Ultrasonic cutting for lightweight structures: Today, weight reduction is used as a driver of innovation in many industries. It mainly includes automotive technology, aerospace technology and medical technology. Ultrasonic cutting provides good prerequisites for the processing of increasingly used materials in lightweight structures.
Today, the interchangeable blades enable efficient cutting of different materials, such as fiberglass or carbon fiber fabrics, foams, leather, artificial leather, rubber, thick cardboard or paper.
The wave frequency of ultrasound exceeds the hearing threshold, about 20kHz or more. 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 a high frequency, which is extremely effective in resonance and requires less power. Therefore, when the heat load of the environment is low, the cut slices are very neat. There is no need to worry about the product sticking to the cutting edge. In addition, this process offers other advantages that make 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 there is no need for trimming. There is no need to use cutting media for operations such as water flow cutting. The cut will also remain dry and tidy. The cutting depth can be adjusted arbitrarily, and in addition, the noise of ultrasonic cutting is also low. No noise protection is required. In addition, unlike laser cutting, the surface of the cut object cannot meet special quality assessment standards; No scorching cutting edges or burning gases will form. Due to its extremely low acquisition and operating costs compared to other processes, ultrasonic cutting is a practical process required for many lightweight structural applications.
