China CNC Press Brake Machines for Precision Sheet Metal Bending
Rucheng manufactures CNC press brakes, hydraulic press brakes, tandem press brakes and robotic bending systems for factories that need stable angle accuracy, repeatable back gauge positioning, practical export support and clear machine quotations.
Choose the press brake that matches your bending work
A press brake should be selected from real parts, not only from a requested tonnage number. Rucheng helps buyers compare bending length, force, controller, back gauge axes, crowning, tooling and automation level before quoting.
Electro-hydraulic CNC Press Brake
Servo-hydraulic Y1/Y2 control for accurate, repeatable sheet metal bending.
Torsion-synchro NC Press Brake
Cost-effective hydraulic bending machine for standard parts and stable batches.
Tandem Press Brake
Two synchronized press brakes for long profiles, poles, panels and heavy workpieces.
Heavy-duty Press Brake
High tonnage bending for thicker plate, large structures and demanding production.
Robotic Press Brake
Automated loading, bending and unloading for repeat parts and labor reduction.
China press brake manufacturer quote factors
A press brake machine price is driven by tonnage, working length, CNC controller, back gauge axes, crowning, tooling, safety system and automation. Use this guide to prepare a clearer factory quotation request.
Cost-sensitive standard bending
NC torsion-synchro press brakes and entry CNC press brakes fit buyers who need reliable hydraulic bending for repeated parts, simple profiles and controlled budgets.
Precision CNC production
Electro-hydraulic CNC press brakes add Y1/Y2 control, better repeatability, graphical programming, crowning and stronger back gauge options.
Custom heavy or automated work
Tandem systems, heavy-duty press brakes and robotic press brake cells require quotation from drawings, material handling, cycle targets and tooling requirements.
How to specify a press brake machine
The right machine is a production decision. Send drawings, material thickness range, maximum bending length, annual output, accuracy target and available workshop power. Rucheng engineers can then recommend tonnage, working length, controller, axes, crowning and tooling.
Key buying factors
- Bending force calculated from material, thickness, V-die opening and bend length.
- Working length sized for the longest parts, with handling space around the machine.
- CNC controller and back gauge axes matched to part complexity and batch changeover.
- Mechanical or hydraulic crowning selected for straight angles across the full bend.
- Tooling library planned for V-dies, punches, gooseneck tooling and segmented tools.
- Safety devices, operator training and maintenance access included from the start.
Operation, Safety, Maintenance and Comparison Guides
After selecting a press brake machine, use these guides to train operators, compare machine types, plan maintenance and avoid common setup problems.
Press brake tonnage and length starting points
Use these ranges as a first discussion guide. Final sizing must be calculated from the actual material grade, thickness, bend length, V-die opening, inside radius, flange length and production reserve.
Light sheet metal
Cabinets, covers, trays and brackets in 0.8-3 mm sheet usually start from 40T to 100T, depending on bend length and material.
General fabrication
Most 3-6 mm mild steel work uses 100T to 250T machines with 2500-4000 mm working length and suitable crowning.
Heavy or long parts
Long panels, poles, structural parts and thick plate may need heavy-duty or tandem press brakes with custom tooling and handling plans.
| Work requirement | Starting machine class | Typical configuration | Confirm before quote |
|---|---|---|---|
| Thin sheet, short bends, small batches | 40T-63T | NC or compact CNC press brake, 1600-2500 mm | Low-tonnage precision, tooling size and operator workflow |
| 2-4 mm mild steel cabinets and enclosures | 80T-160T | CNC hydraulic press brake, 2500-3200 mm, crowning recommended | Maximum bend length, controller, back gauge axes and V-die set |
| 4-8 mm plate, stainless or high-strength parts | 160T-320T | Heavy CNC press brake, 3200-4000 mm or custom length | Tensile strength, springback, die opening, radius and machine reserve |
| Long profiles, poles, doors and panels | Tandem or custom length | Two synchronized machines or long-bed press brake | Foundation, material handling, synchronization and safety zone |
Press brake type comparison
Use this table as a first filter. The final specification should still be confirmed from part drawings, material standards and production targets.
| Machine type | Best for | Main advantages | Common buyer focus |
|---|---|---|---|
| CNC hydraulic press brake | High-mix factories, cabinets, enclosures, panels and precision brackets | Y1/Y2 control, programmable back gauge, better repeatability, easier setup | Controller, axes, crowning, tooling and accuracy |
| NC torsion-synchro press brake | Standard bending jobs and buyers with tighter budgets | Simple structure, lower cost, reliable for repeat parts | Tonnage, length, back gauge and operator workflow |
| Tandem press brake | Long poles, doors, panels, channels and structural parts | Extended bending length, synchronized operation, flexible single or tandem use | Synchronization, foundation, handling equipment and safety zone |
| Robotic press brake cell | Repeat parts, high labor cost plants and stable production programs | Automated handling, consistent cycle, reduced manual loading | Part variety, robot reach, grippers, offline programming and payback |

Press brake machine questions
What is a press brake machine?
A press brake machine bends sheet metal by pressing the workpiece between an upper punch and a lower die. It is commonly used for cabinets, brackets, enclosures, panels, channels and many custom sheet metal parts.
How do I choose the right press brake tonnage?
Tonnage depends on material type, thickness, bend length, tensile strength and V-die opening. Share your drawings and thickness range so the machine can be sized with enough working margin.
Should I buy a CNC press brake or an NC press brake?
Choose a CNC press brake for high-mix production, tighter tolerances, complex parts and frequent program changes. An NC torsion-synchro press brake can be a practical choice for simpler parts, standard batches and lower budgets.
How much does a CNC press brake machine cost?
CNC press brake price depends on tonnage, working length, controller, back gauge axes, crowning system, tooling, safety devices and automation. Small machines are lower cost, while tandem, robotic and heavy-duty configurations require custom quotations from drawings and production requirements.
Is Rucheng a China press brake manufacturer?
Yes. Rucheng manufactures and supplies CNC hydraulic press brakes, NC press brakes, tandem press brakes, heavy-duty press brakes, robotic bending cells, tooling and related sheet metal fabrication equipment from China for export buyers.
Can Rucheng customize press brake specifications?
Yes. Rucheng can recommend and configure tonnage, working length, controller, back gauge axes, crowning, tooling, safety system and automation options according to your production requirements.
What press brake size do I need for 3 to 6 mm sheet metal?
For common mild steel work, 3 mm sheet over 2 to 3 meters often fits the 100 ton class, while 4 to 6 mm sheet usually needs 160 to 250 tons depending on bend length, V-die opening and material grade. Calculate from the actual drawing and keep 20 to 30 percent reserve.
What information should I send for a press brake quote?
Send material grade, thickness range, maximum bend length, required inside radius, minimum flange length, bend angles, annual output, accuracy requirement, workshop voltage and any preferred controller, back gauge, crowning or tooling requirements.
Send drawings for a practical press brake recommendation
Include material, thickness range, maximum bend length, annual output, tolerance target and workshop voltage. Rucheng will recommend a press brake configuration and quotation based on your actual bending work.
