Universal application of ultrasonic cutting processes for lightweight structures: Today, many industries are using weight reduction as an innovation driver. These include, among others, automotive technology, aerospace technology and medical technology. Ultrasonic cutting offers good prerequisites for the processing of materials that are increasingly used in lightweight construction.

Nowadays, interchangeable blades enable the efficient cutting of different materials such as fibreglass or carbon fibre fabrics, foams, leather, synthetic leather, rubber, thick cardboard or paper.

Ultrasound waves have a frequency above the threshold of hearing, around 20 kHz and above. 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 blade at a high frequency, which is extremely effective in resonance and requires less power. As a result, the slices are neatly cut when the thermal load of the environment is low. There is no need to worry about product adhering to the blade. In addition, this process has other advantages that make it particularly suitable for cutting materials used in lightweight construction. In contrast to mechanical milling, ultrasonic cutting does not cause any material loss. There are no chips; the cutting edges are smooth and clean and therefore do not need to be trimmed.

There is no need to use a cutting medium for operations such as water jet cutting. The cut remains dry and clean. The depth of cut can be adjusted at will, and in addition, ultrasonic cutting is quiet. No noise protection is required. In addition, unlike laser cutting, the surface of the cut object does not fulfil special quality assessment criteria; there are no burnt cutting edges or burning gases. Due to its extremely low acquisition and operating costs compared to other processes, ultrasonic cutting has become a practical process required for numerous lightweight structural applications.
