When use a fiber laser cutting machine for first time,customers will face many problems about machine.
So we made a simple summary of laser cutting machine use manual book.
一.Installation or Replacement Method of Interior Lens of laser Cutting Machine Laser Head
1) Before installation of optical lenses, the following items shall be noticed:
Wear clean clothes, use soap or cleanser essence to clean hands and wear light, thin, clean and white gloves;
It is strictly prohibited to touch the lenses with any part of the hand.
Hold the lenses from the side and don’t touch the coating surfaces of lenses directly when taking them.
2) Don’t blow toward the lenses when assembling them.
Please place the lenses on a clean table steadily
with several pieces of lenses professional paper lying under them.
Try to be careful when taking lenses to avoid a bruise and a fall,
and never exert any force on their coating surfaces.
The bases where the lenses are installed shall be clean
the dust dirt inside the bases shall clear with clean air gun before the lenses are placed into the bases gently.
When installing lenses into bases, never fix the lenses with too strong force
in order to avoid lens deformation and the further influence in the quality of light beam.
3) Precautions at the time of replacing optical lenses:
Be careful when taking out lenses from the packing box to prevent damaging lenses by collision
Don’t exert any force to the lenses before the wrapping paper is unpacked;
When taking out the reflector and focus lens from the packing box,
wear clean gloves and take them out from the side of the lenses;
When removing the wrapping paper from the lens, avoid dust, etc. falling down to the lenses;
After taking out the lenses, remove dust on the lenses with spray gun,
and place the lenses on the paper special for optical lenses;
Remove dust and dirt on the lens support frame and fixed mount,
and avoid other foreign matters falling down to the lenses at the time of assembly;
When installing the lenses to the base, avoid overexertion to prevent lenses deformation;
After completion of lens assembly, remove dust and foreign matters on the lenses with clean air gun.
二.Steps for cleaning the lens
Lens cleaning steps:
Blow off the dust on the surface of lens with air gun firstly;
Then remove the dirt with a clean cotton swab;
Use a new cotton swab stained with high pure alcohol or acetone to make movement
along the circumference from the center of the lens
to wash the lens and replace to use another clean cotton swab
when the circumference washing is finished every time.
Repeat the above operation until the lens is clean.
Clean cloth shall be used for cleaning lens with residual marks removed
and no scratch on the mirror surface;
Cleaned lens shall be taken to the place with sufficient ray of light for observation.
In case of good reflection situation of lens, it means the lens have been cleaned up;
in case of bad reflection situation of lens, it means that lens shall be continuously cleaned;
Install the cleaned lens into the base according to the above method.
Second-hand cotton swabs are prohibited to be used for the operation.
We will equip one pack of cotton swabs special for cleaning lens together with the equipment.
三.Storage of optical lens
1) The proper storage of optical lens could maintain the good quality of the lens.
2) The temperature of storage environment is 10-30℃,
and the lens may not be placed in the freezing chamber or similar environment,
or else condensation and frost would be caused when it is taken out, which would damage the lens easily.
The temperature of storage environment may not exceed 30℃,
or else the coating film on the lens surface may be impacted.
3) The lens shall be stored in a box in a non-vibrating environment,
or else the lens could be easily deformed, thus influencing its use performance.
