Overview
Key Product Details: Quick Specs and Bending Capacity
Our 300 ton CNC press brake delivers heavy-duty forming power for thick plate processing, structural steel production, and precision sheet metal fabrication. Designed to handle intense daily bending cycles, this machine pairs substantial tonnage with micron-level electro-hydraulic positioning.
Pressing Force Rating and Structural Integrity
The rated 3,000 kN (300 metric tons) bending force provides ample tonnage for heavy gauge plate bending. We fabricate the machine body from high-tensile, stress-relieved welded steel plate, ensuring zero structural deflection during peak load operations. Heavy side housings and deep bed sections maintain structural alignment, protecting long-term tooling accuracy under full tonnage runs.
Working Length and Distance Between Uprights
The standard working table length spans 4,000 mm (approx. 13 feet), providing versatile capacity for long workpieces or multi-stage side-by-side bending setups. The clear distance between the side frames measures 3,200 mm, giving operators wide lateral clearance to handle deep side flanges and wide sheets without interference.
Throat Depth, Open Height, and Stroke Parameters
Clearance dimensions allow full flexibility for complex box profiles, deep channels, and high-return flanges:
-
- Throat Depth: 400 mm deep side frame gap for off-center flange bending.
- Open Height (Daylight): 550 mm standard opening between upper ram and lower table.
- Stroke Length: 250 mm vertical travel, enabling the use of tall punches and deep multi-V dies.
CNC Control System and Standard Axis Configuration
The machine integrates standard 4+1 axis CNC automation (Y1, Y2, X, R, plus V-axis mechanical crowning). Dual independent linear scales mounted on the C-frames track the Y1 and Y2 cylinders directly, feeding real-time position data back to the CNC system. High-speed AC servomotors drive the X-axis backgauge depth and the R-axis vertical finger adjustment with ball screws and linear guideways.
Crowning System, Drive Power, and Electrical Specs
Consistent angle results over long bends require balanced deflection compensation. Our CNC-managed dynamic crowning table automatically adjusts lower bed deflection based on material thickness, yield strength, and target bend angle.

Heavy-Duty Bending Performance: 300 Ton CNC Press Brake
How the Electro-Hydraulic System Operates
At the core of this machine is an advanced electro-hydraulic synchronous setup:
-
- Dual Cylinder Control (Y1/Y2): High-response proportional valves continuously adjust oil flow to both cylinders independently, guided by high-precision optical linear encoders.
- Closed-Loop Real-Time Balancing: If the ram encounters uneven resistance during off-center loading, the system corrects tilt within fractions of a millisecond.
- Energy-Efficient Hydraulics: Large-flow pre-fill valves enable rapid ram approach, smooth high-pressure bending, and fast return cycles to keep cycle times down.
Core CNC Automation and Multi-Axis Backgauge Capabilities
Bending heavy sheet metal requires reliable sheet positioning without constant manual readjustment. For shops processing complex geometric profiles, stepping up to a 6-axis CNC press brake bending machine ensures absolute positioning freedom.
-
- Multi-Axis Backgauge: Controlled movement across standard X and R axes, with optional Z1/Z2 or independent X-prime axes for tapered bends.
- Dynamic CNC Crowning: The controller reads the sheet thickness, tensile strength, and bending length, automatically applying bed deflection compensation before the ram touches the metal.
- Automated Bending Sequences: The operator inputs the profile dimensions, and the controller computes the bend order, backgauge stops, and required tonnage on the fly.

