At Gakusho Co., Ltd., we perform precision and fine processing of high-hardness brittle materials such as ceramics, glass, sapphire, zirconia, and single crystal silicon, which are difficult to process using conventional methods, by utilizing ultrasonic processing technology. Ultrasound is used in various fields such as fish finders, radar, sensors, and cleaning. Here, we will introduce what ultrasound is, the effects it brings, and how it enables precision and fine processing. 【What are sound waves?】 Sound waves are "waves transmitted by vibrating objects to their surroundings." Sound waves are generated when a sound source vibrates. 【What is ultrasound?】 Generally, ultrasound refers to high-frequency sound waves that are outside the audible frequency range for humans. In specialized fields such as engineering, it is recognized as "sound waves not intended to be heard by the human ear" and "sound waves that can be applied to certain tasks." In other words, generating ultrasound means that high-frequency vibrations are produced, which can be applied to precision and fine processing.
