“What effects are occurring during the shearing process?” “The most common effects are: the torsion effect, and the straightness defect.” A high quality machine shall be equipped in such a way to reduce as much as possible the effects arising during the shearing process. Such effects occurring during the shearing process – if not adequately compensated – will negatively affect the final quality of the sheared material. Straightness error This error results in a work piece bowed along its plane (the surface remains flat) at the end of the cut action. It is related to the strip width,...

BLADE PADS, a precision system For an accurate and straight cut Feature Different from traditional shears which are typically equipped with two lateral blade guides, X-Cut shears are fitted with a series of adjustable pads that force accurate blade straightness every 200 mm throughout the entire length. The Blade Pads system guarantees cutting linearity and accuracy under all conditions, to achieve the best cutting quality worldwide. A precise and smooth movement contributes to the cutting linearity and accuracy. – The absence of the lateral blade sliding guides, avoids stresses, wear and...

“Can we control the material torsion effect?” “Yes, stabilizing the work-piece to the backside.” During the cutting process the material tends to twist; therefore it is recommended to support the plate against the top blade. This contrasting action avoids the torsion effects depending on the material geometry and features as well as the cutting parameters. ANTI TORSION DEVICE No sheet metal twist with the Anti Torsion Device Features The exclusive Anti Torsion Device consists of a series of hydraulic cylinders fitted below the lower blade which support the plate against the top blade. This...

“How do we achieve such a precision?” “Thanks to the back gauge which is anchored to the shear structure. It is not subject to the vibrations caused by the blade ram movement.” Gasparini | BACK GAUGE Since the back gauge is anchored to the shear structure, it is not affected by the vibrations caused by the blade ram movement. Thanks to this solution, the back gauge moves very rapidly (500mm/s) and accurately (± 0,05 mm). Furthermore it guarantees a high repeatability (±0,03 mm). Maintenance operations are reduced to a minimum, thanks to the elimination of the continuous adjustments caused...

Gasparini Industries’ shears are equipped as a standard with the best CNC available on the market. The CNC is equipped with a wide selection of functions allowing total control of the shearing process, with the possibility to adjust all the cutting parameters. – Material database stored in the CNC with sheet plate thicknesses, mechanical features and relevant cutting parameters – Cutting angle adjustment – Blade gap adjustment – Possibility to select the work piece length and the ability to control the cutting length, thus reducing the cycle time. – Program memory up to 100 cutting programs
