Ultrasonic cleaning machine is using ultrasonic in the liquid cavitation effect, will produce a large number of non-stable small bubbles shaking growth, closing movement, causing a strong collision between liquid particles and forming a local point of extreme high temperature and high pressure, on the work internal holes, blind holes within the dirt to rapid stripping and cleaning effect.
