Ultrasonic cutting application

How Ultrasonic Cutting Works
　The principle of ultrasonic cutting is to convert a 50/60 Hz current into 20, 30 or 40 kHz of electrical energy by means of an ultrasonic generator. The converted high-frequency electrical energy is again converted by the transducer into mechanical vibration of the same frequency, and then the mechanical vibration is transmitted to the cutting blade through a set of amplitude modulator devices that can change the amplitude. The cutting blade transmits the received vibration energy to the cutting surface of the workpiece to be cut, in which the vibration energy is cut by activating the molecular energy of the rubber molecule and opening the molecular chain.
　The main components of a set of ultrasonic cutting systems include ultrasonic generators, transducer/amplifier/cutter triplets and various cables.
　Advantages of ultrasonic tire rubber cutting
　-- High cutting precision, no deformation of the compound
　-- Good surface finish and good bonding performance
　-- Easy to apply to automated production
　-- Fast, efficient, non-polluting
　Cutting on the upper tread using a 20 kHz cutter (cross cut and slit cut)
　-- Appropriate amplitude and feed speed for improved cutting quality
　-- The key factors affecting the cutting blade are the angle of the knife, the size, shape and thickness of the knife
　-- High power, more suitable for tread cutting of premium cars and racing cars
　-- Commonly used cutter types: 200mm, 300mm, 355mm, 470mm, etc.
　Cutting the sidewall of the tire rubber with a 40 kHz cutter (generally using a cross-cut method)
　-- Cutting speed depends on the angle and thickness of the rubber of the cutting tire
　-- The key factors affecting the cutting blade are the angle of the knife, the size, shape and thickness of the knife
　-- Suitable for inner lining and sidewall cutting of semi-steel tires, radial tires, etc.
　-- Commonly used cutter types: 82.5mm, 120mm, 170mm, 190mm, etc.
