Advantages of Laser Cleaning Machines over Other Cleaning Technology


There are many cleaning methods, such as mechanical cleaning, dry ice cleaning, chemical cleaning, sandblasting cleaning, ultrasonic cleaning, laser cleaning, and so on. Among them, the first four methods are traditional cleaning techniques, and most of which are cleaned by chemical methods or mechanical methods. CNC laser cleaning technology is a new green cleaning method in recent years. Specifically, the comparison between laser cleaning and other traditional cleaning methods is described below.


It uses a dry ice cleaner to spray dry ice pellets on the work surface. The energy conversion will achieve impurity removal by high pressure air. And it has the characteristics of zero cleaning damage and high cleaning efficiency, but high cost and high unsafety.


It spray copper sand, quartz sand, emery, iron sand, sea sand, or other particle onto the surface of the material. But it usually causes damage, air pollution, and noise. To make matters worse, the resulting respirable particles can cause harm to the human body.


It adopts chemical methods or chemical reagents to achieve equipment cleaning. It will corrode the processed metal materials, which is not conducive to long-term cleaning. In addition, industrial wastewater is also produced, which is harmful to human health.


Use ultrasonic cavitation to disperse, emulsify, and peel off the dirt layer to achieve cleaning.


The fiber laser cleaning machine uses the instantaneous high temperature generated by the laser beam to clean the impurities from the processed material surface. So as to realize CNC laser cleaning, energy saving, and environmental protection. It has the characteristics of free grinding, non-contact, no thermal effect, and zero damage.


Mechanical cleaning has high cleanliness, but it is easy to damage the substrate. At the same time, chemical cleaning is a non-pressure cleaning, but the pollution is heavy. While liquid or solid jet cleaning has high flexibility, it is costly and contains a lot of impurities. Although the ultrasonic cleaning method has a good cleaning effect, it is powerless to sub-micron dirt particles. In addition, the size of the cleaning tank limits the cleaning range. And drying after washing is also a big problem.


Compared with traditional cleaning technology, CNC laser cleaning still has many advantages. It makes up for the shortcomings of traditional cleaning methods and promotes the application of laser technology in the field of surface cleaning. Due to its many advantages, laser cleaning is now the most effective method for removing unwanted substances from the surface of materials. Below I will list some of the more prominent advantages of laser cleaning technology.

1. Laser rust removal is a “green” cleaning method, which does not require the use of any chemicals and cleaning fluids, no exhaust gas emissions, and no environmental pollution. The cleaning residues are recovered by vacuum cleaners. 2. CNC laser cleaning can effectively clean the submicron particles that are difficult to remove cleanly adsorbed on the surface of objects by other methods. 3. The laser can be transmitted through optical fiber, cooperate with the robot hand and robot, can realize automatic control and long-distance remote control, and can clean the parts that are not easy to reach by traditional methods, which can ensure the safety of personnel in some dangerous places. 4. Laser cleaning can selectively clean the contaminants on the surface of the material without damaging the surface of the material. High cleaning efficiency, saving time and lower cost. 5. CNC laser rust removal has good controllability and high flexibility, and is easy to achieve precise cleaning in selected areas and in real time. 6. The heat-affected zone is small. For light peeling cleaning, it is to open the bond of the material. There is no thermal effect and no thermal damage to the surrounding materials. No damage to molds – extended mold life. 7. The car tire mold can be cleaned online, with fast cleaning speed and easy operation, without any consumables (except electricity) and chemicals. 8. Although the initial one-time investment in purchasing a laser cleaning system is high, the cleaning system can be used stably for a long time, with low operating costs and almost no warranty requirements.
