Tuned Mass Damper Vibration Suppression Technology 2026/09/29

Introductions

Machine tool vibrations during cutting process are classified into high and low frequency. High-frequency vibrations can be reduced by adjusting spindle speed, while low-frequency vibrations are caused by structural natural frequencies and often leave marks on workpiece surfaces that require manual polishing. This technology suppresses low-frequency vibrations using resistance generated by relative motion, providing a faster and more effective solution than traditional structural redesign methods.
