(2) Laser current can't be too much and must be lower than 20mA. In addition, light
intensity should be adjusted to be small as far as possible under the condition of
satisfyi
ng
engraving depth and speed. 13～l 7mA is relatively suitable current range.
(3) Laser阳be is heating element, so the quality and quantity of circulating water
should be assured. Quality-be sure there is no dirt. R e plac e circulating water
regularly ( every two days). Replacing water is carried out when machine shuts down.
Quantity-be s
田
c there is enough circulating water (more than 20kg). Be s
旺
c the
temperature of circulating water is between 5～25℃
( 4) Under the condition of satisfying working requirement, optimum working method
should be used to extend service life of laser tube as far as possible.
2. reflector lens and focusi n g lens
The surfaces of reflector lens and focusing lens has been polished precisely and plated
a layer of thin film . Their surface cleanliness affects directly the reflector rate and
focusing effect of laser , so they should be cleaned and maintained regularly. Clean
should be followed strictly maintenance procedures, which can extend their service
life.
3. water pump and air blower
Their maintenance is relatively simple. When machine stops working, they should be
turned off in time. Dust must be removed and cleaned regularly so as not to influence
the working effect and service lift. Air blower has special protect measures. It can
’ t
work in the rain and in intense sunshine.
