CNC Metal Sheet Guillotine Shear

Guillotine shears are the most common. The guillotine shear is structurally composed by two blades, a lower fixed blade and an upper blade, movable by hydraulic pistons fed by a hydraulic unit (hydraulic compressor). All the shears are provided with a device called blank holder, this allows the clamping of the material during the cutting phase, and by adjustable guides on which the sheet slides.

The guillotine shears can have very different characteristics, with blade length up to 6 m and cutting capacity up to 20-30 mm sheet thickness. Usually, especially in large shears, the upper blade is not perfectly straight but is slightly curved or tilted longitudinally. These measures are designed to reduce the cutting effort by exploiting the scissor effect.
