SHEARING BLADE GAP ADJUSTMENT
The shearing blade gap adjustment determines the accuracy of the cut.
Follow the procedures below to make sure this adjustment is correct for the
workpiece material being processed.
PERFORMING THE SHEAR TEST
1. While keeping your fingers clear of
the shear blades, shear a piece of
scrap material that is the same as
your workpiece along the full
length of the blade, as shown in
Figure 44, then inspect the cut.
• If the machine correctly cuts to
your satisfaction along the
entire length of the blades, no
adjustments are necessary.
• If the cut is clean at one end and not the other, perform the
following
ADJUSTING THE SHEAR TABLE
procedure that follows.
• If the condition of the cut on the ends is different from the cut in the
middle, perform the following “Adjusting the Blade Bow” on
page 27.
