Akira Seiki utilizes key technologies in the development of Productive Type Spindles. They employ the latest inspection equipment from Japan, including a 3D coordinate machine, balance test, online dynamic balance control, and roundness test machine, to thoroughly inspect each high-quality spindle and ensure the best balance performance for longevity. Artificial intelligent thermal control is applied to the internal spindle to regulate the appropriate load rigidity across different speed ranges. For a long spindle life, all Akira Seiki Productive Type Spindles are designed to have low inertia, greatly enhancing high-speed machining capabilities.
