Maintenance and Lubrication
•
A maintenance unit consisting of filter, water separator and
oiler should be connected upstream of the power chuck. The
air enriched with oil supplies all sliding parts of the cylinder
chamber with an oil film. Check the oil level of the oil tank on a
daily basis and refill if necessary. If the oil consumption is too
low, i.e. if the oil level does not visibly drop over a period of 2
to 3 days, the oil adjustment screw must be opened slightly.
Depending on the accumulation of condensation, the
condensation drain screw must be opened occasionally.
The uniform clamping force, accuracy, and life span of a chuck
depend greatly on regular cleaning and sufficient lubrication. Rust,
scale, casting dust, and chips produce friction and reduce motion.
•
The chuck must be lubricated with SCHUNK LINOMAX special
grease at the base jaw lubrication nipples by means of a grease
gun after every 20
–
30 operating hours. The chuck should be
actuated two to three times here without a workpiece to
achieve optimum grease distribution by means of the
completely extended jaw stroke.
•
The fine serration of the base jaws and top jaws should always
be cleaned when the top jaws are adjusted, because otherwise
the true running accuracy will be reduced.
Even though there is optimum sealing provided by the hardened
guide bushing in the through-hole and by the closed base jaws,
foreign matter, such as dust, scale, casting dust, and fine chips can
penetrate into the chuck. In addition, the coolant also washes
away the lubricant of the chuck.
•
The chuck must be completely disassembled, cleaned and
relubricated from time to time. When doing this, replace the
sealing rings if necessary.
The time until complete maintenance depends on the presence
of dirt and the clamping frequency, so a generally applicable
rule cannot be provided.
Control of thightness
NOTE:
Temperature fluctuations must be avoided during the leak test.
The following components are required to check for leaks:
pressure gauge, shut-off valve and quick coupler.
The leak test should only be conducted when the chuck is in the
"CLOSED" position.
