SC 16mm Metal Sheet Hydraulic Shearing Machine For Sale

SC 16mm metal sheet hydraulic shearing machine is a heavy-duty sheet metal processing equipment, widely used in steel structures, engineering machinery, pressure vessels, power equipment, shipbuilding, wind power equipment, bridges, mining machinery, automobile manufacturing, rail transportation, and other industries. It can efficiently perform high-precision linear shearing of medium and heavy carbon steel, stainless steel, and low alloy steel sheets.

Compared to swing beam shearing machines, the SC guillotine hydraulic shear adopts an integral welded frame + three-point roller guide rail + hydraulic synchronous drive blade holder structure, resulting in higher rigidity and more stable shearing accuracy, making it especially suitable for mass production of 10-20mm thick plates.
