Chatter-Free Tooling

 

Chatter-Free Tooling TM

We are pleased to introduce the answer for metal cutting applications limited by chatter, vibration, tool overhang, tolerance and surface finish. 

Applications

Benefits
  • Stationary or rotating
  • Increased DOC and MRR
  • Boring and milling
  • Eliminates chatter
  • Lathes, machining centers, transfer lines
  • Enables longer tool overhang
  • Continuous or interrupted cuts
  • Improves surface finish
  • Specialty tooling
  • Reduced dynamic variation

 
  • Tunable adjustment

Internal or modular add-on tuned damping technology provides optimal dynamic stability of tools yielding significant machining performance improvement and increased profitability.  Standard tools and customized solutions are available for your most demanding machining needs.

Chatter-Free Tooling TM reliably outperforms standard and carbide tooling through tuned damping technology by suppressing the tools natural vibration response.   Chatter-Free Tooling TM provides stable machining at longer overhang and deeper DOC and minimizes vibration due to surface interruptions, entry and exit.

HOW DOES IT WORK?

Each tool contains a passive damping device that is dynamically tuned. The tuning process establishes the tools frequency and then positions the damper so the bar’s frequency is constantly out of phase. In the out of phase condition, the dampeners motion is used to suppress the bars vibration or tendency to chatter. In essence, the energy in the system is absorbed by the damper and not released by the tool in the form of chatter.

Typical Bar Design

 

Dampening Test Comparison

As shown below, by accelerometer testing, a standard carbide bar will vibrate at it’s natural frequency significantly longer than a “Tuned” CFT bar. The increased damping allows for greater depth’s of cut without chatter and reduced vibration in interrupted cutting. (please see results in demo video)
