Great breakthroughs in high-end CNC machine tools and manufacturing equipment

In terms of numerical control systems, multi-axis multi-channel and bus-type high-end numerical control device prototypes have been developed, and independent intellectual property rights have been formed in multi-axis linkage interpolation algorithms and error compensation core technologies. At present, major technological breakthroughs have been made in the "high-end CNC machine tools and basic manufacturing equipment."

Through the implementation of the “Eleventh Five-Year Plan”, “High-end CNC Machine Tools and Basic Manufacturing Equipment” has broken through a number of key technologies such as high-speed, high-precision motion control and reliability design, and has completed the development of over a dozen of international advanced technologies. Heavy equipment played an active role in the response of the equipment manufacturing industry to the financial crisis. It can meet some of the needs of the aerospace and other four major fields and completed the special “Eleventh Five-Year Plan” research objectives.

The world's largest 36,000 tons ferrous metal vertical extrusion machine has been put into production a few days ago, solved a number of key technologies such as transmission and control operating system design and manufacturing, and achieved a major breakthrough in extrusion process technology.

The successful development of this equipment has enabled foreign companies to reduce the price of large-diameter, thick-walled steel pipes from 180,000 yuan/ton to more than 50,000 yuan/ton, and it is expected that the cost savings for related companies using these products will be more than 10 billion yuan per year.

The 10-meter numerically controlled bridge-type gantry turning and milling machine for processing large steam turbine casings and other key components of nuclear power units has mastered three key technologies such as beam assembly and processing technology, ensuring the machining accuracy of the machine tools. Two machine tools deliver the user. The super-heavy horizontal boring lathe with a rotating diameter of 5 meters and a load capacity of 500 tons breaks through core technologies such as super heavy-duty high-precision hydrostatic spindle technology. The main technical performance index of the machine tool has reached the international advanced level, has been delivered to the user, and completed a 110 megawatts supercritical nuclear power half speed rotor machining.

Large-scale CNC machine tools with large import volume and wide market demand have been deployed. Through the joint development of backbone enterprises, colleges and universities and users, key technologies such as structural optimization design and thermal compensation have been researched. Ningjiang Machine Tool, Beijing Institute of Precision Machinery and other units have completed the development of more than 30 models of precision, high-speed vertical and horizontal machining centers, CNC lathes, five-axis linkage machining centers and other new products, precision and speed can reach "11 V. At the end of the international advanced level, the MTBF of the host reached 900 hours. With the gradual introduction of the new batch of products into the market, it will effectively improve the technical level of domestic high-end CNC machine tools and promote the supporting verification of domestic high-end CNC systems and functional components.

In terms of numerical control systems, multi-axis multi-channel and bus-type high-end numerical control device prototypes have been developed, and independent intellectual property rights have been formed in multi-axis linkage interpolation algorithms and error compensation core technologies.

At present, Huazhong CNC, Guangzhou CNC and other units have completed the production of 50 sets of open all-digital high-end numerical control device prototypes, and relevant supporting verification work is in progress.

In the implementation process, the special project actively creates a research environment in which common technology and host and component support each other's cooperation. It requires universities and research institutes that share common technical issues to integrate superior resources and help enterprises solve practical problems in production and research and development. In terms of reliability technology research, Jilin University has developed a number of reliability specifications for CNC machine tools and developed a reliability test and test test bench, which provides reference for product reliability design and testing of key enterprises such as Shenyang Machine Tool and Dalian Machine Tool. .
