How to Choose a Press Brake Machine: A Buyer's Checklist
Nine questions to answer before you buy, in the order our engineers ask them.
Buying a press brake is a long-term decision. A well-chosen machine runs for decades; a badly chosen one either struggles with your work or ties up money in capacity you never use. This checklist walks through the questions in the order our engineers ask them.
1. Start with your parts, not the catalogue
Collect drawings or samples of the parts you bend most often, plus the most demanding ones. For each, note:
- Material and grade (mild steel, stainless steel, aluminium, high-tensile)
- Thickness
- Longest bend length
- Number of bends and the smallest flange
- Monthly quantity and batch size
These five facts decide almost everything else.
2. Work out the tonnage
For air bending, the force rises with the square of thickness and in direct proportion to length and tensile strength. Use the press brake tonnage calculator for your thickest regular part, then add about 20% so the machine is not always running at its limit.
Buy for your thickest regular work. A part you make twice a year can often be outsourced or bent in shorter sections, and paying for double the tonnage every day is rarely worth it.
3. Choose the working length
The working length must exceed your longest part. Common Indian sheet sizes are 2500 mm long, so 2500 mm machines are popular; lift and long-panel makers need 3200-4000 mm. Remember that tonnage is spread across the length: a long machine bending short parts at full force can load the tools and ram unevenly, so check with the manufacturer if you plan to do heavy work on short sections.
4. Check throat depth, stroke and open height
- Throat depth limits how wide a flange or panel can pass behind the side frames.
- Open height (daylight) limits how tall a box you can remove after bending, and how tall the tooling can be.
- Stroke must be enough for the punch to clear the formed part.
Box and enclosure makers often need more open height than the tonnage alone suggests.
5. Decide on the control
| Control | Best for |
|---|---|
| Conventional hydraulic | Simple parts, varied one-off work, tight budgets |
| NC / PLC | Repeat parts with a few bends, small to medium batches |
| CNC | Multi-bend parts, large batches, tight tolerances, less-skilled operators |
Our article on CNC vs hydraulic press brakes explains the trade-offs in detail.
6. Plan the tooling
Standard punches and a multi-V die cover most work. Add gooseneck punches for return flanges, segmented punches for boxes, and hemming tools for safe edges. Tooling is a real part of the budget, so include it when comparing quotations.
7. Think about the site
- Floor strength or foundation, especially from 125 T up
- Power supply and electrical panel location
- Crane or forklift access for unloading and heavy dies
- Space in front for sheet handling and behind for the back gauge
8. Compare quotations fairly
Check that each quotation covers the same tonnage, length, stroke, open height, throat, control, axes, crowning, tooling, guarding and scope (delivery, installation, training). The press brake machine price guide lists what to compare.
9. Inspect before dispatch
Where possible, visit the manufacturer, watch your machine run and bend your own material. At Devraj Engineering, buyers are welcome at our Ahmedabad works for exactly this.
