Equipment start-up time
Due to the need for narrow blade design, the design and manufacture of ultrasonic cutting tool heads is challenging. Vibrating the cutter head with maximum amplitude without load can sometimes cause the cutter head to fail prematurely. Therefore, the signal emitted by the ultrasonic generator should be synchronized with the automated machine, so that the knife head can fully vibrate before the knife edge contacts the food. Vibration before contact is necessary to avoid deformation of the food, which can be caused by contact with non-vibrating cutting surfaces.
Vibration amplitude
The term "amplitude" describes the microscopic displacement of the vibration of the cutting surface of the tool head. The amplitude is mechanically adjusted by the ultrasonic horn, and digitally adjusted by the ultrasonic generator. The amplitude will affect the cutting process and must be adjusted to suit the needs of each application.
Cutting speed
The speed at which the ultrasonic cutting knife enters and advances through the material being cut is also a process variable and should be adjusted for each cutting process. Sometimes it is necessary to slowly penetrate the shell of the product to avoid deformation, and then increase the speed of the cutter in the product to achieve the best cutting effect.
End time of vibration
Depending on the consistency of the material to be cut, after the ultrasonic vibration is turned off, the completed slice may tend to stick to the side of the cutter. Therefore, the ultrasonic vibration can be maintained when the tool head is taken out of the product, and the cutting blade can be released more cleanly and uniformly using the frictionless characteristic.
