the inclusion of R & D projects in the 863 plan is advanced and strategic.
over the years, Wuzhong group has taken the task of revitalizing the equipment manufacturing industry of the Chinese nation, making the national mission the goal of enterprise technological innovation. This project is assigned by the Ministry of science and technology of the people's Republic of China and belongs to the National 863 plan. The development of its equipment is advanced and the technical level of tackling key problems in the industry. Its comprehensive strength marks the national level. The developed ckx5680 turning milling compound machining machine tool is characterized by its substitution for imports and breaking the blockade of Western technology. According to Jinmo, the project equipment is mainly used for the high-precision and efficient processing of key components of large high-end ship propeller, from customized laminated products to preformed composite inserts for hybrid forming process. The maximum machining diameter of the machine tool is 8.5 meters, the maximum load is 160 tons, and the positioning accuracy is 0.025 mm. These parameters are the same as or even exceed those of similar foreign equipment (at that time, only Coburg in Germany and Toshiba in Japan were able to produce such equipment). As a key component of large-scale high-end ship propeller, the manufacturing accuracy directly affects the stability, noise and other mechanical properties of the ship, and its processing requires high-end CNC machine tools. Previously, only Germany and Japan could manufacture the propeller and its price was expensive. The independent research and development of high-end CNC machine tools for propeller processing by Wuhan heavy industry group, which breaks the blockade and restrictions of foreign countries, is very important to improve China's ability to accelerate the implementation of China's high-end ship manufacturing industry in the marketIn 2002, under the organization and guidance of duanzhengcheng, academician of the Chinese Academy of engineering and professor of Huazhong University of science and technology, Wuzhong group, Huazhong University of science and technology and Zhenjiang Zhongchuan Wartsila propeller Co., Ltd. established a project team headed by the first expert of China's weaponry and the chief engineer of Wuzhong group, adopting the mode of production, learning, research and application, with the support of the National 863 plan, Independently researched and developed a CNC seven axis five linkage propeller processing heavy turning and milling compound machine tool with intellectual property rights. During the development of the project machine tool, the project team encountered various difficulties and overcame them one by one. Breaking through a series of key technologies and solving a series of key problems. Over the past 10 years, China's first large-scale high-performance CNC heavy-duty seven axis five Gang motor car milling compound machine tool for propeller processing has been developed from scratch, which has completed the whole process of propeller clamping at one time, and the efficiency has been increased by more than 3 times, fully meeting the design objectives of the project plan
the results of the project have achieved remarkable results in serving the social practice.
after the machine tool equipment was officially put into operation, various specifications of propeller products have been processed, and the processed propeller products can reach ultra-high (S-level) accuracy through user detection. Some propeller products have been exported for high-end luxury cruise ships in Italy and other countries. The innovative technologies and functional components of the R & D results of this project have been successfully applied to a number of other types of CNC heavy machine tools, and have made important contributions to improving the manufacturing capacity of China's high-end one computer output channel ships and power generation equipment, as well as national defense security. According to preliminary statistics, the new output value of this project has reached 681million. The project has been granted 1 invention patent, 4 utility model patents and 2 public invention patents; The R & D team published 15 papers. According to the appraisal organized by the Department of science and technology of Hubei Province, it has filled the domestic gap, has independent intellectual property rights, and its overall technology has reached the current international advanced level of similar machine tools. In 2011, this project won the first prize of China machinery industry science and technology award
the successful development and operation of the machine tool of this project has broken the technical blockade and restrictions of foreign countries, making China the third country that can manufacture such equipment, completing the qualitative leap from manual grinding to precision machine tool machining, greatly improving the product accuracy and production efficiency, marking that China can produce large marine silent propeller. At the same time, It will also realize the dream of several generations of Chinese shipmen to let the propeller work quietly and let the ship sail quietly
