These projects have invested a total of 542 million yuan in research and development, and China has allocated funds of 124 million yuan. It has arranged 20 kinds of high-precision large-scale numerical control equipments with high technical difficulty, high import prices or foreign imports to China; Research on the industrial support technology of the batch mid-range CNC machine tools and CNC system production base; research on a number of basic common technologies such as numerical control system, servo drive technology, and high-speed spindle and other key functional components.
At present, these batches of scientific and technological projects have achieved initial results, and some key technologies have made breakthroughs in research and development, and a number of high-precision large-scale numerical control equipments have been developed. The research and application of basic common technologies have also achieved results.
Most of the 20 high-precision large-scale CNC equipment have been delivered
The scientific and technological research of 20 kinds of high-precision large-scale numerical control equipments arranged by the state has been completed, and most of them have been delivered yet.
For example, the gantry-type five-axis linkage hybrid machine tool jointly developed by Qiqihar No. 2 Machine Tool Plant, Tsinghua University and Harbin Electric Machinery Factory is mainly used for processing curved parts such as large turbine blades; research and production by Jinan No. 2 Machine Tool Plant and Beijing University of Aeronautics and Astronautics High-speed five-axis gantry machine tool, mainly used for processing large water pump blades of “South-to-North Water Transfer Projectâ€; the five-axis linkage blade machining center developed by Beijing Electromechanical Institute High-tech Co., Ltd. for Dongfang Steam Turbine Works can meet the processing quality and processing of large blades of 600MW steam turbines. Efficiency requirements, the price is only one-third of the imported similar machine tools.
The multi-axis turning and milling composite machining center developed by Shenyang Machine Tool is mainly used for the processing of complex shape parts such as pump body, precision connector, plug-in commutator and spiral blade assembly, diamond tooth gear drill bit, especially suitable for the new defense industry. The development of technical products. The large-scale CNC turning machining unit independently developed by Nanjing CNC Machine Tool Co., Ltd. has the characteristics of large torque, good rigidity, high precision and good dynamic characteristics of the whole machine. It is an urgently needed equipment for processing large pump parts.
The five-axis floor-type CNC milling and boring machine developed by Jiangsu Duoling CNC Machine Tool Co., Ltd. is mainly used for processing large and medium-sized diesel engines and large and medium-sized complex structural parts. It is especially suitable for high-speed and high-efficiency machining of complex parts with space curved surfaces.
