Several operations can be performed to finish metals, metal tumbling is one of them.
Finishing and smoothing with metal tumbling: materials and machinery of the process
How does the tumbling
It is in fact a real finishing, which has the important consequence of giving surfaces an extremely uniform appearance.
The machine responsible for this process is the buratto. The structure is nothing more than a large industrial washing machine where the basket is not round but hexagonal so that by rotating it not only makes the inserted pieces roll, but raises them and then makes them fall on the side of the next hexagon.
The walls of the basket are covered with vulcanized rubber that absorbs very well the blows of the falling pieces by making them bounce between them.
This roll of the pieces combined with other small spherical bodies inserted specifically to increase the abrasive effect of the operation, involves the elimination of burrs, sharp edges, calamine and rust, leaving the pieces uniform and shiny, displaying the metal in its natural shine.
This process is widely used on small to medium sized parts where manual cleaning would involve hours of work not achieving the same result.
The machines Tecnos has at its disposal are all of the latest generation, and allow to work on cut parts of different sizes.
The work of these cutting-edge machines is also supervised by our team of technicians, who are also responsible for the correct setting of the machines in order to obtain the perfect result, just according to the customer’s needs.
