The quality requirements of the workpieces are also getting higher and higher. The cleaning of the workpieces has become a major focus. In the past, cleaning was mostly done manually, and manual water blowing and drying were used, which was not clean and inefficient. There were also ultrasonic cleaners for cleaning. Ultrasonic cleaning is the direct and indirect effect of ultrasonic cavitation, acceleration, and straight flow in the liquid on the liquid and dirt, so that the dirt layer is dispersed, emulsified, and peeled off to achieve the purpose of cleaning.
