Introduction of main vulnerable parts
1. Laser tube
This machine uses home-made sealed off type carbon dioxide laser tub e. Air volume
in pipe is fixed, whose service life is about 1 OOOh. Its service can be roughly divided
into four phases (average 8 hours every day):
Phase one: excellent phase, when laser tube is in steady sta t us. All performances are in
the best status.
This phase can last about 2
～
3 weeks.
Phase two: steady phase, when laser tube is in steady status. Under the same curre时，
light intensity is a little weaker th an也at in phase one, but is eno ugh to satisfy working
demand. This phase can last about l～2 months.
Phase threes: decline ph ase. After being used for a quite long tim矶every index of
laser 阳be begi ns to decrease. The light intensity becomes weaker. Now, you can
increase current and s low down speed to s atisfy your requirement for engraving depth.
This phase can last about half to one mon也
Phase four: depletion phase. The service time of laser阳be ends.
It can be found from 出 e process of laser service life. The length of steady phase is the
key of laser tube usage. The quality of maintenance affects directly the leng出 of
steady p hase . The essentials for maintenance are as follows:
(1) Machine working environment must be fine. Power voltage must be steady. If
voltage fluctuates too much
乡
steady power supply should be equipped. The machine
must be placed steadily wi吐1out great vibration, and can
’
t work in damp environment.
