The lens of a laser cutting machine can be reused, but without proper protection and maintenance, it can easily burn, crack, or become damaged. Here are some tips to prevent lens damage and ensure reuse:
Common Issues and Causes
- Quality Problems: Lenses from some manufacturers may burn due to poor quality or lack of maintenance. Inferior lenses are more brittle and prone to damage.
- Handling Errors: Accidental touches or collisions during disassembly and assembly can affect the lenses.
Maintenance Tips
- Daily Dust Removal: After finishing work each day, meticulously remove dust. Be careful when cleaning, as lenses are sensitive to falling and touching. Always remove dust before replacing new lenses.
- Blowing Delay and Focal Length Adjustment: Increase the blowing delay and adjust the focal length according to the thickness of the plate and air pressure stability.
- Perforation Management: Monitor the number of perforations. Higher output frequency increases the risk of lens damage from perforation sputtering. Set the time before perforation, generally not exceeding 150 continuous waves at 500Hz.
- Daily Inspection: Check for oil or water on the lens daily. The cutting machine produces gas during operation, which can blow away residue and prevent it from entering the lens, protecting it effectively.
Additional Tips
- Air Compressor Dryer: Ensure the air compressor dryer operates normally every day.
- Regular Maintenance: Consistent cleaning and maintenance are essential to extend the lens’s lifespan and avoid frequent burnouts.
By these maintenance tips, you can ensure your laser cutting machine lens remains in good condition and is reused for a long time.
