Mass finishing basics

What you always wanted to know about mass finishing

technical solutions for tribofinishing polishing


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

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


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

The removal of material, quality ofpolishing and the surface condition obtained depend on the composition and size of the media; as well, speed settings and cycle time are fundamental.

Our technical team with its test laboratory composed of more than 40 different equipment is at your disposal to assist you reactively.

Polishingdeburring, 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 .
