Precision Intelligent Inspection Precision component intelligent inspection is primarily geared toward industries such as aviation, aerospace, automotive, electronics, and shipbuilding. Leveraging the technological expertise of Nanjing University of Aeronautics and Astronautics, we have established an integrated “industry–academia–research–application” R&D system. Our mission is to conduct fundamental research, drive technological innovation, provide technical services, and facilitate the commercialization of results in the fields of online precision component inspection technologies and intelligent turnkey equipment, thereby delivering core technologies and equipment that support the flexibilization, automation, integration, and intelligence of production, manufacturing, and assembly processes. Centered on internationally advanced high-precision online measurement technology, we develop and manufacture automated online measurement systems for precision components, primarily for the real-time inspection of critical automotive engine parts such as cylinder blocks, cylinder heads, crankshafts, connecting rods, and camshafts. Supported by industrialization platforms including the Jiangsu Provincial Academy of Industrial Research’s Institute of Precision and Micro-Manufacturing Technology and the NUAA Pukou Advanced Manufacturing Technology Research Institute, our products meet the latest “intelligent manufacturing” requirements outlined in “Made in China 2025” from both precision and online perspectives, enabling full online inspection of automotive engine components. Guided by the vision of “Leading Precision Measurement, Creating Chinese Precision,” our business unit builds upon an entrepreneurial team and leverages the technological strengths of the Provincial Academy of Industrial Research and the NUAA Pukou Advanced Manufacturing Technology Research Institute to jointly achieve the industrial application of these technologies and maximize both their technical and societal value. Product Introduction: Online Measurement Technology and Turnkey Systems for Precision Part Machining As the aerospace and automotive manufacturing sectors continue to advance toward higher precision and greater intelligence, high-precision, intelligent online inspection technologies and equipment have become a critical bottleneck. Our product breaks through the following key technological barriers: (1) We have developed pressure-sensitive ultra-high-precision detection technology that overcomes the technical challenges of non-contact, high-precision measurement, achieving a measurement accuracy of 0.1 μm; (2) We have engineered multi-channel synchronous high-speed sampling technology with automatic compensation, addressing the issue of poor dynamic performance in multi-point data acquisition and attaining a measurement resolution of 0.05 μm; (3) We have solved the challenge of high-speed online inspection for complex, eccentric shaft-type components by developing high-precision, follow-up detection technology, reducing the maximum measurement time to less than 45 seconds and fully meeting the demands of online measurement; (4) We have created integrated detection technology for dimensional errors, geometric errors, and physical parameters, increasing inspection efficiency by more than 30%; (5) We have developed multi-parameter, high-precision, small-range, rapid, high-frequency detection combined with real-time fitting technology, enabling the simultaneous measurement of more than four parameters within a small range of 2 mm, with a sampling frequency exceeding 1,000 samples per second and a sampling accuracy of 0.2 μm. This product finds broad applications in the online measurement of core precision components throughout the machining processes in the automotive and aerospace industries.
