WARNING
MAKE CERTAIN THAT POWER IS DISCONNECTED
FROM THE MAIN DRIVE MOTOR AND THAT THE
FLYWHEEL HAS STOPPED TURNING BEFORE
PROCEEDING.
8. Total gib clearance is set on one gib only. The gib
adjusting screws are located on the frame as
shown in Figure 1F. There is one set of adjusting
screws for each gib.
9. Insert a pry bar between the slide and frame.
Using the pry bar, carefully apply pressure at the
center of the slide in order to force the slide
against the opposite gib. Do not force the pry
bar. Apply only enough pressure to achieve zero
clearance at the opposite gib.
10. While an assistant maintains pressure on the
slide, check clearance created between the slide
and the gib. Total gib clearance should not exceed
0.003” to 0.004” (0.076 to 0.101 mm).
11. If measured gib clearance is not within the recom-
mended range, adjust gib setting per instructions.
To Adjust Gib Clearance:
(Ref. Figure 1F)
1. Perform Steps 1 through 10 under “To Check Gib
Clearance” to determine amount of adjustment
required.
2. Make certain slide is at bottom of stroke.
3. Place the POWER, OFF-ON-BAR Selector Switch
in the OFF position and lock the disconnect switch
in the OFF position. Attach a WARNING sign to the
press controls to warn other personnel that the
press is currently being serviced.
4. To adjust gib, start by loosening the gib locking
screws (A). Then loosen the lock nuts (B) on gib
adjusting screws (C.)
5. Turn gib adjusting screws (C) as necessary to
achieve proper clearance.
6. Recheck gib clearance, following the procedure
under “To Check Gib Clearance” to make certain
the new setting is satisfactory.
SLIDE ANGULARITY
AND PARALLELISM
Accuracy of the press is directly related to the vertical
angularity of the slide and its parallelism in relation to the
press bed. It is most important that the slide face be par-
allel with the top surface of the bed or bolster, because
parallelism affects die alignment and quality of the work
produced. Angularity is correct if the slide can be moved
from top to bottom of stroke without moving toward front
or rear of the press or to either side. Maximum angular-
ity of Model 101 OBI/OBS Series presses is .0004” (0.01
mm) per inch in the last third of downward stroke. Paral-
lelism is correct when indicator readings are within
.003”. (0.0762 mm), or when the slide face is parallel to
the bed within a tolerance of .001” per foot (0.0254 mm
per each 300 mm) of slide width, whichever is greater.
To Check Slide Parallelism:
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.
WARNING
MAKE CERTAIN THAT POWER IS DISCONNECTED
FROM THE MAIN DRIVE MOTOR AND THAT THE
FLYWHEEL HAS STOPPED TURNING BEFORE
PROCEEDING.
8. Adjust the slide shutheight to its upper limit. (See
“Slide Shutheight Adjustment” in the Operation
Manual (furnished) for further information.)
