  CNC Press Brake Machine

  Our CNC press brake machines deliver high-precision sheet metal bending with advanced CNC control systems. Available from 40T to 600T for stainless steel, carbon steel and aluminum fabrication.

  Main Features:

  1. The machine body adopts an integral welded steel-plate structure. It is tempered in a large tempering furnace to eliminate deformation caused by welding stress and machining stress, ensuring accuracy retention of the machine tool.
  2. Imported electro-hydraulic servo valves and linear scales from internationally renowned brands form a precise control system.
  3. The ram position feedback accuracy is high; operation is accurate and stable; synchronization performance is good; bending accuracy and ram repeat positioning accuracy are high.
  4. The back gauge adopts a precision CNC back-gauge mechanism with more complete functions.
  5. The hydraulic system adopts an integrated control system, reducing pipeline installation, overcoming oil leakage, ensuring machine operating stability, and giving the machine a simple and neat appearance.
  6. The automatic mechanical deflection compensation mechanism eliminates the influence of ram deformation on workpiece quality. The CNC system automatically adjusts the compensation amount, making operation convenient and accurate.
  7. The CNC system adopts a dedicated press-brake CNC system from Delem of the Netherlands and other brands.

  NC Press Brake Machine

  NC press brake machines provide stable and economical sheet metal bending solutions for small and medium fabrication workshops with simple operation and reliable performance.

  Main Features:

  1. A large floor-type boring and milling machine is used for integral machining of the press-brake frame.

  2. The shaft body is made of forged material, with high rigidity and good elasticity, equipped with a fine-adjustment device, and weak eccentric-load resistance.

  3. Users can customize tooling segments of 10, 15, 20, 30, 50, 100, and 300 cm.

  4. ESTUN or DELEM brand CNC systems are available for users to choose.

  5. Ball screws and linear guideways are used and driven by servo motors, enabling fast and accurate back-gauge positioning.

  6. The stop-finger height adopts an integrated adjustment design and can be manually adjusted.

  7. It improves tooling change speed and increases working efficiency.

  Electric Press Brake Machine

  An electric press brake machine is selected for cleaner operation, lower hydraulic maintenance, efficient energy use, and precision bending of smaller or medium sheet metal parts. It is especially useful when the workshop values accuracy, noise reduction, and stable repeat work.

  Main Features

  1. Suitable for precision brackets, small stainless parts, electrical enclosure components.
  2. Key configuration checks include servo capacity, bending length, stroke and open height.
  3. Available selection focus: compact electric press brake and precision electric press brake.
  4. Final model, voltage, controller, safety system, and options can be confirmed by PREF Group according to the buyer drawings.

  Large Tonnage Press Brake

  Large tonnage press brake is designed for thick plate, long parts, structural fabrication, and applications where a standard press brake does not provide enough force or working length. The buying decision must include machine capacity, foundation, handling, tooling, safety, and transport.

  Main Features

  • Suitable for steel structure parts, heavy machinery components, long plates.
  • Key configuration checks include tonnage calculation, bending length, frame deflection control.
  • Available selection focus: single large-tonnage press brake and custom heavy-duty press brake.
  • Final model, voltage, controller, safety system, and options can be confirmed by PREF Group according to the buyer drawings.
