Mass finishing
at a glance

Mass finishing, also known as trovalization, vibroabrasion, barrel polishing or vibropolishing, is a chemical-mechanical surface treatment process used to modify the surface of a variety of industrial parts. The technique is constantly evolving, making it an indispensable solution in modern industry.

Good to know: Mass finishing is known as surface finishing or mass finishing.

Mass finishing was inspired by natural phenomena that exist in nature, such as the friction of sand and water, allowing rocks and pebbles to be polished naturally, giving them smooth, shiny surfaces. Today, this industrial biomimetics is optimized by cutting-edge technologies.

The modern Mass finishing process

The aim of the Mass finishing is to reproduce this natural phenomenon on an industrial scale by combining different elements:

  • Specialized equipment (machines from Mass finishing)*
  • Water (with ecological recycling systems)
  • From abrasives new-generation abrasives (3 optimized types)
  • Chemical additives (eco-responsible formulations)
  • Digital control systems (new for 2024)

*FINISHTECH offers you 7 ranges of Mass finishing machines in different ranges, all equipped with the latest technological innovations.

How do I start a treatment cycle at Mass finishing?

There are several stages:

  • Step 1: The operator uses the PLC display to switch on the machine.
  • Step 2: Next, he opens the barrel cellar and deposits the abrasives manually or automatically.
  • Step 3: It then loads the parts in turn, either manually or automatically.
  • Step 4: Then fill the tank or barrels with the volume of water and chemical additive
    required for the process, and close the hood.

It should be noted that during treatment, the volume of water and chemical additive is automatically dosed via a swivel hose according to the cycle selected in the machine’s PLC from Mass finishing.

  • Step 5: The operator sets the execution time and starts the cycle.
  • Step 6: At the end of the treatment process, before opening the barrels or the treatment tank to recover the treated parts, in the case of a high-energy centrifugal machine, the operator must engage the pressure release system to ensure that there is no pressure when opening.
  • Step 7: Once this operation is complete, the operator can empty the tank.
  • Step 8: The sieving grid then separates the parts from the abrasives, sending each element to the appropriate hoppers (this step may differ depending on the processing machine used).
  • Step 9: Finally, if any fragile parts are present, the operator must manually remove
    them from the barrels.

Our commitment to quality

The Mass finishing is an industrial process that requires a number of decisive factors to obtain good finishing results, including know-how and the right methodology.

It’s not enough to deburr or polish parts to achieve a good finish, but it’s essential to apply the appropriate methodology and rigor.

By following the protocol to the letter, and with perseverance, you’ll be able to achieve highly qualitative results, and above all results that will be reproducible with each cycle.

Finally, bear in mind that your choice of abrasives and chemical additives is directly linked to the results you’ll obtain, so choose wisely to avoid any unpleasant surprises.
