The phenomenon of water mist on the lenses of the laser cutting machine is mainly due to the large amount of water vapor generated during the use of the laser cutting machine, which will condense on the lenses to form water mist.
The Influence of Water Mist on Cutting Machines
The water mist on the lens can affect the transmission and focusing of the laser beam, leading to loss of laser energy, a decrease in cutting quality, and even damage to the cutting machine.
Method for removing water mist
1. Using desiccant: Place a small bag of desiccant inside the cutting machine to absorb as much moisture as possible from the air. Desiccants are generally silicone, and desiccants such as white carbon black can also be used, which has a significant effect on small area water mist evaporation.
2. Temperature regulation: When the cutting room temperature is too high, water mist can easily appear. It is recommended to reduce the room temperature appropriately and increase ventilation to remove indoor moisture.
3. Use a fan: Use the built-in fan of the machine or an additional fan added to the equipment to clean and ventilate the cutting room and sweep away water mist.
4. Cleaning lenses: Remove and clean lenses with heavy water mist, dry them, and reinstall them. Cleaning should ensure sufficient hygiene conditions and be wiped with alcohol or pure water.
5. Material replacement: Replace the lens material and choose a material with good hydrophilicity. The specific selection method can be consulted with the cutting machine manufacturer.
By using the above methods, the water mist on the laser cutting machine lens can be effectively removed, thereby improving cutting quality and efficiency. When using a laser cutting machine, attention should be paid to protecting the lenses, cleaning and replacing them in a timely manner to ensure the normal operation of the cutting machine.
