Self-Tuning Mass Damper



MAQ's self-tuning mass damper is designed to eliminate costly vibration using a tungsten mass inside the tool. Available in more than a dozen L/D combinations, it helps parts manufacturers, machine tool builders and cutting tool manufacturers reduce cycle time.

A tungsten mass in the MAQ self-tuning mass damper is supported by polymer discs that have frequency-dependent stiffness. As cutting forces are applied to the tool, vibration occurs. To counteract such movement, the tool self-adjusts to that frequency to maximize mass damping.

"These images show that the MAQ STMD offers enhanced performance compared to the most widely used toolholders," said a company spokesperson.

MAQ, a Stockholm-based developer of technologies that simplify machining by eliminating costly vibration, has recently introduced the self-tuning mass damper (STMD). This toolholder features a tungsten mass inside the tool. It is available in more than a dozen length-diameter combinations. "By using the STMD, parts manufacturers, machine tool builders and cutting tool manufacturers can reduce cycle time and cost of ownership by 30%, decrease tooling costs by 5-10%, cut energy consumption by 2-3% and curtail scrap output by 1-2%," said a company spokesperson.

"The STMD is totally plug & play, and maintenance free," said Dr. Qilin Fu, MAQ's CEO and a co-founder of the company. "The STMD technology enables automatic tuning of the mass dampers, without using complex mechatronic systems. It also minimizes the need for tooling changes and is a cost-effective alternative to complex de-vibe tools that require manual adjustment. Given the high volume of machining operations, even the smallest percentage reductions can result in substantial savings."

How It Works

The tungsten mass is supported by special 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.

"According to tests conducted at a machine tool builder, the MAQ STMD showed significantly less displacement than other toolholders and demonstrated increased versatility with respect to speeds, feeds, depth of cut and L/D ratio," said the spokesperson.
