The operation of machine shears involves two primary components the upper blade and the lower blade
. The upper blade (or moving blade) applies a downward force, effectively compressing the material against the lower, stationary blade. When the force exceeds the material's shear strength, it causes the material to fracture along the line of cut. The angle of the blades, the speed of the cut, and the type of material being sheared are crucial factors that influence the quality of the cut and the finish of the edges.Another significant benefit is the reduction of material waste. CNC roll forming machines optimize the use of raw materials by maximizing the number of profiles produced from a single sheet. This not only lowers costs but also contributes to more environmentally friendly manufacturing processes by minimizing excess waste. Furthermore, the precise nature of CNC controls ensures that dimensions are accurate, which significantly reduces the need for rework or scrap.
