Mass finishing basics

What is mass finishing ?

Mass finishing also called trovalisation, vibropolishing, tumbling or microfinition, incorporates techniques such as polishing , deburring

Mass finishing was inspired by natural phenomena :

Regular flow of water from a river or the ebb and flow of the sea turns rough stones into pebbles perfectly polished.


The needed ingredients are in these processes :

  • Abrasive chips (ceramic, Porcelain, plastic, metal)
  • Liquid compounds or pastes
  • Equipment (vibrators, centrifuges…) that generate movements between the chips and parts.
  • quality water adapted to the process


The parts to be polished or deburred are introduced into a chamber that contains abrasive ; this chamber is set in motion (vibration or rotation).

The removal of material, quality of polishing and the surface state depends on the composition and size of the chips; as well, speed settings and cycle time are fundamental.

Our technical laboratory-team is available to assist you reactively.

Polishing, deburring, radiusing, deoxidation, smoothing, degreasing, sandblasting, blasting, surface cleaning, descaling, correspond to the different possible applications of this method using friction between the chips and parts .
