Ultrasonic cutting processes for lightweight construction: Today, many industries are using weight reduction as a driver of innovation. This mainly includes automotive technology, aerospace technology and medical technology. Ultrasonic cutting provides a good prerequisite for the processing of increasingly large amounts of materials in lightweight construction.
Today, the interchangeable cutting edge enables efficient cutting of different materials, such as fiberglass or carbon fiber fabrics, foam, leather, artificial leather, rubber, cardboard or paper.
The ultrasonic wave frequency exceeds the hearing threshold, about 20kHz or more. The frequencies used for cutting are in the range of 20 kHz to 30 kHz. Ultrasonic waves are generated by a piezoelectric transducer that vibrates the cutting edge at high frequencies, which is extremely effective in resonance and requires less power. Therefore, when the heat load of the environment is low, the slices cut out are neat. There is no need to worry about adhesion to the product on the cutting edge. In addition, this process has other advantages, making it particularly suitable for cutting materials used in lightweight construction. Compared to mechanical milling, ultrasonic cutting does not produce any material loss. No debris; The cut edges are smooth and clean, so no trimming is required.
There is no need to use cutting media for operations such as water flow cutting. The cut will also be kept dry and tidy. The cutting depth can be adjusted arbitrarily, in addition to this, ultrasonic cutting is also less noisy. No noise protection measures are required. In addition, unlike laser cutting, the surface of the cut object cannot meet special quality assessment standards; No burnt cutting edges or combustion gases will form. Due to its extremely low acquisition and operating costs compared to other processes, ultrasonic cutting is a practical process for many lightweight construction applications.
