Q1. How do I choose the right tonnage for a CNC press brake?<\/strong><\/p>\n\n\n\n

The required tonnage depends on the material type, sheet thickness, bending length, tensile strength, tooling and bending method. Thicker and stronger materials generally require greater bending force, while longer bends usually require more tonnage.<\/p>\n\n\n\n

To select the right machine, consider your maximum material thickness and bending length, as well as your typical production requirements. RAGOS can evaluate your application and recommend a suitable press brake based on your workpiece specifications and technical drawings.<\/p>\n\n\n\n

Q2. Can a press brake bend 8 mm steel plate?<\/strong><\/p>\n\n\n\n

Yes, provided the press brake has sufficient rated capacity for the material, bending length and selected tooling. However, the required tonnage for an 8 mm plate varies significantly depending on whether the bend is short or extends across a longer workpiece.<\/p>\n\n\n\n

Material strength, V-die opening, flange dimensions and bending method must also be considered. Before selecting a machine, provide the material grade, plate thickness, bending length and workpiece drawing for a technical assessment.<\/p>\n\n\n\n

Q3. What press brake tonnage is required for 3 mm mild steel?<\/strong><\/p>\n\n\n\n

The required tonnage depends primarily on the bending length, material properties and tooling. A 3 mm mild-steel sheet bent over a short section requires less force than the same material bent across a longer length.<\/p>\n\n\n\n

For example, if your application involves a 2,400 mm workpiece, the machine should be evaluated for the full required bending length rather than thickness alone. Share your material specifications and drawings to determine the appropriate machine capacity.<\/p>\n\n\n\n

Q4. What press brake do I need for 8 mm steel plate?<\/strong><\/p>\n\n\n\n

Selecting a press brake for 8 mm steel requires more information than plate thickness alone. The machine must provide sufficient tonnage and working length for the intended bends, while the tooling must be suitable for the material and required bend geometry.<\/p>\n\n\n\n

The key details are material grade, maximum bending length, V-die opening, flange dimensions and production requirements. RAGOS can use these details to assess suitable machine configurations before you request a quotation.<\/p>\n\n\n\n

Q5. How does bending length affect the required tonnage?<\/strong><\/p>\n\n\n\n

For the same material, thickness, tooling and bending method, the required bending force generally increases with bending length. This means a machine that can bend a particular thickness over a short section may not have enough capacity to bend it across the full working length.<\/p>\n\n\n\n

When selecting a press brake, consider the longest bend you need to produce, not just the largest sheet dimension. The rated tonnage and working length must both match the application.<\/p>\n\n\n\n

Q6. Should I choose a 130-ton or 170-ton press brake?<\/strong><\/p>\n\n\n\n

The decision depends on the thickest material you process, the maximum bending length, material strength, tooling and expected future production needs. A 170-ton machine offers greater nominal force capacity, but the extra capacity may not be necessary for every application.<\/p>\n\n\n\n

Compare the actual bending requirements against each machine’s rated capacity and configuration. If you provide your material thickness, bending length and representative workpiece drawings, RAGOS can help evaluate which option is more appropriate.<\/p>\n","protected":false},"excerpt":{"rendered":"
