The difference between traditional cutting knife and ultrasonic cutting knife

Ultrasonic cutting is a kind of ultrasonic equipment specially used for cutting, and it is one of the important categories of ultrasonic applications. Ultrasonic cutting, through the action of ultrasonic waves, causes the grinding wheel blade to generate instantaneous telescopic vibration in the radial direction, which can cause repeated collisions between abrasive grains and processed objects under high acceleration in a very short time.

The principle of ultrasonic cutting is completely different from traditional cutting. Ultrasonic cutting uses the energy of ultrasonic waves to heat and melt a part of the material to be cut, so as to achieve the purpose of cutting the material.

The difference between traditional cutting and ultrasonic cutting machine:

Traditional cutting uses a knife with a sharp edge to press against the material to be cut. The pressure is concentrated at the cutting edge, the pressure is very large, exceeding the shear strength of the material being cut, and the molecular bonds of the material are pulled apart and cut.

Ultrasonic cutting is a device that uses wave energy for cutting processing. The biggest feature is that it does not use traditional cutting edges.

Since the material is pulled apart by strong pressure and rigidity, the cutting edge of the cutting tool should be very sharp, and the material itself has to withstand relatively large pressure. The cutting effect is not good for soft and elastic materials, and it is more difficult for sticky materials. By preventing the occurrence of passivation of abrasive grains and clogging of pores, the processing quality of the processed objects can be improved and the service life of the grinding wheel blades can be prolonged.

The ultrasonic cutting equipment adopts a machine-mounted ultrasonic cutting knife: the maximum output power is 300w, which is used for cutting difficult-to-cut materials. A 1mm thick wear-resistant cemented carbide blade can be used, and the user can replace the blade by himself to increase the life of the cutting knife. Use less cost. Ultrasonic cutting uses ultrasonic energy to heat and melt a part of the material to be cut to achieve the purpose of cutting the material without a sharp edge.
