Layers of burnt oil and other solid contaminants (oxides and lapping and polishing pastes) stuck to the part, on the other hand, require the action of an ultrasonic system, which can be installed on request in the majority of closed-circuit systems.
When the ultrasonic energy is transmitted to the solvent, its action is reinforced and detachment of the pollutants stuck to the surface of the part is made easier, thanks to the cavitation action that rapidly produces thousands of small bubbles that implode on the contaminant, making it crumble.
