A-6 DAILY INSPECTION
4.3 Greasing the Chuck Master Jaws
If the master jaws are not lubricated properly with grease, the gripping force of the chuck will be
reduced. If the spindle is rotated while the master jaws are not properly greased, the workpiece
will fly out of the chuck, causing injuries and machine damage.
Apply grease to the master jaws at least once a day, before starting the day's operation.
<Procedure>
1) Stop the spindle.
2) Turn off the power.
3) Supply grease from the grease cup around the
chuck.
For the name and volume of the cooling oil,
refer to the OILING CHARTS in the
MAINTENANCE INFORMATION published
separately.
Coolant splashed on the chuck will wash away the grease. Therefore, supply grease
as often as possible.
