[Technical Document] A New Balancing Method for High-Speed Spindles

A detailed explanation of the effects of introducing speed and multi-faceted methods, as well as ultra-precise balancing techniques.

This technical document introduces a new balancing correction method for high-speed spindles. In February 2002, we successfully commercialized the "Field Balancer" incorporating the multi-speed and multi-plane method. As a result, we reduced vibrations across the entire operating range to less than one-fifth of that achieved by conventional technology, and further shortened the balancing time to less than one-eighth. Here, we will discuss the effectiveness of the multi-speed and multi-plane method and provide application examples. [Contents (partial)] ■1. Introduction ■2. Classification of Rotors ■3.
