Ultrasonics, I.e. High frequency vibrations, generate agitation in liquid resulting into " Cavitation", which is rapid formation and collapse of minute bubbles in liquid. Implosion of bubbles with high pressure on exposed surface of component dislodges and removes contamination like dirt, dust, oil, grease, chips, wax, lapping paste, carbon etcs. it helps in cleaning of inaccessible areas. Very high degree of cleaning can be achieved in multi chamber/multi-operation cleaning system with proper orientation on the components, filtration of cleaning liquid, rinsing & drying of parts with air and/or vacuum.
