The first successful domestic development of a high-end, high-precision automated balancing machine capable of automatically and accurately measuring and correcting minute mass imbalances in rotating components has been achieved. This achievement is particularly significant in that equipment classified by Japan as a strategic material essential to key national manufacturing industries has been developed using domestic technology and successfully commercialized through deployment in actual industrial production environments.
Dr. Byeongock Kim, Principal Researcher at the AX Convergence Research Center of the Virtual Engineering Platform Research Division, Korea Institute of Machinery and Materials (KIMM, President Seog-Hyeon Ryu), under the National Research Council of Science & Technology (NST; Chairman Young-Sik Kim), in collaboration with P&S Co., Ltd. (CEO Bong-Soo Park), has developed the core technology for a high-precision automated balancing machine. This technology is the outcome of two projects which have been supported by the Ministry of Trade, Industry and Resources (MOTIR) since 2020.
The research team focused on achieving the repeatability and durability required in real industrial environments and implemented an intelligent architecture that enables the equipment to autonomously diagnose its own condition and manage measurement accuracy. As a result, the reliability of equipment performance and repeatable precision were comprehensively enhanced, and an automated balancing machine technology directly applicable to production lines was successfully developed.
A balancing machine measures mass imbalance in rotating components and corrects it to within the tolerance limits specified by the international standard ISO 21940-11. Conventional foreign systems largely rely on manual or semi-automated operation and primarily focus on measurement and correction functions, which limits overall system…
