Ultrasonic cutting technology is widely used in lightweight construction: Today, many industries view weight reduction as a key driver of innovation. These include automotive technology, aerospace technology, and medical technology. Ultrasonic cutting provides excellent conditions for processing the materials increasingly used in lightweight construction.
Today, interchangeable blades enable the efficient cutting of various materials, such as fiberglass or carbon fiber fabrics, foam materials, leather, synthetic leather, rubber, thick cardboard, or paper.
Ultrasonic frequencies exceed the threshold of human hearing, typically at 20 kHz or higher. The frequencies used for cutting range from 20 kHz to 30 kHz. Ultrasonic waves are generated by a piezoelectric transducer that causes the blade to vibrate at high frequencies; this produces extremely effective results at resonance while requiring relatively low power. Consequently, the cut surfaces are exceptionally clean, even under low thermal load conditions. There is absolutely no risk of material adhering to the blade. Furthermore, this process offers additional advantages, making it particularly suitable for cutting materials used in lightweight structures. Unlike mechanical milling, ultrasonic cutting causes no material loss. There is no debris; the cut edges are smooth and clean, eliminating the need for finishing.
No cutting medium is required for operations such as waterjet cutting. The workpiece remains dry and clean. The cutting depth can be adjusted as needed, and ultrasonic cutting is also quiet. No noise protection measures are required. Furthermore, unlike laser cutting, the surface of the workpiece does not meet specific quality standards; there are no charred edges or combustion gases. Due to its extremely low acquisition and operating costs compared to other processes, ultrasonic cutting has become a practical solution for numerous lightweight structural applications.
