9. Exhaust air from slide counterbalance cylinder (if
provided).
10. Clean the slide face and the top surface of the bed
(or bolster).
11. 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.
12. While an assistant maintains pressure on the
slide, place a base mounted dial indicator between
the slide face and bed (or bolster) and set it at the
“0” reference mark. Now take readings near each
of the four corners of the slide. (See Figure 2F.)
Results Obtained:
A. Slide parallelism is considered normal when indica-
tor 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.
B. If the readings exceed recommended tolerance,
refer to the chart entitled “Factors Affecting Paral-
lelism And Vertical Movement,” page F-11. Note
possible causes and the corrective action to be
taken.
To Check Slide Vertical Angularity:
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. Clean the slide face and the top surface of the bed
(or bolster).
9. Set base leg of machinists square on bed (or bol-
ster) (clamp if necessary) and position it in a front-
to-back plane as shown in Figure 3F.
