Measuring the bend angle

Springback is a phenomenon that appears when bending any type of material under any type of condition. To get a precise bend, an angle measuring system is necessary for a perfect result without the need to perform preliminary tests or corrections.

GPS4 controls and adjust the angle during the bending process.

The heart of the system is the double-fork sensor establishing 4 contact points on the material: this detects the bending angle and sends the data to the press brake.

A Good First Win!

It is user-friendly because it does not require the input of thickness, length, type of material or bending force.

It eliminates the need to perform sample tests and only requires to set the bending angle.

Material characteristics have no impact on the system, because the angle is measured and dynamically compared to the target value.

With GPS4 you can work with very short minimum flanges, even equal to the minimum flange length allowed by the die.

You can work with pieces with many reverse bends, with no problems due to tolerances and error accumulation.

Surface gloss has no impact on the measurement.


  • Can work with flanges that do not extend beyond the width of the V-die
  • Maximum precision and repeatability without manual correction
  • Angle measurement is real, not theoretical
  • The system enables free space around the work area
  • It is possible to use up to four working stations
  • Available for most commercially available dies
