The inspection and servicing procedures described in
this section should only be performed by authorized
personnel who are experienced in the maintenance of
mechanical power presses. Normally, the adjustments
outlined need be performed only if related parts of the
press have been disassembled or an inspection
reveals the need for readjustment.
Servicing procedures in this section explain checking
gib clearances; setting gibs for proper running clear-
ance; checking slide angularity and parallelism; adjust-
ments for correcting slide angularity and parallelism.
Procedures for connection cap installation, and cali-
brating the shutheight indicator are also included in this
section.
The slide assembly on Model 101 OBI/OBS Series
presses are precisely guided with hydrodynamically
lubricated V-type gibs at the rear corners. The gibbing
consists of angled bearing surfaces that guide the slide
in both the front-to-back and right-to-left directions. The
gibs are accurately squared with the bed, set for prop-
er running clearance, and clamped with heavy gib bolts
to the frame. Both gibs are adjustable
GIB ADJUSTMENT
(Ref. Figure 1F)
Adjustable gibs are bolted to the press frame to provide
guiding surfaces at the side of the slide. Correct gib
adjustment holds the slide on the front-to-back center
line of the press. Adjustable gibs are bolted to the frame
and contact the side surfaces of the slide.
Properly adjusted gibs are an important factor in main-
taining parallelism between the slide face and top of
press bed or bolster. Loose gibs will cause unsatisfac-
tory stamping or forming; tight gibs will squeeze out the
oil film and damage the gib sliding surfaces.
Follow the suggested gib inspection and adjustment
procedures outlined in this manual. If the inspection
shows that adjustment is necessary, correct the clear-
ances by adjusting the gib adjusting screws.
To Check Gib Clearance:
(Ref. Figure 1F)
1. If press is inclined, return the press to the full verti-
cal position.
2. Remove dies or tooling from the press.
3. Turn ON the air supply to the press. Charge the
counterbalance cylinder (if applicable) with air pres-
sure that is at least equal to the amount shown for
“0” die weight.
4. Place the POWER, OFF-ON-BAR Selector Switch
in the ON position.
5. Start the main drive motor. Make certain that oil is
dripping from the gibs.
6. Place the Stroking Selector Switch in the INCH
position. Then position the slide at the bottom of the
stroke.
WARNING
MAKE CERTAIN THAT ALL PERSONS ARE
CLEAR OF ANY PINCH POINTS ASSOCIATED
WITH THE OPERATION OF THE PRESS AND/OR
ITS AUXILIARY EQUIPMENT.
7. Stop the main drive motor. Place the Stroking
Selector Switch in the OFF position. Make certain
that the flywheel has stopped turning completely.
Attach a WARNING sign to the press controls to
warn other personnel that the press is currently
being serviced.
