Top blade and back gauge swing together allowing the material to remain perpendicular to bottom blade then swing away from the bottom blade after the cut thereby preventing jamming of the material between the blade and the back gauge.
Masteel swing beam shears do not require a relief angle therefore the force created by the hydraulic cylinder is applied directly against cutting load. Cutting loads do not deflect the cutting blades or beam mechanism and therefore blade clearance gap remains consistent through the cut. This feature allows Masteel shears to cut strips narrower than the material thickness without damage to the blades or machine structure.
Mono-block type, welded frame and blade beam construction are optimized by computer-aided engineering to guarantee maximum rigidity. Heavy-duty taper roller bearings are located at swing beam centers so that cutting load is always perpendicular to blade beam rotational radius. This avoids cutting loads being transferred to the support bearings thereby insuring longer life and consequently better accuracy over the long term.
