Salvagnini B3 Compact

The Salvagnini B3 Compact is a compact-format servo-electric panel bender designed for sheet metal fabricators that require the core benefits of Salvagnini's autonomous bending technology — tooling-free operation, rapid job changeover, and first-part-correct forming — in a machine footprint sized for smaller production floors, job shop environments, and operations that cannot accommodate the full-size B3 panel bender platform. The B3 Compact delivers the same programmable universal blade principle as the standard B3, scaled to a shorter maximum panel length and reduced drive power rating appropriate for lighter gauge sheet metal applications.

The compact form factor does not come at the cost of technological sophistication. The B3 Compact incorporates Salvagnini's MAC 3.0 adaptive control system, the same material measurement and springback compensation technology found in Salvagnini's full-production FMS platforms. MAC 3.0 probes each incoming sheet to measure actual thickness and determines the mechanical properties required for accurate bend angle calculation, then adjusts blade stroke depth automatically to compensate for material springback. The result is first-part-correct bending from the first piece of each job, eliminating the trial bends that consume machine time and raw material during setup on conventional press brakes.

The universal blade system on the B3 Compact adjusts its working length and working position automatically for each bend in the programmed sequence. There are no punch-and-die tooling sets to select, install, or align — the machine's tool library consists of the programmable blade system itself, which handles flanges, return flanges, hems, closed box profiles, and complex multi-bend sequences without mechanical intervention between bends. For high-mix production environments where jobs change frequently throughout the shift, this approach eliminates the per-job tooling setup cost that is the primary economic obstacle to short-run press brake production.

The B3 Compact is programmed using Salvagnini's SV software, which imports DXF or STEP flat patterns directly and automatically generates bend sequences, blade configurations, and cycle time estimates. Programs are stored in the machine library and recalled instantly for repeat jobs, making changeover effectively instantaneous for known parts. The CNC operator interface guides the operator through material selection, blank loading, and first-piece verification with a graphical step-by-step workflow that supports quick training of new operators.

Salvagnini targets the B3 Compact at job shops, precision sheet metal subcontractors, and OEM in-house fabrication departments that produce a high variety of enclosure panels, brackets, control housings, electrical boxes, and HVAC components in mild steel, stainless, and aluminum. The machine's all-electric drive eliminates hydraulic oil and the associated maintenance, provides quiet operation relative to hydraulic systems, and reduces energy consumption versus conventional hydraulic press brakes. Salvagnini supports the B3 Compact with its European and North American service network and a comprehensive SV software training program.
