Industrial Ultrasonic Cutter: Precision Cutting for Hard & Delicate Materials

The principle of ultrasonic rubber cutting
  Ultrasonic cutting utilizes the energy of sound waves for cutting, eliminating the need for sharp blades or significant pressure, and preventing chipping or damage to the material being cut. Ultrasonic rubber cutting knives can easily cut resins, rubber, plastics, fabrics, and various overlapping composite materials and foods.

  The principle of ultrasonic rubber cutting knives involves converting 50/60Hz current into 20, 30, or 40kHz electrical energy using an ultrasonic generator (also known as an ultrasonic power supply). The high-frequency electrical energy is then converted back into mechanical vibrations of the same frequency through a transducer. These mechanical vibrations are transmitted to the cutting blade via an amplitude modulator that can adjust the amplitude. The cutting blade vibrates along its length at an amplitude of 10-70μm, repeating 40,000 times per second (40 kHz) (the vibration of the blade is microscopic and generally difficult to see with the naked eye). The cutting blade transfers the received vibrational energy to the cutting surface of the workpiece, where the energy cuts the material by activating rubber molecules and breaking molecular chains.
