The laser cutting head lens is a core component of laser equipment, and its cleanliness directly affects cutting accuracy and equipment life. Below is a standardized maintenance guide tailored specifically for laser product shop customers. It's compatible with most mainstream cutting head models, and all necessary tools and consumables can be purchased in-store from a single source.

1.Prepare the Operating Environment:

Choose a dust-free cleaning surface (equipped with a top filter) available in-store. Power on the surface in advance and wait for the internal air circulation and filtration to complete. Ensure the operating area is free of visible dust before proceeding to the next steps to prevent secondary contamination of the lens caused by ambient dust.

2.Tools and Supplies List
Gather the following supplies in advance, all of which are popular and compatible items in our store:

1. Lens Removal Tools: Includes a graduated wrench (compatible with different cutting head screw sizes) and a lens suction cup (to avoid direct contact with the lens surface);
2. Inspection Tool: 1064nm wavelength red light pen (for checking lens cleaning effectiveness);
3. Protective Consumables: Low-tack masking tape (residue-free, prevents dust from entering the optical cavity);
4. Cleaning Consumables: Laser lens cleaner (non-corrosive, compatible with all lens materials), grease-free cotton swabs (lint-free and fiber-free).

3.Practical steps

1. To remove the lens module, align the lens retaining screws with a graduated wrench and slowly loosen them counterclockwise (applying even pressure to prevent stripping). After removing the lens module, immediately seal the optical cavity opening in the cutting head with masking tape to prevent dust from entering.
2. To disassemble and clean the lens, use a lens removal tool to loosen the lens clamp and remove the lens to be cleaned. Take a grease-free cotton swab, dip it in a small amount of specialized cleaning agent, and gently wipe along the lens surface in the same direction (avoid rubbing back and forth to prevent scratching). Focus on the edges and center of the lens where dirt easily accumulates. If stains are stubborn, replace the cotton swab and repeat the process once. After cleaning, place the lens on a dust-free tray to dry.
3. After the lens is completely dry, return it to the fixture, ensuring the lens is centered and free of offset. Then reinstall the fixture. Align the cleaned lens module with the cutting head interface and slowly push it in. Tighten the fixing screws clockwise with a graduated wrench, maintaining the same pressure as when disassembling to prevent uneven force on the lens.
4. To check the cleaning effect, remove the factory masking paper from the fiber optic connector and insert a red light pen. Remove the masking paper from the nozzle, turn on the red light pen, and observe the light output point. If the red light point is round and free of dark spots or shadows, the lens is properly cleaned. If any abnormalities are present, disassemble the lens and clean it again according to the above steps.

4.Notes:
Do not touch the lens surface directly with your fingers during the entire installation process to avoid fingerprints and oil stains.
After cleaning, install the lens within 10 minutes to minimize exposure to air.
We recommend purchasing the correct tools and consumables from the store to avoid maintenance problems due to mismatched specifications.
