Nanjing Gongyi High End Breakthroughs in Manufacturing

Nanjing Gongyi: Fortifying the Foundation of Manufacturing Power Through Cutting-Edge Technology

On December 29, the "Fortifying the Foundation for National Rejuvenation - China's Manufacturing Achievements Exhibition Under the 14th Five-Year Plan" kicked off at the National Museum of China. This exhibition systematically presents the development milestones of China's manufacturing industry since the initiation of the 14th Five-Year Plan. As a leading enterprise in China's rolling functional components sector, the company's exhibited high-end products fully demonstrate the independent innovation capabilities and supporting strength of China in high-precision core components.

01 High-End Breakthroughs: Realizing Localized Supporting in High-End Equipment Fields

The company showcased two flagship products: "Forced Liquid-Cooled Ultra-Precision Ball Screw Assemblies for High-End Industrial Mother Machine Five-Axis CNC Machine Tools" and "High Dust-Proof Ultra-Precision Linear Rolling Guide Assemblies". Benchmarking against world-class international brands such as THK/NSK and Rexroth/Schneeberger, the screw accuracy meets Japan's C0 Class standard, while the guide accuracy complies with Europe's G0 Class specification. These products enable machine tools to achieve a maximum positioning accuracy of 0.0015 millimeters and a repeat positioning accuracy of 0.0009 millimeters, breaking the long-term reliance on imports for rolling functional components in China's top-tier high-precision CNC machine tools.

Currently, under the framework of national major science and technology special project cooperation, the company has established stable supporting partnerships with leading domestic CNC machine tool enterprises including Dalian Kede, General Technology Group, and Jinan No.2 Machine Tool Group. This collaboration has effectively enhanced the independent controllability of China's high-end equipment and strengthened the security of the industrial supply chain.

02 Green Transmission: Empowering Low-Carbon Manufacturing

Against the backdrop of the green transformation of China's manufacturing industry, the company's products have garnered significant attention due to their prominent energy-saving and environmental protection features. For instance, ball screws and linear guides adopt "rolling friction" instead of traditional "sliding friction", achieving a transmission efficiency of over 90% and a service life of more than a decade, thereby substantially reducing equipment energy consumption and resource depletion.

Meanwhile, as the "oil-to-electricity" transition advances in the equipment manufacturing industry, ball screws, as core components of servo electric cylinders, are gradually replacing traditional hydraulic systems. While enabling more precise and efficient transmission, they eliminate environmental pollution caused by hydraulic oil leakage. Their low energy consumption aligns with the direction of the manufacturing industry's green transformation under the "dual-carbon" goals. Their applications in fields such as new energy vehicles, aerospace, and humanoid robots further highlight the broad prospects and people's livelihood value of green transmission technology.

The company's participation in this exhibition is a vivid microcosm of China's manufacturing industry consolidating its foundation and pursuing innovative breakthroughs. During the critical transition period from the 14th Five-Year Plan to the 15th Five-Year Plan, the company will continue to adhere to the deep integration of technological innovation and industrial innovation, and compose a new chapter of self-improvement and green development for China's manufacturing industry on the new journey.
