Want clean, accurate cuts through sheet metal without thermal distortion or scrap?<\/p>\n

Metal shearing can deliver it\u2014and for large runs of straight cut work, it can be a lot cheaper than laser cutting. Included here: the basics of the shearing operation, the type of shearing machine best suited to your material and volumes, achievable tolerances, and how to know whether shearing is viable for your job.<\/p>\n

What Is Metal Shearing? (The Cold-Cut Process Explained)<\/h2>\n

\"What<\/p>\n

<\/p>\n

Metal shearing is a cold-working fabrication process that cuts sheet metal, plate, or strip using two opposing cutting blades pressed past each other under high shear force. No heat is applied to the material, no material is removed, and no chips are created; producing a clean straight cut with very little burr.<\/p>\n

This is a fast, chip free alternative to sawing, laser cutting, or plasma cutting, for straight-line work.<\/p>\n

Named after the dominant stress mode: unlike sawing (which removes material by abrasion) or laser cutting (which melts the workpiece), shearing applies pure shear force<\/strong> until the metal fractures along the blade line. Because the process is entirely mechanical, there is no heat-affected zone (HAZ)<\/strong> \u2014 material structure and hardness remain intact right to the cut edge.<\/p>\n

<\/p>\n

What’s the Difference Between Shearing and Cutting?<\/h3>\n

Shearing and cutting are some times confused, but mechanically they are quite different. Shearing is a matter of applying two forces in opposite directions without removing material, the edge of the workpiece localto the cut fractures off along a path. Cutting, generally speaking, covers the use of saws\u2014which remove chips by abrasion\u2014, laser\u2014the reduction of work pieces by vaporization\u2014and plasma\u2014the destruction of the workpiece by melting and blow-away\u2014all of which involve removal of material.<\/p>\n

Cutting is associated with kerf-loss and thermal effects, shear is free from both of these and therefore the most efficient for straight cut work in sheet\/plate materials.<\/p>\n

\n

Engineering Note: The blade offset (the distance between the upper and lower cutting edge measured horizontally) for all except light metals should usually be kept at 5-10% of the material thickness. The amount of clearance controls the fracture path: insuficent clearance results in the process double-shearing (the second bright zone causes rapid wear of the blades) and excess clearance results in a folding and rolling of the metal rather than shearing.<\/p>\n<\/div>\n
