Technical Paper of the Abrasive Processing Society
Supporting ultra-precision and fine processing peripheral technologies! Introducing the multi-speed and multi-surface method, which is a balance correction method.
This technical document introduces a new balance correction method for high-speed spindles (multi-speed, multi-surface method). It discusses the effectiveness and impact of the multi-speed, multi-surface method based on case studies, as well as explaining the classification of rotors, which is a crucial point for balancing rotating bodies (rotors), and the concept of critical speed. 【Contents】 ■1. Introduction ■2. Rotors and Critical Speed ■3. Conventional Balance Correction Methods ■4. Development of the Multi-Speed, Multi-Surface Method ■5. Field Balancer for Elastic Rotors ■6. Conclusion ■7. References *For more details, please refer to the PDF document or feel free to contact us.

Sigma's balance measurement method features the adoption of multivariate analysis techniques for detecting imbalances, allowing for high-precision measurements across a range from low to ultra-high rotational speeds. The field balancer that incorporates this measurement method has been in use since 1985, with cumulative production exceeding 8,000 units. Furthermore, after that, we began selling more precise balancing machines and condition monitoring devices that continuously monitor rotating machinery and detect signs of abnormalities, which also utilize the aforementioned measurement method. Over 30 years since the start of balancer production, Sigma's balancers are actively used across various industries.
