What Is Ultrasonic Machining?

Ultrasonic processing is a special tool that uses ultrasonic frequency to make small amplitude vibrations, and uses the abrasives in the liquid between it and the workpiece to strike the surface to be processed, so that the surface of the workpiece material is gradually broken, which is abbreviated as USM in English. Ultrasonic machining is commonly used for perforation, cutting, welding, nesting and polishing.

With the development of technology, ultrasonic is more and more used by people. He gradually established his position in cutting, wire drawing dies, deep and small hole processing through some characteristics of himself. Ultrasonic machining has developed rapidly in the past few decades, especially in the field of difficult-to-machine materials, it has solved many key process problems and achieved good results. Difficult-to-machine materials have promoted the development of ultrasonic processing technology, thereby further promoting the development of new materials. It can be predicted that the application of ultrasonic processing technology will become more and more widespread ^[1]

In 1927, American physicists Wood and Lumis first performed ultrasonic machining tests, using strong ultrasonic vibration to sculpt and quickly drill glass plates, but they were not used in industry at that time; in 1951, the Cohen system in the United States Became the first practical ultrasonic processing machine.

In the mid-1950s, Japan and the Soviet Union changed

For ultrasonic processing of plastic materials

1. Welding method:

Under moderate pressure, the welding head that vibrates with ultrasonic waves and high frequencies causes frictional welding of the two plastic surfaces and instantaneous fusion bonding. The welding strength is comparable to that of the main body. Using suitable workpieces and reasonable interface designs can achieve watertightness. It is air-tight and eliminates the inconvenience caused by the use of auxiliary products to achieve efficient and clean welding.

two,

Not limited by whether the material is conductive; the tool has a small macro force on the workpiece and a small thermal effect, so it can process thin-walled, narrow and thin workpieces; the greater the brittleness of the processed material, the easier it is to process, the harder or the strength and toughness of the material The larger the size, the more difficult it is to process. Because the removal of the workpiece material mainly depends on the abrasive, the hardness of the abrasive should be higher than the hardness of the material being processed, and the hardness of the tool can be lower than that of the workpiece material; it can be combined with other processing methods. ,Such as

Ultrasonic processing not only overcomes the shortcomings of some special materials that are not easy to be processed, but also improves the processing accuracy, shortens the processing time, and improves the efficiency. And its position in cutting, grinding and finishing is irreplaceable.

New developments in ultrasonic processing technology, such as micro-sonic processing, NC ultrasonic processing technology, etc. The study of these technologies has promoted our research on new materials, which in turn has promoted the development of technology, which has led to the continuous development and improvement of ultrasonic processing technology. Ultrasound processing is not only used in industry, but also in medicine and life. What is widely used in life is the ultrasonic cleaning technology, which helps people solve the problem of difficult cleaning of some items, such as range hoods, watch overall movements, watch bands, etc.

Therefore, it is foreseeable that the ultrasonic processing technology will have unlimited development in the future, and it will continuously cover various fields and industries ^[1] .