Core Features and Mechanical Build

Heavy-Duty Welded Steel Frame with Stress Relief
The backbone of our 300 ton CNC press brake for sale is a monolithic, heavy-duty welded steel frame.
Thermal Stress Relieving: After welding, the entire frame undergoes complete thermal annealing in a dedicated furnace to eliminate internal residual stresses.
Rigid Bed Deflection Resistance: Thick side housings and deep bed beams prevent structural fatigue and maintain throat integrity under continuous full-tonnage cycles.
Precision Machined Surfaces: Critical mounting points for guide rails, cylinders, and tables are machined in a single setup on large CNC gantry milling centers to guarantee absolute parallelism.
Electro-Hydraulic Synchronous Valve System
Our machines utilize a closed-loop electro-hydraulic synchronous press brake design. Independent proportional valves govern the twin cylinders (Y1 and Y2 axes) in real time:
High-Precision Leveling: High-resolution optical linear scales continuously track ram positioning on both sides, feeding data back to the CNC controller.
Off-Center Bending Protection: The dynamic hydraulic valves automatically correct for uneven loads, allowing off-center bending without twisting the ram or damaging cylinder seals.
Smooth Transitions: Fast approach, controlled pressing, and high-speed return cycles operate seamlessly with rapid valve response times.
This stable hydraulic synchronization establishes this unit as our best CNC press brake for precision metal forming, especially when processing thick, high-tensile plates.
High-Speed Multi-Axis CNC Backgauge
Repeatable flange lengths rely on an uncompromising gauge assembly. We equip every 300t unit with a high-rigidity backgauge built to handle heavy stock without drifting:
Precision Drive System: High-speed, ground ball screws paired with dual linear guide rails eliminate mechanical backlash on the X and R axes.
AC Servo Motors: High-torque digital servo drives deliver rapid positioning speeds, significantly cutting cycle times between bends.
Adjustable Gauge Fingers: Multi-level stop fingers feature hardened contact surfaces and smooth manual or automated Z-axis adjustment across the work area.
Automatic CNC Crowning Compensation
To eliminate angle variance along long bends, our integrated multi-axis CNC crowning system counters natural frame and bed deflection:
Real-Time Angle Correction: The controller calculates plate thickness, material yield strength, and target bend length, dynamically adjusting the crowning wedges.
Consistent Flange Profile: Delivers a straight, uniform bend angle from the outer edges straight through the center of the bed.
Hydraulic or Mechanical Options: Available with motorized mechanical wave-block systems or integrated hydraulic bed cylinders to match your tooling preferences.
Fast Manual and Hydraulic Quick-Clamping Systems
Minimizing setup time between production runs keeps your machine operating profitably:
Standard Quick-Clamping: Mechanical quick-release clamps let operators load and seat punches vertically, eliminating slow horizontal slide-ins.
Optional Hydraulic Clamping: Push-button hydraulic clamping locks standard and European-style segmented tooling instantly across the entire upper beam.
Multi-V Lower Die Centering: Precision-ground table channels provide fast, accurate centering of single-V or multi-V dies.

Frequently Asked Questions
What material thickness can a 300 ton CNC press brake bend?
A 300 ton CNC press brake handles mild steel, stainless steel, and aluminum across varied thicknesses based on your working length and die opening (V-width). Across a typical 3200 mm to 4000 mm bed, this capacity covers medium-to-heavy plate fabrication.
| Material Type | Typical Max Thickness (Full Bed) | Typical Max Thickness (Shorter Lengths) | Recommended V-Opening |
|---|---|---|---|
| Mild Steel | 6 mm – 8 mm (1/4" – 5/16") | 10 mm – 12 mm (3/8" – 1/2") | 8x material thickness |
| Stainless Steel | 4 mm – 6 mm | 8 mm – 10 mm | 10x – 12x material thickness |
| Aluminum | 8 mm – 10 mm | 12 mm – 16 mm | 6x – 8x material thickness |
For lighter sheet metal work or thin-gauge jobs requiring high speed and lower energy draw, shops often alternate between heavy hydraulic equipment and specialized servo-electric press brakes to maximize workflow efficiency.
Why is an automatic crowning system necessary on a 300-ton machine?
High tonnage causes natural mechanical deflection along the center of the bed and ram. Without compensation, parts end up with uneven bend angles: correct on the ends, under-bent in the center. An automatic CNC crowning system hydraulically or mechanically counters this deflection in real time, delivering uniform angles across the entire workpiece.
Which CNC controller is best suited for my bending operations?
The ideal controller matches your team's programming workflow:
Basic 2D entry (e.g., Delem DA-53T / Cybelec CybTouch): Best for standard sheet metal parts, fast direct programming, and straightforward jobs.
Advanced 2D/3D graphical (e.g., Delem DA-58T / ESA S640): Great for multi-bend sequencing, automatic tooling clash detection, and shop-floor flexibility.
High-end 3D offline simulation (e.g., Delem DA-66T or DA-69T): Designed for complex heavy-plate forming, direct CAD/CAM file imports, and automated bend-step calculation.
What are the foundation and electrical requirements for setup?
-
- Foundation: A reinforced concrete industrial pad is mandatory. Standard slab thickness ranges from 200 mm to 300 mm (8"–12") depending on soil bearing capacity to handle heavy dynamic loads without settling.
- Electrical: Standard setup runs on 380V–480V 3-phase power, 50/60 Hz. The main hydraulic drive motor typically demands 22 kW to 30 kW, requiring a dedicated breaker and clean electrical grounding.
What is the expected delivery timeline for a custom configuration?
-
- Standard Build in Stock: 2 to 4 weeks for factory checks, packaging, and dispatch.
- Custom Engineering (special throat, extended stroke, multi-axis backgauges): 6 to 10 weeks manufacturing lead time prior to ocean freight.
