The remarkable progress of technology over recent years cannot be overstated. Tasks that once required extensive manual labor can now be accomplished in mere moments, thanks to innovative devices like ultrasonic cutters.
Ultrasonic cutters utilize a blade that vibrates at an extremely high frequency, surpassing the upper limit of human hearing, which is around 16–20,000 Hz. Frequencies beyond 20,000 Hz fall into the ultrasound range, and this is the operational frequency for ultrasonic cutters.
How do they function?
The process begins with an ultrasonic generator, which transforms energy from a power source or battery into a high-voltage, high-frequency signal. For instance, it might change 12 V to 1500 V, oscillating at a frequency of at least 20,000 Hz. This rapid on-and-off switching occurs at ultrasonic frequencies.
The signal is then relayed to an ultrasonic transducer, a crucial component in the cutter. The transducer changes high-frequency electrical signals into mechanical movements, utilizing piezoelectric ceramic rings that expand when electrified. This means if the transducer receives 20,000 electrical pulses per second, it will execute 20,000 tiny movements in that same timeframe. The system also includes a booster, enhancing acoustic resonance. Typically, this booster is connected to a blade or tip, but in our design, mimicking a traditional knife, we connected the blade directly to the transducer, omitting the booster.
Applications of ultrasonic cutters:
These cutters are primarily found in industrial settings and the food industry, often as large robotic arms or machines designed for swift and efficient cutting of foods or materials.
Benefits of ultrasonic cutters:
The ultrasonic cutting method offers significant advantages, particularly in the industrial and food sectors. It provides quick, precise cuts with minimal effort. Ultrasonic cutters excel at slicing through tough or brittle materials without deformation and with minimal waste. Moreover, the vibrations reduce material adherence to the blade, keeping it clean.
