Overview
The Prima Power PB series is a range of synchronised hydraulic press brakes designed to complement Prima Power's laser cutting, punching, and panel bending systems within a unified sheet metal production environment. Available in capacities from 40 to 320 tonnes and working lengths from 1,250 to 4,100 mm, the PB series covers the full spectrum of general fabrication bending requirements from light-gauge precision work to medium-heavy structural bending, using a consistent CNC platform and tooling system across the range.
The PB hydraulic press brake uses electro-hydraulic synchronisation with proportional valve control to deliver smooth, precise ram descent and Y1/Y2 cylinder positioning accuracy of ±0.01 mm. The frame is a monoblock welded steel construction with stress-relieving after fabrication, ensuring the rigidity needed for consistent angle repeatability across the working length. Automatic hydraulic crowning is available on wider models to compensate for bed deflection on long bends, maintaining parallel tooling contact across the full die width.
Prima Power equips the PB series with its own CNC control platform, which shares the same interface language and programming environment as the EB Bending panel bender and other Prima Power machines — simplifying operator cross-training in mixed-machine environments. The control supports 3D graphical programming, offline program import from Prima Power's CAD/CAM software, and DNC connectivity for network integration. A motorised multi-axis back-gauge is standard, with options for six-axis configurations on complex part families.
The PB series is particularly well-positioned for fabricators already using Prima Power laser cutting or punching systems who wish to standardise on a single machine brand and software ecosystem across their shop floor. The integration between Prima Power systems — shared part databases, unified programming software, and compatible automation interfaces — reduces the friction of managing a multi-brand mixed fleet and provides a clear upgrade path to FMS-level automation as production volumes grow.

Strengths & Limitations
Strengths
- Unified CNC platform shared with Prima Power's EB Bending and other machines simplifies operator training and fleet management in mixed Prima Power environments
- Wide capacity range from 40 to 320 tonnes covers everything from precision light-gauge bending to medium-heavy structural work in a single consistent product line
- Proportional valve hydraulic synchronisation delivers smooth, precise ram control with ±0.01 mm Y-axis positioning accuracy
- Seamless integration with Prima Power CAD/CAM software and FMS automation systems provides a clear upgrade path to full production line automation
- Automatic crowning on wide models ensures angle consistency across the full working length without manual shimming or operator intervention
Limitations
- As a hydraulic press brake, the PB series requires ongoing fluid and filter maintenance that servo-electric competitors in the same tonnage class avoid
- Prima Power's press brake market position is secondary to its laser cutting and punching strengths; competitors such as LVD, Trumpf, and Bystronic have deeper press brake application expertise
- The PB series premium over Turkish or Asian hydraulic press brakes of equivalent nominal specifications requires justification through the software ecosystem and integration benefits

Frequently Asked Questions
01
Prima Power offers an optional laser angle measurement system for the PB series that provides real-time angle correction similar in function to LVD's Easy-Form. This option is not standard on all configurations and should be specified at time of order. It is particularly recommended for shops bending high-variability material batches or working to tight angular tolerances.
02
Yes. The PB series is designed with FMS integration in mind. The machine includes the necessary I/O interface and CNC connectivity to link with Prima Power's FMS software for automated loading, scheduling, and production tracking. This makes the PB a compatible component in a PSBB (Punching, Shearing, Buffering, Bending) or laser-bending cell if the customer's production volume justifies automation.
03
The PB series represents Prima Power's current-generation hydraulic press brake platform with updated CNC control, proportional valve hydraulic system, and integration capabilities aligned with Prima Power's modern FMS and CAD/CAM ecosystem. The older P series used legacy CNC platforms that are less compatible with Prima Power's current software environment.
04
Prima Power supplies a range of standard precision-ground tooling compatible with the PB series' Wila-style automatic clamping system. The tooling range covers standard V-dies and punches for general fabrication plus specialised tools for specific applications. Third-party Wila-compatible tooling from Rolleri, Wilson Tool, and similar suppliers is also compatible.
05
Prima Power supports the PB series through its regional sales and service organisations in Europe, North America, and Asia-Pacific. Remote diagnostics are available through the machine's CNC connectivity, and Prima Power's applications engineering team can assist with programming, tooling selection, and process development for new part families. Spare parts availability is supported through Prima Power's global distribution network.
