Flip Fingers
Flip fingers permit closer gauge positioning to the tooling. The fingers’
tilting action allows reverse bending, with the length of the reverse bend
dependent on the type of part to be formed.
Fingers can be manufactured by customers to suit their individual forming
needs. For the most accurate results, always reference the flip fingers prior
to using them after changing the tooling setup. Refer to the “Referencing
the Gauging Surface” section that follows.
Install the flip fingers at any location along the gauge bar to best suit the
requirements of the part. These fingers allow approximately 0.090" of
horizontal micro-adjustment for close-tolerance forming. Fingers rotate in
90° increments for narrow or wide target area selection. Each finger tilts
on a leveling adjustment screw at the front bottom of the body. The
locking screw at the end of the flip finger assembly is used to lock it in
place along the gauge bar.
When two flip fingers are used, both must be set to the same length, as
measured from the back of the body to the tip of the finger. Otherwise, the
parts will not have equal flange lengths on both ends.
Gauge Blocks
Gauge blocks provide a large target area suited for work involving large-
scale parts and long flanges.
Install gauge blocks at any location along the gauge bar to best suit the
requirements of the part. The locking screw at the end of the gauge block
is used to lock the block in place on the gauge bar. For the most accurate
results, always reference the gauge blocks prior to using them after
changing the tooling setup. Refer to the “Referencing the Gauging
Surface” section that follows.
