Handheld Ultrasonic Rubber Cutter

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 cutter transfers the received vibrational energy to the cutting face of the workpiece to be cut, in which the vibrational 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 rubber compound

-- Good surface finish and good bonding performance

-- Easy to apply to automated production

-- Fast, efficient, no pollution

Cutting on the upper tread with a 20 kHz cutter (cross and slit)

-- Appropriate amplitude and feed speed for improved cut quality

-- The key factors affecting the cutting blade are the angle of the knife, the size, the shape and the thickness

-- High power, more suitable for tread cutting of high-class 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 (usually 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, the shape and the thickness

-- Suitable for inner lining and sidewall cutting of semi-steel tires, radial tires, etc.

-- Commonly used cutter types: 82.5mm, 120mm, 170mm, 190mm, etc.
