Overview
The Ursviken EK 320 is a mid-range hydraulic CNC press brake offering 3,200 kN (320 tonnes) of bending force, positioned within Ursviken's EK series for high-force fabrication applications. Designed for the bending of thick plate and structural profiles, the EK 320 brings substantial tonnage capacity to shops that regularly process heavy-gauge steel, aluminium plate, and stainless steel sections. The rigid fabricated frame and oversized hydraulic cylinders ensure consistent force delivery without frame fatigue over long production runs.
Ursviken's EK series machines are characterised by their deep throat depth and generous open height, enabling operators to work with tall tooling configurations and box-bending setups that would be impossible on lighter machines. The EK 320 is frequently specified for pressure vessel component forming, heavy structural fabrication, and the production of large formed brackets and flanges used in the energy and construction sectors.
The machine is equipped with a modern multi-axis CNC back gauge and Ursviken's XPERT control system, which provides graphical bend sequencing, automatic tonnage calculation, and tool collision detection. The control interfaces with standard offline programming software, allowing complex job setups to be prepared away from the machine floor. Hydraulic crowning is standard on the EK 320 to manage the significant deflection forces involved at maximum capacity.
Safety systems on the EK 320 meet current European machinery directives, including laser-based front safety guarding, emergency stop circuits, and a safety-rated PLC. The machine's heavy construction means installation typically requires a reinforced floor and overhead crane access, but its durability and low cost per bend over its service life make it a sound long-term capital investment for heavy fabrication operations.

Frequently Asked Questions
01
The EK 320's 320-tonne capacity allows bending of mild steel plate up to approximately 25–30 mm thick depending on working length and bend radius. Stainless steel and high-strength steel require derating; the machine's CNC automatically calculates required tonnage and advises the operator if a setup exceeds safe limits.
02
Yes. The EK 320's combination of deep throat depth (550 mm) and high open height (700 mm) makes it well suited for box bending with intermediate tooling configurations. Ursviken offers a range of swan-neck and narrow punches for the EK series to facilitate deep box and channel forming.
03
Due to the machine's approximate 35,000 kg weight, a reinforced concrete floor is typically required. Ursviken provides foundation drawings as part of the installation package, and customers should consult a structural engineer to verify local floor load capacity before delivery. Overhead crane access is also recommended for tooling installation and maintenance.
