The DMS Ultrasonic Mill from DMG is available in 3, 4 and 5 axis machines specifically for the milling of advanced materials. In comparison to conventional methods the patented DMG Ultrasonic system leads to a 5-fold productivity increase, less material stress, longer tool life and at the same time improved surface quality with higher flexibility for machinable work piece geometries.

The DMS Ultrasonic by DMG offers drilling, milling and grinding operations on one machine and in some cases at one time. Here’s how it works.

• The Ultrasonic-generator is sending an electrical impulse / signal to the Ultrasonic spindle.
• This electrical high-frequency signal gets transformed into a mechanical movement in the inner spindle (1-3 µ Amplitude).
• A special developed booster amplifies the oscillating amplitude to the machining tool (3-50 µ Amplitude).
• The conical tool holder („K“ system) guarantees a force- and positive-fit connection and a 100% transfer of the oscillation from the booster to the diamond tool.
• The diamond tool is expanding and contracting in a pulsating manner (approx. 20.000 times in a second )
• Due to this vibration the diamond grains of the tool are „smashing“ into the surface of the workpiece – destroying the material into small particles
• The main stock removal rate is achieved at the top of the working tool, because of the oscillating vibration in vertical direction.
• The simultaneous rotation of the tool guarantees the flushing of the removed material out of the working zone and a consistent wear of the tool.

• The intelligent control algorithms Adaptive Control (ADC) and Acoustic Control (ACC) guarantee a continuous process monitoring due to the processing of
  measured physical values during the machining.
• The automatic regulation of valuables during the machining (feed, rpm,…) underwrites a frictionless machining sequence.

• ADC processes the active spindle torque (Nm), ACC processes an acoustic echo-signal (V), that is reflected by the work piece

• ADC monitors the cutting forces - ACC should be used, if the best possible surface finish is requested!
