The cleaner would first inspect the jewelry to ensure that the gemstones are accounted for and secured. Materials that can handle it are often placed in an ultrasonic bath using a cleaning solution and later put through a steam cleaner, while more sensitive materials will go through light brushing in soapy water.
In chemical-assisted ultrasonic machining (CUSM), a chemically reactive abrasive fluid is used to ensure greater machining of glass and ceramic materials. Using an acidic solution, such as hydrofluoric acid, machining characteristics such as material removal rate and surface quality can be improved greatly compared to traditional ultrasonic ...
Adamant Namiki uses integrated manufacturing, handling its products from the raw material, to processing, through to polishing. Industrial jewels, such as diamond, sapphire, and ruby, are used for jewel bearings, sapphire substrates, [4] [5] exterior watch parts, semiconductor wire bonding capillaries, nozzles, LTCC [6] (Co-fired ceramic) and so on.
Laser ultrasonics is a contactless ultrasonic inspection technique based on excitation and ultrasound measurement using two lasers. A laser pulse is directed onto the sample under test and the interaction with the surface generates an ultrasonic pulse that propagates through the material.

Ultrasonic impact treatment (UIT) is a metallurgical processing technique, similar to work hardening, in which ultrasonic energy is applied to a metal object. This technique is part of the High Frequency Mechanical Impact (HFMI) processes. Other acronyms are also equivalent: Ultrasonic Needle Peening (UNP), Ultrasonic Peening (UP).
The ultrasonic thickness gauge then calculates the data based on the speed of the sound through the tested sample. The first ultrasonic thickness gauge was made in 1967 by Werner Sobek; [citation needed] a Polish engineer from Katowice. This first ultrasonic thickness gauge measured the velocity of the waves it emitted in particular test ...
