At its core, the CNC shear machine operates by employing a shearing mechanism that consists of a fixed blade and a moving blade. When metal sheets are placed between these blades, the machine applies force to cut through the material. The CNC element comes into play through programmed instructions that dictate the movement and operation of the blades based on the desired shapes and dimensions. With the aid of CAD (Computer-Aided Design) software, operators can design intricate patterns and geometries, which the CNC shear then replicates with remarkable accuracy.
