Process Mechanical surface cleaning process where the workpiece immersed in water is subjected to a high voltage such that shock waves are formed and clean its surface.
Process Polishing process in which the workpieces are placed in a liquid containing detergent and small ferromagnetic needles which is rotated by externally applied magnetic fields.
Process Mechanical surface cleaning process where the workpiece is immersed in a solvent, which is exposed to ultrasonic waves resulting in cavities implodes on the surface which cleans the workpiece.
