come in contact with a surface, they strip away any contaminants on it and fush them away. Tis aggressive cleaning action can cut cleaning time by as much as 90 percent. Te oscillator system is available with rod, immersible and plate-form transducers, as well as ultrasonic units that work with individual elements. Correct Chemical Agent Te basic chemical principle, "Like dissolves like," should be applied when determining the best cleaning medium for a given application. In other words, when working with a mineral-oil-based (non-polar) cooling lubricant, such as machining oil, grease or wax, a solvent is generally the right choice. Once the oil is removed, chips and particles lose their grip on the surface and are cleaned away ultrasonically. For water-based (polar) contaminants such as coolant and lubricant emulsions, polishing pastes, additives, salts, wear particles and other solids, water-based cleaning agents are generally used. Tey are available in pH-neutral, alkaline and acid form. To ensure that the cleaning agent will not attack the workpiece, cleaning trials should be performed with the manufacturers of the cleaning medium. Determining the Optimal Frequency :: Ultrasonic cleaning efciently, rapidly and reliably meets the increasingly stringent cleanliness requirements for applications such as medical implants.

The modular construction allows precise adaptation to the specifc cleaning task.

In general, the lower the frequency, the larger the cavitation bubbles and the greater the energy released from the bubbles. A low frequency, therefore,
