High-end manufacturing cleaning fields include aerospace, rail transit, automobile manufacturing, mold industries, etc. For a long time, there have been problems in cleaning the parts, such as difficult cleaning, high precision requirements, and slow work efficiency. Therefore, The demand of the market has also given birth to higher requirements for the laser cleaning industry. Today, taking the most popular laser cleaning and ultrasonic cleaning methods on the market as examples, this article mainly introduces these two technologies and makes a simple comparison.\u00a0<\/div>

The principle of ultrasonic cleaning<\/h3>
Ultrasonic cleaning is to use the cross-frequency signal sent by the ultrasonic generator. This signal is converted into an oscillation by the transducer and propagated to the medium. At the same time, the sound waves radiate forward in the cleaning fluid. And then this promotes the flow of liquid to generate tens of thousands of tiny air bubbles (air nuclei) that cause the liquid to vibrate at high speed. When the air pressure reaches a certain value, the bubbles are generated rapidly and then closed. Then when the bubble closes, it generates thousands of atmospheres of pressure around it and can reach temperatures of hundreds of degrees. Therefore, the ultrasonic wave destroys insoluble dirt to disperse the dirt in the cleaning workpiece.\u00a0\u00a0<\/div>

The principle of laser cleaning<\/h3>
Laser cleaning<\/a> technology refers to the use of high-energy laser beams to irradiate the surface of the workpiece. Therefore, the dirt, rust, or coating on the surface of the material evaporates or peels off instantly. This method effectively removes the surface attachments of the cleaning object at high speed. It is a new technology based on the interaction effect between laser and matter.\u00a0<\/div>

The difference between laser cleaning and ultrasonic cleaning<\/h3>
The difference between laser cleaning<\/a> and ultrasonic cleaning is that laser cleaning is very convenient to operate. It does not need any medium and can directly clean the surface of the object. So it works well for both large area cleaning and precision parts cleaning. Usually, its working temperature is -5\u2103~50\u2103. Ultrasonic cleaning requires the addition of cleaning agents. The workpieces that can be cleaned are small, and they cannot remove coatings and submicron particles. The higher the power density of ultrasonic waves, the better the cleaning effect. However, for delicate objects, long-term high-power cleaning will cause corrosion on the surface of the object.<\/div>

Conclusion<\/h3>

In conclusion, compared with ultrasonic cleaning, laser cleaning has obvious advantages. Firstly, it is efficient, fast, and low-cost. Secondly, the thermal load and mechanical load on the material are small, so the cleaning is non-destructive. Last but not least, its cleaning process is easy to realize automatic control. So it can realize long-distance remote cleaning. JNCSLASER specializes in the laser cleaning business. We are the leading enterprise in the field of laser cleaning<\/a> in China.
