Sheared surface quality: 
Shearing machines are meticulously designed in terms of tooling and parameter settings to ensure high-quality sheared surfaces. The tools feature optimal shapes and specific blade angles, and during operation, parameters such as tool clearance can be precisely adjusted based on factors like the material and thickness of the sheet. This allows the blade to apply shear force evenly during the cutting process, resulting in a smooth and flat sheared surface with minimal defects such as burrs or tear marks that could compromise surface quality. For instance, in sheet metal processing, if the sheared surface quality is poor with excessive burrs, these burrs may cause cracks during subsequent bending operations, adversely affecting the overall product quality. In scenarios where surface coating is required, a smooth and flat sheared surface eliminates the need for additional time and costs to treat rough surfaces, allowing the material to proceed directly to the coating process, thereby enhancing production efficiency and product quality. 

Sheet deformation control: 
High-performance shearing machines prioritize controlling the degree of sheet deformation during the cutting process. Through optimized mechanical structures, such as rational workbench support mechanisms and tool movement guidance systems, combined with scientifically designed cutting techniques, these machines effectively balance forces in all directions when applying shear force to the sheet. This reduces deformation issues like warping or twisting caused by the cutting force. Particularly when cutting thin sheets, which are more susceptible to deformation under external forces, this capability of shearing machines becomes even more critical. By ensuring the sheet remains flat after cutting, it facilitates subsequent handling, storage, and further processing operations, avoiding problems such as the need for re-leveling or increased processing difficulties due to sheet deformation.
