All electric press brakes from DURMAPRESS deliver breakthrough capabilities for fabricators processing long workpieces such as electrical cabinets, door frames, and industrial enclosures. These CNC electric press brakes achieve superior bending lengths through optimized frame geometry and servo-driven precision, overcoming traditional hydraulic limitations while slashing energy costs.
Extended Bending: All Electric Innovation
Fabricators frequently face challenges bending workpieces over 3 meters on conventional hydraulic press brakes, where frame deflection causes angle inconsistency and requires labor-intensive segmental bending followed by welding. DURMAPRESS all electric press brakes address these pain points with significantly wider side-frame distances and rigid construction that maintain structural integrity across extended lengths—often exceeding 4 meters in single setups.
The attached image clearly illustrates DURMAPRESS's "Maximum Pole Distance" design, which maximizes usable space between uprights for deep U-bending, tall flanges, and complex profiles without interference or repositioning. This all electric press brake innovation eliminates multiple handling steps, reduces material waste, and delivers seamless production for sectors including electrical enclosures, HVAC systems, and heavy machinery covers.
Core Structural Advantages
CNC electric press brakes incorporate advanced engineering specifically for long-bending applications:
Maximum Frame Distance: The enlarged separation between side frames—as highlighted in your machine photo—provides unmatched clearance for oversized sheets and deep-box forming, preventing collisions during complex operations.
All Electric Servo Ball Screw Transmission: Multiple high-torque servo motors drive precision ball screws directly to the ram, ensuring perfectly synchronized force distribution along the entire bending length without hydraulic fluid variability or lag.
Enhanced Throat Depth and Daylight Opening: Deeper throat access combined with taller vertical clearance accommodates large sheet metal returns and multi-step flanging on extended parts, all in one continuous operation.
Finite Element Optimized Frame: Advanced FEA analysis minimizes deflection under maximum tonnage, guaranteeing straight bends even on the longest workpieces.
These all electric press brake features deliver significantly greater effective bending length compared to equivalent hydraulic models.
Precision and Control Across Full Length
The hallmark of CNC all electric press brake technology lies in its closed-loop servo control, achieving positioning accuracy of ±0.01mm and angle repeatability within ±0.5° across the complete bending length. Real-time angle measurement systems continuously monitor and correct springback, while dynamic hydraulic or mechanical crowning automatically compensates for any frame deflection during long bends.
Advanced Support Systems:
Programmable front material arms with hydraulic follow-up maintain sheet stability
Extended multi-finger backgauges (up to 6 axes) precisely position long profiles
Offline programming software simulates entire bending sequences to eliminate trial runs
This precision eliminates end-to-end angle drift common in hydraulic machines, achieving first-pass quality on high-volume production runs.

Fabricators switching to DURMAPRESS all electric press brakes report substantial throughput increases, major energy savings, and significantly reduced scrap rates when processing long parts previously requiring multiple hydraulic machines.
DURMAPRESS Technical Leadership
DURMAPRESS stands at the forefront of CNC electric press brake technology with production-proven models featuring:
Bending lengths from 3.2m to 4.5m with industry-leading frame distances
Rapid approach/return speeds for high throughput
Comprehensive tonnage range with overload protection and ultra-quiet operation
Advanced CNC controls with 2D/3D graphical programming and automatic tool setup
Dramatic energy savings versus hydraulic equivalents
Energy Efficiency and Lifecycle Savings
Unlike hydraulic systems that consume power continuously, CNC electric press brakes only draw energy during actual ram movement. This results in dramatic savings during long-part production cycles:
Major electricity cost reductions
Zero hydraulic oil maintenance (no leaks, disposal, or contamination)
Extended service life with fewer wear components
Clean, oil-free operation ideal for precision manufacturing
Technical Implementation Guide
