Start With the Parts You Make
Different bending jobs need different press brake configurations. Start with the parts you make, then match the machine tonnage, bending length, CNC axis, tooling and crowning system around your work.
Electrical Cabinets
For control boxes, switchgear panels and cabinet doors, focus on CNC control, repeatable backgauge positioning, suitable tooling and stable multi-bend programs.
Sheet Metal Enclosures
For boxes, covers and enclosure parts, check flange height, punch clearance, bending sequence and backgauge space before selecting the machine.
HVAC Ducts & Covers
For ducts, flanges and light sheet metal parts, focus on thin sheet bending, fast setup, simple operation and repeatable angle control.
Stainless Steel Parts
For stainless steel bending, consider tooling selection, surface protection, springback, bend radius and angle adjustment.
Heavy Brackets
For thicker plates and structural parts, focus on tonnage, frame rigidity, die opening, tooling strength and safe bending capacity.
Long Panels
For long panels and wide sheet metal parts, bending length and crowning are important for keeping angles more consistent across the full workpiece.
Small Batch Fabrication
For mixed products and frequent job changes, program storage, segmented tooling, quick clamping and repeatable backgauge positioning help reduce setup time.
Custom Metal Parts
For custom parts, send drawings, material, thickness, bend angles and flange sizes. We help you check the bending process before recommending a machine.
Tell Us What You Bend, We Spec the Machine
Send your material, thickness range, flange sizes and daily volume. You get a clear recommendation on tonnage, bending length, CNC axis, crowning and tooling, matched to your real parts instead of a generic catalog spec.
Match the Machine to Your Regular Work
The right press brake should match your regular bending work, not only the maximum thickness you may bend once in a while.
Tonnage and bending length should be selected according to material type, tensile strength, sheet thickness, bend length, V-die opening, flange size, bend angle and tooling choice.
If the tonnage is too small, the machine may be overloaded during thick plate or long workpiece bending. If the machine is too large, it may raise cost, floor space and energy use without improving your daily production.
What Affects Press Brake Tonnage?
Material Type
Carbon steel, stainless steel, aluminum and high-strength steel need different bending force. Higher tensile strength usually requires higher tonnage.
Sheet Thickness
Thicker sheet metal needs more bending force. Thickness tolerance should also be considered, especially for batch production.
Bending Length
Longer bends need more total force. A short part and a full-length panel with the same thickness may need very different capacity.
V-Die Opening
A smaller V opening usually requires higher tonnage. A larger V opening can reduce bending force, but it also affects inside radius and minimum flange size.
Regular Work Range
Your machine should fit the materials and thicknesses you bend most often. Occasional maximum work should be checked separately.
Future Production
If your product range may include longer panels, thicker plates or new materials, leave a practical capacity margin during selection.

Position Every Bend Right the First Time
The backgauge helps you position the sheet before each bend. The right CNC axis configuration depends on your part shape, flange size, bending sequence and repeat production needs.
More axes are not always necessary. A simple part may only need basic backgauge control, while cabinet parts, enclosure parts and asymmetrical workpieces may need more flexible positioning.
Choose by Your Bending Need
| Your Bending Need | Backgauge Focus |
|---|---|
| Simple straight bends | Basic X-axis positioning |
| Different flange heights | X and R axis control |
| Cabinet and enclosure parts | Repeatable positioning and program storage |
| Asymmetrical parts | Z1/Z2 finger adjustment |
| Tapered or special parts | Independent backgauge movement |
| Multi-bend parts | CNC program control and bending sequence |
| Batch production | Repeat positioning and saved programs |
Common Axis Functions
Each axis adds a different kind of positioning control. Here is what each one does and when you need it.
Front & Back Movement
Controls the front and back movement of the backgauge. You use it to set the flange length before bending.
Up & Down Movement
Controls the up and down movement of the backgauge. It helps you position parts with different flange heights or step bends.
Left & Right Fingers
Controls the left and right movement of the backgauge fingers. Useful for different part widths, asymmetrical parts and flexible positioning.
Independent Fingers
Allows independent front and back movement of the backgauge fingers. Used for special positioning needs, tapered parts or more complex bending work.
Pick the Axis Setup That Fits Your Parts
Send your part drawings, flange sizes and bending sequence. We help you check which axis configuration is suitable before you choose the machine, so you pay for the control you actually use.
Mostly simple straight parts
A basic CNC backgauge may be enough for your work.
Cabinets, boxes & mixed flange heights
R axis and adjustable fingers make your setup easier.
Mixed products, asymmetrical parts & small batches
A multi-axis backgauge cuts manual adjustment and improves repeatability.
Keep Long Bends Consistent End to End
Long workpieces are more likely to show angle difference between the center and both ends of the bend.
During bending, the press brake frame and worktable can deflect under load. This can change the working depth between the punch and die, especially on long panels or thicker plates.
A crowning system helps compensate for this deflection, so the bending force is distributed more evenly across the full length of your workpiece.
When Crowning Is Recommended
Long Panels
If you often bend wide doors, covers, cabinet panels or long sheet metal parts, crowning helps you improve angle consistency from end to end.
Thick Plates
Higher bending force can create more deflection. Crowning becomes more important when you work with thicker carbon steel, stainless steel or structural parts.
Batch Production
When the same long part needs to be produced repeatedly, crowning helps you reduce angle variation and repeated manual adjustment.
Higher Accuracy Work
For cabinets, enclosures and visible panels, small angle differences can affect assembly and appearance. Crowning helps you keep bending results more consistent.
Crowning Options
Mechanical crowning and hydraulic crowning can be selected according to machine size, bending length, tonnage and your production requirements.
