Shear Blade Adjustments; Adjustment Results - Baileigh Industrial SBR-5220 Operator's Manual

SHEAR BLADE ADJUSTMENTS

To obtain optimum results, shear alignment and shear
bow are two conditions which may need to be adjusted
depending on the gauge and type of material you want
to shear. Shears that are out of adjustment may lead to
uneven or ragged cuts.
1. Lower the shear and hold it in position.
2. Measure along the length of the blades; check the
gap of the moving blade and the fixed blade with a
0.002" (.05mm) feeler gauge as shown in figure 7.
 If the gap is the same along the length of the
blades then no further adjustment is needed.
 If the gap is unequal, proceed to Step 3.
 If you detect a bow in the gap, read the next
sub- section on shear bow.
3. Loosen the two cap screws (#13) that hold the table in place (fig. 7).
4. Turn the two adjustment screws (#52) (one on each end of the work apron) until the gap is
equal across the length of the blades.
5. Tighten the two table adjustment screws and re-check.

Adjustment Results

 Shear cuts properly along the full length. Reinstall the hold down and
follow the adjustment procedure.
 Shear cuts clean at one end but not the other. Repeat steps 2 & 3 above.
 Shear cuts at both ends of the blade but not at the center. Turn the bow
nut (A) clockwise (cw) until the paper cuts clean at all locations.
 Shear cuts at the center but not the blade ends. Turn the bow nut
counterclockwise (ccw) until the paper cuts clean the full length.
Once the blade makes a clean cut the whole length, reinstall the hold down
and follow the adjustment procedure.
