The CO2 laser focus lens is a relatively precise optical element, and its cleanliness directly affects the processing performance and quality of laser cutting machine. Therefore, it is very necessary to maintain the focus lens regularly.
Here are the correct operations of lens maintenance:
1. Take out the lens from the laser head set: loosen the fastening screws, take off the air nozzle and the lens barrel in turn, and blow off the dust on the lens surface with a blowing balloon.
2. If you really need to clean the lens, you can only use the special lens cleaning paper dip in appropriate amount of anhydrous alcohol, and gently rotate clockwise from the center of the lens to the edge. When necessary, both sides of the lens need to be cleaned, and care should be taken when scrubbing.
3. Install the lens barrel and air nozzle, adjust the focal length, and tighten the screws. When installing the focus lens, be sure to keep the convex surface upward.
The focus lens belongs to consumables, and it needs to be replaced when it still can't achieve high cleanliness after cleaning for many times, so as to ensure the processing efficiency of the laser cutting machine and avoid production delay.
