To maintain the accurate performance of your
CINCINNATI FM Hydraulic Press Brake, there are
maintenance practices that should be followed.
This section deals with the maintenance and
adjustments of the Press Brake.
LUBRICATION
Refer to Figure 9-1 for machine lube point loca-
tions. Lube points for the optional backgage are
shown in Figure 9-2.
FIGURE 9-1 – Lubrication points (Both housings)
1. Cylinder Head Clevis Pins: Lubricate grease
fittings while cycling the ram under load, such
as obtained with a bumping die. Use No. 2
Lithium base grease with “moly” additive (C.I.
grease H-2M). Lubricate once a month.
2. Ram Guides: Wipe clean and flush with
hydraulic oil once a month.
3. Auto Crown (Optional): There is a grease fit-
ting at each of the pins which extend through
the bed and auxiliary plate. These grease fit-
tings are either on the front or back end of the
pins in a hole through the pin retaining plates.
The pins should be lubricated monthly. Use a
No. 2 lithium base grease with a “moly” additive
(C.I. grease H-2M).
BACKGAGES (Optional)
Note: The references to “spray lubricant” means to
use “LPS #1” aerosol spray (C. I. #420924) or
to spray an SAE #10 oil. All grease applica-
tions use No. 1 EP grease (C. I. grease H-1EP).
CNC PLATE GAGE
FIGURE 9-2 – Backgage lube points
✦ Clean the Plate Gage and lubricate the two hori-
zontal guide rails on each backgage assembly
with a thin coating of spray lubricant, monthly.
✦ Lubricate the X-axis ballscrews inside the back-
gage assembly by applying the spray lubricant
through the slot in the side of each "X" housing,
monthly.
✦ Clean and lubricate the pair of horizontal guides
on the right end of the gage bar (viewed from
rear) with spray lubricant, monthly.
✦ Grease vertical guide bushings using the fitting
on the back of each casting, monthly.
The R-axis screws are packed with grease at the
factory. Disassembly of the backgage is required
for lubrication. If, for any reason, lubrication
becomes necessary, contact CINCINNATI
INCORPORATED Service Department.
