Refill central lubrication system
The CNC machine is equipped with a central lubrication system.
INFORMATION
The CNC milling machine is delivered without lubricating oil. The central lubricating system is
located on the left-hand side of the machine housing.
The central lubrication system and the choke manifold system is preset and must not be
adjusted or re-adjusted during the commissioning of the machine. The discharge volume is 1.0
cm

per cycle.
Refill the reservoir with oil through the fill cap.
"Cooling lubricants“ on page 160
The central lubrication system supplies the lubricating points automatically.
The cycle time is fixed and can not be changed.
The discharge volume per cycle can be reduced, however, should remain at the factory set-
ting.
Function:
Lubricator is a motor-driven, spring discharge piston pump. The motor incorporates a gear
reduction which determines the operating cycle time of the pump piston. The SLR-chokes are
cyclically supplied with the set flow rate of oil. The delivery rate is distributed over the various
chokes to the lubrication points.
