Comprehensive understanding of laser cleaning machines

The cleaning machine is mainly produced by the laser beam on the surface of the product instant high temperature corrosion
ablation product surface rust, coating, oil and other surface substances. It uses a laser beam with high energy density to irradiate
the surface of the workpiece, so that the dirt, rust or coating on the surface of the instant evaporation or stripping, so as to achieve
a clean green energy-saving and efficient industrial weapon.
The cleaning machine can be practically applied to quickly remove paint, rust, remove oxides, oil stains, product residues, and the
restoration and preservation of historical relics.

The composition of laser cleaning machine

Laser Source: This is the heart of the machine, producing the high-intensity laser beam used for cleaning. The laser source may use
various types of lasers, such as fiber lasers, pulsed lasers, or continuous-wave lasers, depending on the requirements  of the cleaning process.

Optics System: The optics system includes lenses, mirrors, and other optical components that focus and direct the laser beam onto
the target surface with precision. These components ensure that the laser energy is delivered accurately for effective cleaning.

Scanner or Galvanometer: This component controls the movement of the laser beam across the surface to be cleaned. 
It allows for precise scanning patterns, enabling uniform cleaning and coverage of the target area.

Control System: The control system consists of software and hardware that manage the operation of the laser cleaning machine.
It controls parameters such as laser power, scanning speed, and cleaning patterns, allowing for customization and optimization of the cleaning process.

Cooling System: Laser sources generate heat during operation, so a cooling system is essential to maintain optimal operating 
conditions and prevent overheating. This system may include air or liquid cooling mechanisms to dissipate heat effectively.

Safety Features: Laser cleaning machines incorporate various safety features to protect operators and ensure safe operation. 
These may include interlocks, enclosures, safety sensors, and warning systems to prevent exposure to laser radiation and 
other hazards.

Power Supply: The power supply provides electrical energy to the laser source and other components of the machine, 
ensuring proper operation.


How does laser cleaning work?

Laser cleaning works through a process called laser ablation, which involves using a high-intensity laser beam to remove contaminants
or unwanted materials from a surface. Here's how it typically works:

Target Surface Preparation: Before the cleaning process begins, the surface to be cleaned is prepared by focusing the laser beam
onto it. The laser beam interacts with the material on the surface, heating it and causing it to absorb energy.

Absorption of Laser Energy: When the laser beam strikes the surface, the energy from the laser is absorbed by the contaminants
or unwanted materials on the surface. This absorption causes the contaminants to heat up rapidly.

Vaporization and Ablation: As the temperature of the contaminants reaches a critical point, they undergo rapid vaporization or
ablation. This process occurs within a very short timeframe, typically on the order of nanoseconds to microseconds, depending on
the laser parameters and the properties of the material being cleaned.

Formation of Plasma: In some cases, particularly with certain types of contaminants or materials, the intense heat generated by
the laser can cause the formation of plasma. Plasma is a highly ionized gas that can interact with the surface and further aid in
the cleaning process by removing additional material.

Expansion and Removal of Debris: The vaporized or ablated material expands rapidly away from the surface, carrying away the
contaminants or unwanted materials.

Surface Inspection: After the cleaning process is complete, the cleaned surface may undergo inspection to ensure that all 
contaminants have been effectively removed and that the surface meets the desired cleanliness standards.

Two types of laser cleaning machine
There are two most common types of laser cleaning machines: One is a CW (Continuous Wave) fiber laser cleaning machine,
another one is a pulsed laser cleaning machine. The choice between these two types of laser cleaning machines depends on
factors such as the nature of the cleaning task, the material being cleaned, and the desired level of precision.



Fiber Laser Cleaning Machine is a new technology based on the interaction effect of laser and substance, different from the
traditional mechanical cleaning method, chemical cleaning method and ultrasonic cleaning method (wet cleaning process),
it does not need any ozone layer destruction of CFC organic solvents, no pollution, no noise, harmless to the human body
and the environment, is a real green environmental protection cleaning technology.
