21. Turn CONTROL ON-OFF keyswitch to “OFF” and
remove key.
22. Fully tighten the die clamp nuts after seating the
upper die. Check the shoulders of the die with a
.002” (.05mm) feeler gage to make sure it is seated
tightly. Turn CONTROL ON-OFF keyswitch to
“ON”.
23. Run the ram upwards to provide clearance between
dies. This clearance should be equal to at least the
metal thickness. Turn CONTROL ON-OFF
keyswitch to “OFF” and remove key. Check the
front-to-back die alignment over the full length of
the dies. Realign if necessary by moving the filler
block with die aligners. For precision bending
requirements, a more accurate alignment is required.
Feeler gages should be used to measure front-to-
back die clearances between the upper and lower
dies at both ends and at the center of the dies.
24. Tighten the filler block to the bed.
GAGING – OPTIONAL BACKGAGE
There are four types of optional backgages available on
the 90-350 PROFORM. The CNC Backgage and the
CNC Heavy Duty Backgages have a 24" or 40"
powered X-Axis (front-to-back) and an 8” manual R-
Axis (vertical) adjustment. These backgages have an
optional programmable powered R-axis available. The
CNC Plate Backgage has a 24", 40", 64" or 80" X-Axis
and a 8" or 12" powered R-Axis. The CNC 4X Backgage
has a 24" or 40" powered X-Axis and 8" or 12" powered
R-Axis. It also has a powered Z-Axis (right to left).
CAPACITY
The CNC Backgage is designed for sheets, 3/16”
(4.8mm) maximum thickness, that weigh less than 100
lbs. (45 kg). The CNC Heavy Duty Backgage and CNC
4X Backgage are designed for sheets 1/4” (6.4mm)
maximum thickness that weigh less than 150 lbs. (68
Kg). The CNC Plate Backgage is used for gaging large
plates or sheets weighing over 500 lbs. (227Kg).
Reasonable care should be used when positioning heavy
sheets against these gages.
IMPORTANT: Heavy shock loads could damage parts
of the gage.
The standard horizontal (front-to-back) travel is 24”
(610mm). It is power driven at 1200 in/min. for the
CNC, Heavy Duty, and 4X Backgages and 400 in/min.
for the CNC Plate Backgage. The gage is positioned and
sequenced by the program entry in the PROFORM
control. The gage fingers are manually positioned along
the length of the gage bar using a gage positioning tool
or programmed on the 4X backgage.
GAGE ASSEMBLY
Two gage assemblies are furnished with each backgage
and are mounted on the backgage gage bar. The gage
assemblies (Figure 5-8) are manually positioned along
the length of the gage bar, usually centered on the
tooling and spaced apart a distance less than the length
of the workpiece.

Two pairs of gage fingers are furnished with each
backgage. The 1” (25mm) gage finger or the 1/4”
(6.4mm) gage finger is installed into the gage assembly
