03. INTRODUCTION
The principle of ultrasonic cleaning
Ultrasonic cleaning is based on the cavitation effect caused by

Microscopic bubbles are formed.These implode causing the cavitation

which create an intense scrubbing action on the surface of the item
being cleaned. The bubbles are small enough to penetrate microscopic
crevices, cleaning them thoroughly and consistently.

Ultrasonic cleaning is extremely effective in removing dirt and grime
which would normally require tedious manual cleaning . It is used to
clean a wide variety of instruments and mechanical parts such,
returning them to almost “like new” condition without damage to
delicate parts.
