Cutting Capacity

Cutting capacity is the intersection of machine size, blade length, and hydraulic or mechanical force that defines what materials and thicknesses can be processed on a given shear. A small manual shear might be rated for 10 gauge mild steel across a 3-foot width, while a large industrial CNC shear could handle 3/16-inch steel across 6 feet or more.

Selecting the right equipment for a job depends on accurately understanding both the material grade (which affects shear strength) and the gauge (thickness), because exceeding a machine's rated capacity can result in incomplete cuts, blade breakage, and machine damage. Fabricators must also consider that cutting thicker material at the edge of the machine's capacity often produces heavier burr and worse squareness than cutting in the middle of the bed, so understanding machine limitations is critical for quality planning.
