Ultrasonic cutting is the use of sound energy to cut, do not need a sharp edge, do not need a lot of pressure, will not cause the cutting material edge collapse, damage. Ultrasonic rubber cutter can easily cut resins, rubber, plastics, fabrics as well as a variety of overlapping composite materials and food.

The principle of the ultrasonic rubber cutter is to convert the 50/60Hz current into 20, 30 or 40kHz electrical energy through the ultrasonic generator (also known as the ultrasonic power supply). The converted high-frequency electrical energy is again converted by a transducer into mechanical vibration of the same frequency, which is then transmitted to the cutter through a set of amplitude-modulators that vary the amplitude. The ultrasonic rubber cutter vibrates along its length with an amplitude of 10-70μm, repeated 40,000 times per second (40 kHz) (the vibration of its blade is microscopic and difficult to see with the general naked eye). The cutter then transfers the received vibration energy to the cutting surface of the workpiece to be cut. In this area, the vibration energy is cut by activating the rubber molecular energy and opening the molecular chain of the rubber material.

Advantages of ultrasonic rubber cutting
Very high cutting precision - the cutting is smooth, clear and clean.
Repeat cutting - Blade output is monitored by a closed loop circuit to provide consistent cutting results.
Lower temperature -- Rubber has almost no heat.
Dry - No lubrication, ultrasonic rubber cutter vibrates 20,000 to 40,000 times per second (depending on application), so the cutter head passes smoothly through the rubber.
Low power consumption - the head vibrates only when cutting, requiring about 100 watts or less in typical thin material applications.
Easy integration into automation -- The ultrasonic rubber cutting process is very simple and can be upgraded to existing mechanical structures or installed in new equipment.
