Built-in Rigidity

squaring shears | high-speed shears

All FAMCO shears have the built-in rigidity to shear very narrow strips of full capacity material, without offsetting. Under this test, a weak bed and crosshead construction would cause deflection--the narrow strip would bend over, rather than shear with a clean edge as it does with the FAMCO shear. Shears of cast construction mistakenly cite weight as an indicator of rigidity, instead of the strong internal design and construction that assures true rigidity.

On most models, FAMCO has a low crosshead blade rake. This is especially important when shearing narrow strips of full width material. High blade rake would cause bow, twist, and camber in the back piece. FAMCO's lower rake angle substantially reduces this condition. You shear with confidence using your FAMCO shear.

Non-metallic crosshead gib bearings on all FAMCO shears are Texolite, and are located on the front, back and ends of the crosshead. Non-metallic gibs permit setting a close clearance in the gib ways by means of the tapered gib spacer. This is particularly important on light-gauge material where blade clearances are at a minimum and a burr-free cut is mandatory. If gib way clearances were excessive, the crosshead could move in the ways when the material is contacted, thereby increasing the blade clearance and causing a poor sheared edge. the FAMCO crosshead remains truly aligned on even the most difficult cuts.

FAMCO uses the adjustment block design on all models and sizes similar to that used on heavy gauge and plate shears, to assure utmost dependability and rigidity. The individual blade seat adjustment blocks, are spaced six to eight inches apart and permit extremely accurate blade clearance settings throughout the full length of the shear, without shimming or other compromising procedures. These adjustment blocks can be quickly set to an exact blade clearance for more accurate and burr-free shearing.
