PDS Series Servo Hydraulic CNC Press Brake Machine For Sheet Metal

The PDS Series is an advanced electro-hydraulic hybrid CNC press brake designed for high-efficiency metal bending. By utilizing a dedicated servo motor to control the hydraulic pump, it delivers over 50% energy savings, lower oil temperatures, and superior motion dynamics. Built with an overall tempered, ultra-rigid welded frame and equipped with a premium closed-loop synchronization system, the PDS series ensures unmatched durability, precise bending angles, and seamless operation for customized fabrication.

            

  • Hybrid Servo Drive: Electro-hydraulic system saves over 50% energy.
  • ±0.02mm Precision: German Rexroth closed-loop synchronization control.
  • Ultra-Rigid Frame: Welded and overall heat-treated bed for zero deformation.
  • Smart DELEM Control: DA-53TX 15.6" touchscreen for intuitive programming.
  • World-Class Parts: Built with ESTUN servos, Schneider electronics, and Parker seals.

  • Q: Is a multi-axis backgauge (e.g., 4+1, 6+1, 8+1) worth the investment?
  • A: A standard 4+1 axis (Y1, Y2, X, R + Crowning) handles ~80% of regular square parts. However, for stepped flanges, tapered/asymmetric parts, and multi-station staging setups, DADONG's 6+1 or 8+1 axis backgauge (with independent X1-X2 fingers and motorized Z1-Z2) positions automatically—slashing handling setup time by over 50%.
  • Q: Can the machine handle deep boxes and complex U-channels without tool collision?
  • A: Yes. DADONG provides 3D Offline Simulation & Bending CAM Software. Before running the machine, you simply import your STEP file: 1) It auto-determines optimal bending sequences; 2) Recommends tooling setups; 3) Performs 100% virtual collision detection. Furthermore, we offer customized extended daylight openings, deeper throat depths, and specialized gooseneck/window tools.
  • Q: Why does the middle angle deviate from the ends on long bending parts (2.5m–4m), and how is it fixed?
  • A: This is caused by natural structural deflection under high pressure. DADONG press brakes feature CNC-Controlled Automatic Mechanical Crowning. The CNC calculates the precise deflection curve based on material properties, sheet thickness, and length, driving high-precision motorized wedges to dynamically compensate across the bed—ensuring uniform ±0.2° angle consistency from end to end.
