Milling Tools that Help You Remove Material Faster

MAQ has taken the Self Tuning Mass Damper™ (STMD) technology to milling tools.

The milling tool holders contain a tungsten mass supported by polymer discs, which have a frequency-dependent stiffness. The mass dampers have a self-tuning function that help you overcome vibrations caused by:

  • Use of multiple inserts on a single tool holder, for high feed rate per rotation
  • Tooth passing frequency matches the resonance frequency
  • Long reach of a milling tool that requires L/D ratios over 4

The STMD is available in a variety of L/D ratios that allows the milling arbor to be automatically tuned to a changing frequency when the machine spindle changes coordinates or speeds. The result is an optimal vibration dampening of the milling tool.

By using our STMD milling holders, you can double the number of cutting edge comparing to a conventional holder, and reduce the cycle time by 50% while maintaining the same cutting data (feed per teeth and speed). You will also get a better surface finish as well as meet tougher tolerance requirements.

For a better understanding of how we can help you meet your milling needs, see our Application Guide or tell us about your specific requirements.

According to tests conducted at a leading machine tool builder in March 2018, the MAQ STMD™ showed significantly less displacement than other tool holders and demonstrated superior versatility with respect to speeds, feeds, depth of cut and LD ratio.