For short parts or simple light sheet bending, crowning may not always be necessary. For long bends, thicker plates or parts that need stable angle consistency, it should be checked during machine selection.
Tooling Determines What You Can Bend
A press brake is not selected by machine size alone. The punch, die, V opening, tooling height and clamping method directly affect what parts you can bend.
Many bending problems start from tooling mismatch. A machine may have enough tonnage, but the part still may not bend correctly if the tooling does not match the material, flange size, bend radius or part shape.
Tooling Points to Check
Punch Type
Straight punch, gooseneck punch and special punch shapes are used for different bending jobs. Box parts, deep flanges and return bends may need more clearance.
Die Opening
The V-die opening affects bending force, inside radius and minimum flange size. A smaller opening needs more force, while a larger opening changes the bend radius.
Bend Radius
The inside bend radius should match the material, thickness and product requirement. Tooling selection can directly change the final bend radius.
Small Flanges
Short flange parts need careful checking. The flange may be too small for a standard die opening or backgauge positioning.
Box Bending
Cabinets, enclosures and box parts may hit the punch, tooling or machine frame during multi-step bending. Tooling shape and bend sequence should be checked before selection.
Surface Protection
Stainless steel, aluminum and visible panels may need tooling protection, film, special dies or careful setup to reduce surface marks.
Tooling Built Around Your Drawings
Send your part drawings and bending process. We help you select the punches, dies and clamping setup that fit your products, so changeovers stay fast and your bends stay repeatable.
Segmented Tooling
Helps with box bending, small batches and flexible part sizes.
Quick Clamping
Cuts tool change time when you switch between different products.
Special Punches & Dies
Hemming tools, gooseneck tools and special punches selected to match your drawings and bending process.
Different Materials Bend Differently
Different materials do not bend in the same way. Material strength, thickness tolerance, grain direction, surface condition and springback can all affect your final bending angle.
Even with the same press brake and the same program, your bending results may change when the material type, thickness, batch or tooling setup changes.
Common Material Points
Carbon Steel
Widely used for cabinets, brackets, frames and general sheet metal parts. Tonnage, die opening and bend radius should be selected by thickness and bending length.
Stainless Steel
Usually needs more bending force than mild steel at the same thickness. It also has stronger springback and may need surface protection for visible parts.
Aluminum
Easier to bend in many cases, but bend radius, surface marks and cracking risk should be checked, especially for decorative or visible panels.
Galvanized Sheet
Needs careful tooling and setup to reduce surface damage. Coating condition and bend radius should be considered before production.
High-Strength Steel
Needs higher bending force and may show stronger springback. Tooling strength and safe bending capacity should be checked before selection.
Stable Angles Come From a Matched Setup
Bending angles may change because of material springback, thickness variation, tensile strength difference, tooling wear, V-die opening, operator setup or machine calibration.
For stable bending, the machine, tooling and CNC program should be matched with the actual material you use most often. Tell us what you run, and we help you set that up correctly.

Press Brake Questions, Answered
Common questions on tonnage, bending length, CNC axes, crowning, tooling and what to send for a recommendation.
How do I choose the right press brake tonnage?
Press brake tonnage should be selected according to material type, tensile strength, sheet thickness, bending length, V-die opening and bend angle. Do not choose tonnage only by the maximum thickness. Your regular bending work should be the main reference, while occasional heavy work should be checked separately.
How do I choose the right bending length?
The bending length should cover your common part size and the maximum workpiece length you need to bend. If you often bend long panels, cabinet doors or wide covers, you should also check machine rigidity, crowning and handling space, not only the nominal bending length.
Is a larger press brake always better?
No. A larger machine may increase cost, floor space, energy use and setup difficulty. The better choice is a machine that fits your regular material range, part size, tooling needs and production volume, with a practical capacity margin for future work.
How many CNC axes do I need?
It depends on your part shape and positioning needs. Simple straight bends may only need basic backgauge control. Parts with different flange heights may need X and R axes. Cabinets, enclosures, asymmetrical parts and multi-bend parts may need Z-axis fingers or more advanced backgauge control.
When is crowning necessary?
Crowning is recommended for long bends, thicker plates and parts that need better angle consistency across the full workpiece. During bending, the frame and worktable can deflect under load. Crowning helps compensate for this deflection and reduce angle difference between the center and both ends.
Why do bending angles change between different materials?
Different materials have different tensile strength, thickness tolerance and springback. Stainless steel, aluminum, galvanized sheet and high-strength steel may not bend the same way as carbon steel. Even with the same program, the angle may change when the material batch, thickness or tooling setup changes.
What tooling do I need for my parts?
Tooling should be selected according to material thickness, bend radius, flange height, part shape and surface requirements. Box parts may need gooseneck or segmented tooling. Small flanges need the correct V opening. Stainless steel or visible panels may need surface protection during bending.
Can one press brake handle different products?
Yes, if the machine capacity, controller, backgauge and tooling are selected properly. For mixed products and small batches, program storage, repeatable backgauge positioning, segmented tooling and quick clamping can make job changes easier.
Why should I send part drawings before choosing a machine?
Drawings help check bending length, flange size, bend angle, inside radius, tooling clearance, possible interference and bending sequence. Some parts may look simple, but the tooling or backgauge setup can affect whether they can be bent smoothly.
What information should I send for a press brake recommendation?
Please send material type, thickness range, maximum bending length, part drawings, bend angles, flange height, required inside radius, production volume and any current bending problems. These details help us check tonnage, machine length, CNC axis, crowning and tooling direction.
