Ultrasonic cutting processes commonly used in lightweight structures: Nowadays, many industries regard weight loss as a driving force for innovation. It mainly includes automotive technology, aerospace technology and medical technology. Ultrasonic cutting provides good prerequisites for the processing of increasing amounts of materials in lightweight structures.
Today, effective cutting of different materials can be achieved through replaceable blades, such as fiberglass or carbon fiber fabrics, foaming materials, leather, artificial leather, rubber, thick cardboard or paper.
The wave frequency of ultrasonic waves exceeds the hearing threshold, about 20kHz or above. The frequency used for cutting is in the range of 20 kHz to 30 kHz. Ultrasonic waves are generated by a piezoelectric transducer that vibrates the blade at high frequency, which has a very strong effect in resonance and requires a small power. Therefore, when the ambient thermal load is low, the cut slices are very neat. There is no need to worry about sticking to the blade. Furthermore, this process has other advantages and is therefore particularly suitable for cutting materials used in lightweight constructions. Ultrasonic cutting does not cause any material loss compared to mechanical milling. No debris; the cutting edges are smooth and clean, so there is no need for trimming.
There is no need to use a cutting medium when performing operations such as water flow cutting. The cuts will also be kept dry and tidy. The cutting depth can be adjusted arbitrarily, and in addition, the noise of ultrasonic cutting is also small. No protection against noise is required. In addition, unlike laser cutting, the surface of the cut object cannot meet the special quality assessment criteria; no burnt cutting edge or combustion gases will be formed. Due to its extremely low purchase and operation costs compared to other processes, ultrasonic cutting has become a practical process required for many lightweight structural applications.
