Laser cutting machine lens has oil how to solve? Laser cutting machine lenses play a crucial role, mainly involving the focus and protection of two major functions. The focusing lens is responsible for accurately focusing the laser output beam to form a very high energy density spot, ensuring accurate and efficient cutting. This process is based on Gaussian optics to maximize the power density at the focal point, allowing for fast and precise cutting of the material.

1. Check and optimize the air source: First check whether the air source provided for the air compressor is clean to ensure that no oil enters the air stream. It may be necessary to install or inspect existing oil and water separators and air drying equipment (such as cold dryers and suction dryers) to ensure that they are working properly and can effectively remove moisture and oil mist from the air.

2. The use of rotary oil-water separator: consider installing such professional equipment as Zhejiang Leili rotary oil-water separator, which can efficiently separate the oil and water mist in the air stream and reduce lens pollution.

3. Regular maintenance and inspection: regularly check the cooling system for leaks, to ensure that the equipment such as cold and dry machines are maintained in accordance with the manufacturer's recommendations, to prevent water and oil mixing problems caused by equipment failure.

4. Lens cleaning:

Initial blow off: Use an oil-free and water-free air ball to gently blow away dust and particles on the surface of the lens.

Chemical cleaning: If there is oil on the lens, it can be gently wiped with analytical pure acetone. The operation should be gentle and quick to avoid damage caused by wiping back and forth. If acetone does not work, try cleaning with diluted sour vinegar (laboratory grade or household white vinegar), then cleaning again with acetone to remove the vinegar residue and dry the lens. Remember to use a new cotton swab or lens paper each time and follow the correct cleaning sequence and technique.

Protection: During the entire cleaning process, be sure to wear clean gloves to avoid direct hand contact with the lens to reduce the risk of contamination.

5. Environmental control: Ensure that the working environment of the laser cutting machine is dry and clean, and reduce the pollution of the lens by external factors.

Through the above measures, the oil pollution problem on the laser cutting machine lens can be effectively solved, and the cleanliness of the lens can be maintained, so as to ensure the cutting quality and the stable operation of the equipment.
