Advantage:
-
The frequency response (response frequency) is higher and can be as high as 200Hz.
-
It can continuously and proportionally control the pressure and flow of the hydraulic system, control the position, speed, and force, and reduce the impact of pressure changes.
-
Closed-loop control, signal feedback.
-
Original German imported products, longer service life.
Advantage:
-
>High dynamic for a higher productivity of the machine.
-
>Compliance with EU Directives.

Bending Follower Features
bend a very large, heavy and thin plate. The overhang generates a torque that makes the sheet bend around the die edge under its own weight, as we can see in the drawing. The sheet lifter helps to avoid this type of damage, supporting the plate during the entire bending cycle.
-
AP1 - AP2 CNC-controlled interpolated axes
-
Light solution, easy to move
-
Adjustable according to the size of the workpiece
-
Improved shop floor efficiency
-
Less physical strain and safety risks
-
Protection from counterbends and scratches
-
Bend as closed as 70°
-
R axis -30/+170 mm; maximum die opening 100 to 160 mm
-

Laser Check Angle Measurement System
The iMeasure Laser angle measurement system with Data-M Engineering for an accurate bend angle after only one bending operation.
The iMeasure are fully-automatic laser-assisted bend angle measurement systems for CNC press brakes. Irrespective of the properties or thickness of the material, the LaserCheck enables an exact determination of the bending angle with an accuracy of better than 0.1°. This represents precision which has never been available before.
-
A laser beam is projected on the sheet metal surface
-
The camera detects the laser beam
-
The angle between the beam and the camera axis determines the bend angle
-
Force reduction + calculation of the springback
-
Automatic angle correction
Front Sheet Follower Supports System
The hydraulic press brakes with Sheet supports follower system for bending long and thin sheets,It basically consists of a pair of sheet supports placed on the front of the machine at the height of the bending line (bottom tool). Supports are controlled by the CNC, following and supporting the sheet during the bending process.
-
Automatic bending follower supports
-
AP1 - AP2 CNC-controlled interpolated axes
