3. Third-generation ultrasonic cleaning technology
Let me now discuss ultrasonic cleaning, the backbone of the new technology. The principle is important, and the applications are unlimited, depending on the object. This is the basic technology that was first discovered and put into practical use by the author in the world during the CFC era, and has been refined under the banner of “eliminating CFC” and developed into today’s ultra-strong cleaning, ultrasonic burr, ultrasonic polishing, and ultrasonic high-speed etching (presented by the author at the 1993 Washington International Conference). （Without precise cavity control, this cleaning technology will not produce the required performance, and in some cases will lead to the destruction of the ultrasonic transducer and a significant reduction in cleaning power. However, without this technology, we believe that the new era of cleaning innovation, so-called precision cleaning technology, etc., would be impossible.
The method of controlling the content of gas dissolved in the liquid to maximize and utilize the impact force of cavities generated by ultrasound is called the third-generation cleaning technology cavitation enhancement system.
