How to choose a press brake - part 3

Energy efficiency, front supports, angle control

In this part we focus on energy efficiency, various types of front supporting arms and sheet followers, and angle control systems.

7 – Energy efficiency



It turns off the motor after a specific idle time.



Thanks to the inverter motor drive, it is possible to continuously vary the motor speed, adapting it to the bending cycle. Advantages are reduced energy consumption, less oil stress, less pump wear, less noise, increased speed and more flexibility.


It includes the Gasparini Adaptive Crowning Plus system with a standalone hydraulic circuit. It allows to use smaller motors and to reduce crowning reaction times.

Are you looking for a press brake that guarantees energy savings without compromising on the output? Choose one of Gasparini eco-friendly configurations: less consumption, more speed.

8 Front supporting arms and sheet followers



Best suggestion if your production does not require to move front supports and to change die height much often. Quick fastening system allows repositioning along the entire length.

Sliding Front Supports Plus

Front support arms, equipped with ball transfers, are attached to a linear guide and slide along the bench. It has a manual vertical adjustable axis with linear guide and precision screw to suit the die height.

Sheet followers

When you bend very big and thin sheets, it’s important to properly support the blanks in order to avoid reverse bending, due to the sheet own weight. With RPG back gauges, sheet followers can be installed also on the interior side of the machine.

9 Angle control systems


Mitutoyo Wireless Protractor

It’s a digital manual protractor wirelessly connected to the CNC. The CNC reads the resulting angle and automatically applies the required corrections.



GPS4 is the bend angle control


GPS4 controls and adjusts the angle during the entire bending cycle. A double-fork sensor, directly touching the material, detects the bending angle on both sides of the sheet. The CNC varies the ram position in real time to correct for springback and thickness variability.


LaserCheck relies upon two pairs of lasers and cameras to measure the sheet inclination.
