How to choose a press brake – part 3

Energy Efficiency, Front Support, Angle Control
In this part, we focus on energy efficiency, various types of front support arms and plate followers, and angle control systems.

7 – Energy Efficiency

It turns off the motor after a certain idle time.

Thanks to the variable frequency motor drive, the motor speed can be varied continuously to adapt it to the bending cycle. The advantages are reduced energy consumption, reduced oil pressure, reduced pump wear, reduced noise, increased speed and greater flexibility.

It includes the Gasparini Adaptive Crowning Plus system with independent hydraulic circuits. It allows the use of smaller motors and reduces convex reaction times.

Are you looking for a press brake that guarantees energy savings without compromising output? Choose one of Gasparini’s eco-friendly configurations: consume less and go faster.

8 Front support arm and plate follower

This is the best advice if your production does not require moving front supports and changing mold height frequently. 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.

Table followers
When you bend large, thin plates, it is important to support the blank correctly to avoid reverse bending due to the plate’s own weight. With the RPG back stop, the sheet follower can also be mounted on the inside of the machine.

9 Angle Control System

Mitutoyo Wireless Protractor
It is a digital manual protractor that connects wirelessly to the CNC. The CNC reads the resulting angle and automatically applies the required corrections.


GPS4 controls and adjusts the angle during the entire bending cycle. Bifurcated sensors in direct contact with the material detect the bending angle on both sides of the sheet. The CNC controller changes the ram position in real time to correct for springback and thickness variations.


LaserCheck relies on two pairs of lasers and a camera to measure the inclination of the sheet.
