WORKING
WITH
THE
MACHINE
When
angle
rails
are
used for
bending, the
setting
dimension
for
the lower
and
bending
cheeks
is
e
=
1.25
x sheet
thickness
The value
must
be
set
and
checked
on the
respective
scales.
H(AMPLE:
When bending
a
metal
sheet 0.12
inches
thick
with
the minimum
possible bending
radius
(refer
to ltem 1
"TEdHNICAL
DATA"),
the setting
for the
lower cheek
and
bending
cheek
is as follows:
e
=
1.25 x
0.12 inches
=
0.15 inches
The lower
cheek
and
the bending
cheek
must therefore
be set
to 0.15
inches
When radius
rails
are
used for
bending,
the
setting
for
the lower
cheek
and
bending
cheek
is as
follows:
e
=
radius
+ sheet thickness.
The value must
be set
and
checked
at
the relevant
scales'
EXAMPLE:
When
bending
a
metal
sheet
0.08
inches
thick
with
a radius
rail R
=
0.59
inches,
lhe
setting
for
the lower
cheek
and
bending
cheek is
as follows:
e
=
(0.59 + 0.08)
inches
=
0.67
inches
The
lower
cheek
and
lhe
bending
cheek
must
therefore
be
set
to 0.67
inches
