A CNC press brake from Anhui Zhongrui Machine Tool Manufacturing Co., Ltd. operates through a precise blend of mechanical engineering and computer control. The process begins with the CNC system receiving design data from CAD software, which defines bend angles, sequences, and tool paths. The machine’s hydraulic or electric drive system powers the ram, which descends to apply force to the sheet metal clamped between the punch and die. Key components like the backgauge position the material accurately, while sensors monitor ram position, force, and bend angle in real time. Zhongrui’s advanced models integrate adaptive algorithms that compensate for material springback, ensuring precision. The hydraulic systems in their heavy-duty presses use proportional valves for smooth force control, while electric models rely on servo motors for energy-efficient, high-speed operation. This combination of automated control and mechanical precision allows the CNC press brake to transform flat metal sheets into complex 3D shapes with micron-level accuracy.
