On June 26, the Ministry of Science and Technology, the Ministry of Industry and Information Technology organized the National Science and Technology Major Project ("CNC Machine Special Project") conference for the "High-end CNC Machine Tools and Basic Manufacturing Equipment." The conference was chaired by Jiemin, a major special office of the Ministry of Science and Technology. Luo Junjie, deputy director of the Department of Equipment Industry of the Ministry of Industry and Information Technology, and Lu Bingheng, the chief technical officer of the Ministry of Industry and Information Technology, introduced the achievements and applications of the implementation of CNC machine tools. The reporter learned that CNC machine tools are the “working machine†of the industry, and the development of high-end CNC machine tools is not only the objective of supply-side structural reforms in the industrial and informatization fields, but also the objective need to accelerate the building of manufacturing powers, and it is also a strategy for deepening military-military integration and ensuring national security. Urgent requirements. From the earliest implementation stage in 2009, CNC machine tools focused on the development of machining centers and CNC lathes with a wide range of market demands. At the end of the “Twelfth Five-Year Plan†period, the product design and manufacturing capabilities of China's machine tool companies have been significantly improved, and the international competitiveness of high-end CNC machine tools and equipment has continued to increase. Machine tool companies have developed a large number of new products that meet market demands. Manufacturing technologies such as gantry machining centers and 5-axis machining centers have matured. The performance of heavy-duty forging equipment is close to the international advanced level. The precision horizontal machining centers have independent intellectual property rights. The core technology of flexible manufacturing systems. CNC machine tool special deployment implements the entire industrial chain layout, domestic CNC system realizes the original surpass of some technologies (such as embedded integrated numerical control device hardware platform, etc.). The company has mastered the hardware and software platform design and mass production technology of the CNC system, and has reached the international mainstream product technology level in key technical indicators such as multi-channel, multi-axis linkage and high-speed interpolation. In 2016, the high-end numerical control system specially supported by CNC machine tools has accumulated more than 1,000 sets, and the domestic market share has increased from less than 1% before the special launch to about 5%. The mid-range CNC system has achieved mass production. The domestic market share has increased from 10% to 25%, and three industrialized production bases have been formed. The total number of CNC systems specifically supported has achieved sales of nearly 4 billion yuan. The key functional components such as ball screws, guide rails and power tool holders are close to the international advanced level in terms of accuracy, reliability and other key indicators. The high-end numerical control machine tools represented by five-axis machining centers are used for batch demonstration applications in areas such as aircraft typical structural parts, space complex and precision structural parts, and components of flying missile engines, and are used in large aircrafts, new-type fighter aircrafts, lunar exploration projects and other countries. Major special projects and key projects provide key manufacturing equipment. For example, the successful development of the "Great Power" such as the large-size die forging press of 80,000 tons and the tension-stretching machine of the 10,000-ton aluminum sheet marked that China's aviation profile manufacturing has entered the world's advanced ranks. Large space tank sets of welding equipment, large-scale strong spinning equipment, automatic drilling and riveting equipment and other aerospace special manufacturing equipment have provided strong support for the successful completion of launch missions such as the Long March 5 and Tian Zhou No. 1. In the field of automobile manufacturing, the large-scale rapid and flexible automatic stamping production line developed by Jiji has successfully exported nine production lines over the past five years, with a domestic market share of more than 70% and a global market share of more than 30%. According to Lu Bingheng's introduction, at the end of 2016, the standard of S-shaped test pieces for testing the accuracy of 5-axis linkage machine tools independently proposed by China has passed the examination and approval by the International Standards Committee, and has achieved a breakthrough of the standard “zero†in the field of high-end CNC machine tool testing. Regarding future development, Luo Junjie stated that CNC machine tools will focus on the deployment of an innovation chain around the industrial chain, improve the capital chain around the innovation chain, and comprehensively upgrade the level of R&D, manufacturing and industrialization of key components represented by numerical control systems, and strive to overcome the Reliability and Accuracy Retentive Technology; Increased application verification and demonstration to meet new national strategic needs and provide support for the full implementation of “Made in China 2025â€. At the same time, it will continue to explore long-term mechanisms for industrial common technology research, further consolidate technical research and high-end talent bases, and continue to increase the implementation of process verification and user-oriented demonstration applications in the development of specialized equipment to optimize product performance, enhance reliability, and complete Group process and intelligence level. Actively build a production-demand docking platform for the machine tool industry and aerospace, automotive and other key areas. The machine tool companies and users jointly carry out pre-research to provide users with complete solutions including equipment and typical process solutions. The USB 3.2 specification absorbed all prior 3.x specifications. USB 3.2 identifies three transfer rates – 20Gbps, 10Gbps, and 5Gbps.

Key characteristics of the USB 3.2 specification include:
Defines multi-lane operation for new USB 3.2 hosts and devices, allowing for up to two lanes of 10Gbps operation to realize a 20Gbps data transfer rate, without sacrificing cable length
Delivers compelling performance boosts to meet requirements for demanding USB storage, display, and docking applications
Continued use of existing USB physical layer data rates and encoding techniques
Minor update to hub specification to address increased performance and assure seamless transitions between single and two-lane operation
Improved data encoding for more efficient data transfer leading to higher through-put and improved I/O power efficiency
Backwards compatible with all existing USB products; will operate at lowest common speed capability
