Importance of Lubrication
Running conditions of this machine depend heavily on the lubrication management.
Ensure to check the lubrication system frequently to keep this machine in a good
service condition. The followings describe how to lubricate various machine parts
properly. Recommended lubrication oil used in the pneumatic system, lubrication
grease and cutting coolant are listed in the oil guide table.
6.1.1 Lubrication and Cooling of Spindle System
6.1.1.1 Grease is used to lubricate spindle bearings. The recommended grease
(Kluber Isoflex Nbu 15) could be used in high working temperature
conditions. It has a good abrasive property, and needs no change.
6.1.1.2 Oil is used to lubricate the gearbox.
6.1.1.3 Ensure to maintain an adequate lubrication/cooling oil tank level. Fill it up if
necessary.
6.1.1.4 Oil from the lubrication/cooling oil tank is used to cool the spindle bearing
to prevent the spindle system from thermal deformation.
6.1.1.5 A fan-type cooler is used to cool the cooling or lubrication oil of the spindle
system. This fan-type cooler is standard equipment.
6.1.1.6 Instead of using the fan-type cooler, a refrigerator-type cooler will be used
to cool the cooling or lubrication oil of the spindle system upon request.
This refrigerator-type cooler is optional equipment.
6.1.2 Grease Lubrication for the X-axis, Y-axis and Z-axis Ballscrews
The working table, saddle, and headstock are traveled along the X, Y, and Z
directions respectively. Either the X-axis, Y-axis or Z-axis movement is driven by
an AC servomotor via the connection of a coupling and a ballscrew. All the
ballscrews are pre-tensioned and lubricated with proper grease to avoid positioning
error resulting from thermal deformation.
6.1.2.1 Grease is used to lubricate bearings of X-axis, Y-axis or Z-axis. The
recommended grease (Kluber Isoflex Nbu 15) could be used in high
working temperature conditions. It has a good abrasive property, and
needs no change.
6.1.2.2 Ensure to check the grease lubrication system monthly at least, and fill up
the tank if necessary. Recommended lubrication grease is listed in the oil
guide table.
6.1.2.3 Instead of the grease lubrication system, a centralized lubrication system
could be used. This centralized lubrication system is optional equipment.
NOTICE : MOVE ALL THE AXES MANUALLY BEFORE RUNNING THE
MACHINE TO MAKE SURE ALL THE SLIDEWAYS ARE
LUBRICATED PROPERLY.
