First, the industry is picking up, the demand structure is upgrading, and the differentiation of business operations is intensifying. 
In 2017, China's machine tool industry continued its warming trend at the end of 2016. Machine tool imports increased by double-digit year-on-year, and some industries and enterprises achieved recovery growth. Taking tools as an example, according to the statistics of the key enterprises of China Machine Tool Industry Association, the sales revenue of the tool industry in the first three quarters increased by more than 20% year-on-year. The division of industry enterprises has intensified, and some enterprises have obvious effects in transformation and upgrading. They have outstanding performance in some key market segments. Some enterprises have difficulties in operation, high debt, sustained losses, and even unsustainable. For example, enterprises such as Dalian Machine Tool have entered bankruptcy and reorganization. program. Second, Premier Li Keqiang cares about the development of machine tool industry. On July 10, 2017, Premier Li Keqiang visited Qinchuan Machine Tool Group Co., Ltd., focusing on the precision grinding machine constant temperature assembly workshop and robotic reducer digital workshop, China Machine Tool Industry The chairman of the association, Long Xingyuan, chairman of Qinchuan Machine Tool, accompanied the Prime Minister. The Prime Minister is very concerned about the equipment manufacturing industry and puts forward the hope that China's manufacturing industry, especially the basic equipment manufacturing industry, should be well done, and encourage the whole industry. We must take "Made in China 2025" as an opportunity to strive for innovation and revitalize China's manufacturing industry. Contribute. In August 2017, Zhang Zhigang, the chairman of Jinan Second Machine Tool Group Co., Ltd., was invited to participate in the premier forum to discuss “promoting the construction of a strong country and continuing to promote economic restructuring and upgradingâ€. 
3. Miao Wei attended the on-site meeting of key application areas of domestic CNC system. “Domestic CNC system application demonstration project†was launched. 
On March 28th, 2017, the on-site meeting of the key application areas of domestic CNC system was held in Beijing, and the high-end CNC machine tools and basic manufacturing equipment technology special project (04 special project) results application and promotion on-site meeting, the party secretary of the Ministry of Industry and Information Technology, minister Miao圩 attended the meeting and gave a speech. After more than eight years of special implementation, a number of gratifying results have been achieved. First, to enhance the ability to innovate, the common technology research and innovation platform construction is steadily advanced. The performance of heavy forging equipment and some machine tools has reached or is close to the international advanced level. Second, significant breakthroughs were made in core components such as CNC systems. The gap between the function and performance of the domestic CNC system and the international advanced level has been greatly reduced. The key functional components such as ball screw, guide rail and power tool holder are close to the international advanced level in key indicators such as accuracy and reliability. The third is to adhere to the demand orientation and continuously improve the equipment support capability in key areas. For example, the “no problem†of key manufacturing equipment required for typical products in the aerospace industry is gradually being solved. At the same time, the “Domestic CNC System Application Demonstration Project†has been fully launched in 2017, and the CNC equipment for the 11th Military Enterprise Group will gradually use the “Chinese Brainâ€. The domestic CNC system application demonstration project is a major special project of the domestic CNC system led by the Ministry of Industry and Information Technology. It mainly supports Huazhong CNC, Guangzhou NC, Dalian Guangyang, Shenyang Gaojing and Aerospace CNC. The key technologies of the high-end CNC system are independently developed in the military. Application in the field to achieve localization of high-end equipment. Fourth, the Ministry of Industry and Information Technology's first batch of intelligent manufacturing solutions supplier catalogue 
The Equipment Industry Division of the Ministry of Industry and Information Technology organized the first recommendation of the first intelligent manufacturing system solution providers in 2017. On November 13, the Ministry of Industry and Information Technology publicized the first batch of recommended catalogues, and related industries such as Huazhong CNC and Chongqing Huasuo Robot were selected. In 2017, intelligent manufacturing is continuously deepening at the policy level and at the market level. The intelligent manufacturing standardization construction is also steadily advancing. The Sino-German Intelligent Manufacturing/Industry 4.0 Standardization Conference, the National Intelligent Manufacturing Standard System Construction Guide Revision Work Startup Meeting, etc. Both indicate that smart manufacturing is moving deeper. V. The formulation of the “Group Standards for Machine Tool Associations†officially launched the in-depth development of industry standards 
In October 2017, the “ISO/TC 39/SC 2 81st Meeting†hosted by the National Standards Committee and hosted by Beijing Machine Tool Research Institute and Qinchuan Group was held in Xi'an. The meeting discussed 11 standards including the “International Standard for High-end CNC Machine Tool S Test Pieces†and ISO 13041-2 “Test Conditions for CNC Lathes and Machining Centers—Part 2: Geometric Accuracy Inspection of Vertical Workpiece Axis Machinesâ€. proposal. The ISO international standard setting procedure consists of five phases: NP (Work Project Proposal), WD (Working Group Draft), CD (Committee Draft), DIS (International Standard Draft), and FDIS (International Standard Final Draft). Since the introduction of the "S test piece", after four years of hard work in six international conferences, a CD (committee draft) has been formed. After the discussion, revision and improvement of the S test piece standard CD (the committee draft), the final The draft standard enters the DIS phase from the CD phase. In terms of industry group standard construction, China Machine Tool Industry Association officially launched the association's group standard project declaration in April 2017. At present, 11 standards have been identified for inclusion in the 2017 first group association standard-setting project. Sixth, the four projects of the machine tool industry won the first prize of the 2017 Machinery Industry Science and Technology Progress Award
