A Tool Holder with Massive Appeal

The Self-Tuning Mass Damper™ (STMD™) features a tungsten carbide mass inside the tool. The mass is supported by polymer discs that have frequency-dependent stiffness. As cutting forces are applied to the tool, vibration occurs on a frequency band. To counteract such movement, the MAQ STMD™ self-adjusts to that frequency to maximize the mass damping effect.

The STMD™ is available in more than a dozen length-diameter combinations, as the table shows. To determine which product is right for you, view our Application Guide or our 2019 Catalogue.
