Blade Clearance Adjustment - Baileigh Industrial SH-120250-HD Operator's Manual

Blade Clearance Adjustment

To obtain a high-quality shearing section, a suitable blade clearance must be selected according
to the material to be cut. This shear is equipped with a fast adjustment handwheel for blade
clearance.
Note: This is a general guide for setting the blade gap. Your specific settings may
change based upon several factors regarding specific material and other machine settings and
conditions. This is based upon a general guideline of blade gap is equal to 6.5%-7% of material
thickness. These settings are based upon mild steel. Other material will differ. Generally, slightly
larger gap for material such as stainless steel, and a slightly smaller gap for softer material of
aluminum or copper.
Under no circumstances do you want the blades making contact with each other as this
can cause blade breakage as well as premature dulling of the cutting edges.
1. With the blade in the fully up position, rotate the
handwheel until the pointer is pointing at the closest
dimension for the material to be cut.
2. Operate the shear for 1 or 2 cycles with NO
material to verify that there is no interference and
allow the shear ram to fully position.
3. Test the cut on scrap material. Fine adjust if
needed. Keep notes about the gap position for
each specific material and thickness.
Note: Whenever the adjustment has
been completed, trial shear scrap or excess material of
the same exact type as the production piece to verify
the adjustments. Readjust as needed until a
satisfactory shear section is obtained.
Note: For shearing plastic material, the
blade clearance should be a little bit smaller and a little bit larger for brittle material.
