Pulse laser cleaning machine is a kind of equipment that uses a pulsed laser head to irradiate a high-energy beam to the surface of the workpiece, so that the dirt, rust, coating, etc. on the surface evaporate or peel off instantly, thereby achieving efficient cleaning. The following is a detailed introduction to the pulse laser cleaning machine:

### 1. Working principle

The working principle of the pulse laser cleaning machine mainly includes the following steps:

1. **Laser beam irradiation**: The beam emitted by the laser is absorbed by the contaminated layer on the surface to be treated.

2. **Energy transfer and expansion**: After the laser energy is absorbed by the contaminated layer, it expands due to heat. When the expansion force of the dirt is greater than the adsorption force of the dirt on the substrate, the dirt will detach from the surface of the object.

3. **Light pulse control**: The light pulse width must be short enough to avoid heat accumulation that damages the treated surface.

4. **Laser beam focusing**: The laser beam has a small divergence angle and good directionality. The focusing system can make the laser beam focus into spots of different diameters to achieve precise cleaning.

### 2. Features and advantages

1. **Non-contact cleaning**: Laser cleaning does not require direct contact with the workpiece surface, avoiding mechanical damage and secondary pollution that may be caused by traditional cleaning methods.
2. **Precise and efficient**: The laser beam can accurately control the cleaning area and depth, achieving micron-level cleaning accuracy, while having high cleaning efficiency and fast speed.
3. **Environmental protection and energy saving**: Laser cleaning does not produce pollutants such as dust and wastewater, which is environmentally friendly; at the same time, the laser energy utilization rate is high and the energy consumption is relatively low.
4. **Wide range of application**: Pulse laser cleaning machine can be used for surface cleaning of workpieces of various materials and shapes, including metals, non-metals, precision instruments, etc.

### 3. Application fields

Pulse laser cleaning machines are widely used in many fields, mainly including:

1. **Manufacturing**: In the manufacturing industry, many parts and products need to be surface cleaned to ensure quality and performance. Pulse laser cleaning machines can quickly and effectively remove dirt such as oil and oxides on the surface of parts, improving product quality and production efficiency.
2. **Aerospace**: In the field of aerospace, the cleanliness of the material surface is extremely high. Pulse laser cleaning machines can remove all kinds of dirt and coatings without damaging the surface of the material, meeting the high requirements for surface cleaning in the field of aerospace.
3. **Cultural Relics Protection**: In the field of cultural relics protection, traditional cleaning methods often cause damage to cultural relics. Pulse laser cleaning machines can remove surface stains and dust without damaging cultural relics, restoring the original appearance of cultural relics.
4. **Other fields**: Pulse laser cleaning machines are also widely used in automobiles, electronics, construction and other fields, providing efficient and environmentally friendly solutions for surface cleaning in various industries.
