22. Lower the finger receiver and remove the
workpiece (Figure 17 ).
Bending operations require the fingers to be in line
with the finger receiver. When moved, the fingers
are held stationary while the work lever raises the
workpiece and finger receiver into the tips of the
fingers. As a result a bend occurs. If a pan or box
bend is desired, choose a finger or a selection of
fingers that are as close as possible to the length
of the pan or box side lengths. Remove the fingers
that may interfere with the bend.
Tip: During a bending operation, the fingers push
the sheet metal down into the groove of the finger
receiver. As the sheet metal slides down into the
groove, scoring may occur. To avoid these marks,
keep the receiver free of burrs, and adhere a strip
of tape on the workpiece underside along the
location to be bent.
To cut sheet metal:
Adjust the rear stop to fine tune your cut
length (Figure 18). For the most accurate
cuts, make sure that you have at least one
square edge of the workpiece up against the
stop or a guide.
24. Place your workpiece to the far left of the
shearing table and against the guide (Figure
19).
