research and development of open CNC technology, and strive to provide the cutting machine Qingyuan for advanced manufacturing for the province to adapt to the challenges of economic globalization and informatization Technology and equipment.
