4.1 DAILY INSPECTION
Table 4.1 lists daily inspection items. Inspect the FANUC LASER
C1000/C2000/C4000/C5000/C6000-MODEL E according to this table.
When parts (including oil) have been used for a prescribed period,
replace them quickly.
Table 4.1 Daily inspection items for FANUC LASER C1000/C2000/C4000/C5000/C6000-MODEL E
Item Period Content and instruction
1 Residual laser gas Daily
Check to see if the primary pressure is 1.0 MPa or less as measured at the
regulator on the laser gas cylinder. If the primary pressure is 1.0 MPa or lower,
replace the gas cylinder. See Section 4.4.2 for the gas specifications.
2 Exhaust pump oil Weekly
Make sure that the oil level is between L (minimum) and H (maximum). Usually,
oil is supplied until the oil level is in the middle between L and H. If the oil level is
below L, supply oil according to Section 4.3.2. Be sure to replace the oil
periodically, every 6 months of use or every 1500 hours of operation, whichever
is earlier.
3 Exhaust pump oil leak Weekly
Make sure that no oil is leaking from the vane pump main body, drain cock and
their periphery. If oil is leaking, immediately replace the exhaust filter according
to Section 4.3.3, because it is likely to have been clogged. Be sure to replace the
exhaust filter periodically, every one year of use or every 3000 hours of
operation, whichever is earlier.
4 Turbo blower oil Weekly
Make sure that the oil level is between L (minimum) and H (maximum) according
to Fig. 4.3.1. Usually , oil is suppled until the oil level is at 3/4 above L. If the oil
level is below L, supply oil according to Section 4.3.1. Be sure to replace the oil
periodically, every 4 months of use or 1000 hours of operation, whichever is
earlier.
5 Turbo blower oil leak Weekly
Make sure that no oil is leaking from the turbo blower main body, oil inlet, cock,
and their periphery. If oil is leaking, locate the leak. If oil leaks for any reason
other than a cock being open, call FANUC.
6 Laser output Weekly
1. Check to see if the laser output measured at the outlet of the short optical path
oscillator is 5% or more lower than the specified output. If this is the case,
clean or replace the optical components in the external reflection unit.
2. If the laser output decreases within the oscillator, warning message No. 4085
is issued. If this message appears, clean or replace the mirror in the oscillator
quickly.
Daily Make sure that the chiller discharge output is 0.5 MPa or less.
7 Cooling water
Weekly
Check the quality of cooling water circulating in the chiller. If the water is colored
badly, replace it completely. Be sure to replace the cooling water every two
months. Adding an anticorrosive to cooling water can decrease the replacement
frequency. See Section 3.4.2 for descriptions about the anticorrosive.
