OPERATING AND MAINTENANCE MANUAL FU 321M 21
LUBRICATION
The lubrication circuit diagram is shown on Fig.8 and Fig.8a indicate the recom-
mended lubricants for the various units.
The spindle gear box is lubricated by a reversible pump. The proper lubrication
of the pump is checked through the oil level indicator 4. The oil is poured in the
spindle gear box through plug 3 and is drained through pipe 1.
The feed gear box and the knee mechanisms are lubricated by a gear pump with
motor 17. The oil in the knee is poured after removing cover 10 and is drained
by loosening plug 14.
The lubrication of the guide ways for movement along the axes and the mecha-
nisms placed in the saddle is performed by the centralized System for lubrication.The
set lubrication time is for universal operation and is set by the manufacturer before
the delivery of the machine. For special operations the time for lubrication is
necessary to be changed (see "Operating and Maintenance Manual of System for
lubrification").
Pour the oil after removal of the cup 8 and the level of the poured oil can be
inspected on the transparent tank 9.
The oil for the vertical screw is supplied after removing cap 11. For this purpose
the knee should be lifted to upper end position. The oil should be to the middle
of the oil level indicator 16. It is drained through plug 15 as the knee should be
in lower end position. The tank cleaning and the complete oil change is performed
during machine repair.
When the vertical screw is in operation, it is necessary to move the knee once
or twice per workshift in both end positions.
The bearing in the yoke brackets is lubricated by a wick - feed lubricator. The
oil is poured through plug 5. The oil level should not be more than the middle
of the oil level indicator 6.
During operation follow the instructions on the machine panels.
