Back Gauge Systems
Every Schiavi press brake is fitted with a back gauge built by Schiavi. Five systems cover the range, from a motorized X–R gauge for straightforward work to an eight-axis tower gauge for complex, multi-stage sequences.
The five systems
- MPS1 – the robust, efficient entry-level solution. A motorized X axis for precise depth positioning, ensuring consistent flange sizes and fast, repeatable part referencing for high-volume standard bending.
- MPS3 – exceptional value and performance: highly accurate two-axis positioning with motorized X (depth) and R (height) for quick, precise referencing of standard and complex parts. The standard-to-mid-range gauge.
- MPS-CZ – a specialized gauge with a double motor on the X axis. The two motors shift the rear beam independently, so the machine can perform conical bends. Increased versatility for specific, complex bending operations.
- MPS-H – unmatched speed and precision for high-performance press brakes. A large 27.56 in stroke and 39.37 in reference distance, driven by ball screws on sturdy guides, for ultra-fast, repeatable positioning of complex, large-scale parts.
- MPS8 – comprehensive control with the eight-axis tower gauge. Independent positioning of two towers across the working width handles complex parts and unique tooling configurations for demanding, multi-stage sequences.
Axis naming. X – depth (distance from the die center). R – height of the gauge fingers. Z – position along the bed. Numbered axes (X1, X2 …) move independently, so the beam can be angled for conical bends or two towers can be positioned separately.

Options for every family
- Real-time bending angle measurement – Schiavi's measuring device reads the actual angle during the bend and lets Athena correct for springback on the first part, reducing scrap and setup time.
- Front sheet-follower supports – powered supports that carry large or heavy blanks through the bend, managed by the same Task software as the back gauge. (Static front supports are also available.)
- Hydraulic or hybrid drive – hybrid drive delivers up to 40% energy savings, up to 30% higher speed and –10 dB noise; available across the HFBx and HFBs ranges, on the BSTs 50.12 and 50.20 and on LineAr 130.30–400.60.
- Automation – TK Mini, Flex and Mega robotic bending cells programmed offline in A.R.S.
