After turning, milling, drilling or grinding, it is important to remove impurities on the surface of the workpiece, for example chips and residues of cooling lubricants, grinding and polishing agents. Ultrasonic cleaning cleans gently and thoroughly and is also suitable for complex component geometries and workpieces with hard-to-reach areas such as cavities, boreholes and threads. For this purpose, the workpiece is immersed in an ultrasonic bath. The sound waves in the range from 20 kHz to 4 MHz cause the liquid to vibrate, thus loosening even firmly adhering contaminants by overcoming the adhesive forces.
Ultrasonic cleaning produces an excellent result and is suitable for metals such as aluminum or stainless steel and a variety of other materials. Used parts can be reconditioned by ultrasonic cleaning, as even stubborn dirt such as lime or combustion deposits are removed.
