Ultrasonic Polishing System

The Ultrasonic Polishing Equipment you can rely on!


The Ultrasonic Polishing System is the new and improved polishing system from Diprofil and its main advantage is its very short stroke length (10-35 µm) which has a very high frequency (18-25 kHz). This makes this equipment ideal for working in narrow and confined spaces such as cavities and slots, where a short stroke length is preferable. 

For this kind of delicate work, the Diprosonic DUS-300 will give you precise finishing with rapid stock removal in a relatively clean environment without the need for lubricating fluids for example.


The Ultrasonic Polishing System is excellent for use together with Ceramic fibre stones and Sintered diamond files, but it is also possible to use with Electroplated diamond files, as long as the shank of the used tool is kept as short as possible.

Main features:

  • Operated by hand or by foot-switch
  • Automatically finds the right frequency for each tool
  • 36W max output
  • Two output levels (high/low)
  • Capable of long working periods
  • Auto feedback system
  • Small, compact and low weight
