  • ViN (Virtual Navigator) shows the loading position with a laser beam
  • Automatic sequential bends without operator intervention
  • Weight-reduced tools simplify tool setup

  • Tools with front or rear free geometry offer large free spaces
  • Two automatic pop-up squaring arms
  • Operation from gauging side (large panels)
  • Operation from folding beam side (smaller parts and profiles)
  • Two monitors for front or rear operation
  • Import of CAD file data (STEP, geo, dxf, dwg, etc)
  • Automatic programming of the bending sequences
  • Simulation of the bending sequences already in the office with office software
  • PowerBooster for extreme upper beam clamping forces
  • Intelligent folding beam crowning system
  • Air conditioning unit in the electrical cabinet for extreme outdoor conditions
  • Ideal solution for users with high demands on flexibility


Getting to know the RAS MEGABend

UpDown bending technology

The MEGABend can be operated from the front and from the rear. With the new and double-monitoring safety system, even a front operation with UpDown bending technology is possible.

  • No material flipping required
  • Program controlled folding beam pendulum movement (zero setup time)
  • Passing pre-bent flanges (150 mm folding beam stroke)
  • Deep folding beam (perfect bending accuracy)
  • Quick and easy operation. Short cycle times.
  • Automatic folding sequence per station and part side

Rigid upper beam geometry

  • Extremely rigid box shape upper beam projecting steeply upwards (high bending quality)
  • Large clearance in front of the upper stringer
  • Large clearance behind the upper beam (rear visibility and access)
  • Automatic tool clamping (fast set-up)
  • 3-axis servo drive (fast travel, high clamping forces)
  • PowerBooster builds up to 120 tons of clamping force (secure holding of thick sheets, perfect hemming)
  • Encapsulated spindle drive in oil bath (low maintenance)
  • Servo-regulated motors right and left (ball screws)
  • Programmable clamping position (hemming)
  • Programmable opening height (fast operation)

Revolutionary folding beam design with intelligent crowning system

The folding beam is a true power component of this machine.

Its extremely rigid design allows only very low deflection. The intelligent crowning system automatically optimizes the folding beam and automatically compensates for deflections caused by the bending forces.

This enables the MEGAbend to achieve straight bends with thin or thick sheets, all material types, and long or short flanges when bending in the centre of the machine or on the side.

Fast movements ensure high productivity. Automatic adjustment to sheet thickness and bending radius increases productivity and flexibility when bending small batches.

  • Minimal deflection of the folding beam
  • Straight bends due to the intelligent crowning system
  • A folding beam can be used as a stop for inclined parts
  • No setting times due to automatic adjustment to thickness and bending radius
  • No downtime for material change
  • Fast movement means short cycle times
  • SpeedOptimizer increases speed by releasing the part when the folding beam moves to its home position
  • Automatic clamping of segmented folding beam tools
  • Gentle forming of coated materials
  • Servo motors and absolute encoders: fast working, no calibration
