CNC bending machines represent the most sophisticated variation, utilizing multi-axis control (Y1/Y2 for ram synchronization) and incorporating 3D simulation software. They also have automatic tool changers (setup time <10min) and laser angle sensors that allow for a complex feedback loop with high precision (feedback accuracy ±0.1°), enabling the machine to support intricate multi-bend parts such as multi-bend 20+ truck frames. These are critical in aerospace sheet metal fabrication; they have maximum bending lengths of 6000mm and therefore first-pass yield rates >95%.
