What To Do If The Laser Cutting Machine Lens Cannot Operate Normally When It Encounters Oil And Water？

1. Cause of the problem

During the laser cutting process, the laser beam needs to pass through multiple lenses for focusing before it can achieve the purpose of cutting. The contamination of the lens surface by oil and water will change the refractive index of the laser beam, resulting in a decrease in cutting quality or failure to operate normally.

2. Solution

For this problem, we can start from the following aspects:

●Keep the work site dry

The laser cutting machine should keep the work area dry during operation to prevent impurities such as water droplets and oil from falling on the lens surface, affecting the cutting accuracy and quality.

●Clean the lens regularly

The lens is the core component of the laser cutting machine to ensure the cutting quality, so it is necessary to clean the lens regularly. Generally speaking, the lens of the cutting machine should be cleaned once a week. By wiping the lens surface with pure alcohol, the oil on the lens can be effectively removed to ensure that the laser beam can fully pass through the lens.

3. Replace the lens

If the cutting quality and efficiency are reduced and cannot meet the operating requirements, it means that the lens has expired or has been severely damaged. At this time, a new lens should be replaced in time.

4. Add protective measures

For some laser cutting machines that require liquid cooling, protective measures can be added to prevent oil and water from contaminating the lens. For example, add shielding plates around the cutting area to reduce external pollution invasion, or use oil-proof and waterproof lenses.

In short, for the problem that the laser cutting machine lens cannot operate normally due to oil and water, we need to take effective countermeasures in time to ensure the stable operation of cutting accuracy and efficiency.
