What Key Parameters Do Customers Care About When Choosing a CNC Hydraulic Press Brake?

1. Why Are Parameters So Important?

The performance and productivity of a CNC hydraulic press brake heavily depend on how well the machine’s parameters match the application. Selecting the wrong configuration can result in tool damage, material waste, or inadequate bending precision. That's why customers pay close attention to critical technical specs before purchasing.

2. Most Important Parameters Customers Consider

1. Press Force (Tonnage)

   • Determines the maximum force applied to the material. Must match material thickness and die opening.

   • Common range: 40T to 600T. Heavy-duty applications often require 400T or more.

2. Bending Length (Table Length)

   • Indicates the maximum length of metal sheets that can be bent in one go.

   • Common lengths: 2500mm, 3200mm, 4000mm, 6000mm.

3. Distance Between Uprights (Column Gap)

   • Refers to the usable space for the workpiece, usually less than the full table length.

4. Throat Depth

   • Allows for bending return flanges or closed profiles. Essential for complex part designs.

5. Stroke and Open Height

   • A longer stroke enables deep bends; larger open height allows for thicker dies and taller parts.

6. CNC Control System (e.g., Delem DA-52S, ESA, Cybelec)

   • Affects user experience, graphical programming, multi-axis control, and crowning compensation.

7. Back Gauge System (X, R Axis)

   • High-precision backgauge helps with repeatable, multi-step bending and faster cycle times.

8. Hydraulic and Synchronization System

   • Look for systems with crowning compensation and electro-hydraulic synchronization for consistency.

9. Tooling and Clamping System

   • Check for compatibility with fast clamping systems and support for Promecam or WILA standards.

10. Brand and After-Sales Support

• Reliable brands provide better durability, and strong after-sales service ensures less downtime and maintenance cost.

3. Final Advice

When selecting a CNC press brake, don’t focus solely on price. Ensure the parameters fit your production requirements and provide flexibility for future expansion. A well-matched machine pays off in productivity, accuracy, and long-term stability.
