Overview
The Ursviken Kiber 3 4100/175 is a large-format hydraulic CNC press brake offering 4,100 mm of working length and 1,750 kN (175 tonnes) of bending force. Designed for production environments that regularly process wide sheet metal parts, the Kiber 3 combines a stiff welded-steel machine body with precision-ground guides to maintain angular accuracy across the full bed length. This model targets industries including energy, transportation, agricultural equipment, and industrial enclosure manufacturing where large formed panels are common.
The Kiber 3 designation reflects Ursviken's third-generation Kiber architecture, which introduced an updated CNC interface, improved hydraulic circuit efficiency, and a refined back gauge design. The standard five-axis back gauge covers common part geometries while optional extensions allow the system to handle deep or complex parts with multiple reference points. Delem DA-66T or equivalent touchscreen control provides offline 3D programming and tool library management, reducing setup time on repeat jobs.
Hydraulic synchronisation is managed via servo-proportional valves on both cylinders, ensuring parallel beam travel under asymmetric loading. The active crowning system compensates for frame and beam deflection, critical when bending 4-metre panels to tight angular tolerances. Safety is addressed through a comprehensive light curtain system and an integrated Safety PLC conforming to current EN standards.
The Kiber 3 4100/175 is a practical choice for fabricators moving up from medium-capacity machines who need to tackle larger panels without investing in specialist heavy-plate equipment. Its combination of working length, tonnage, and modern control capability positions it as a versatile production workhorse for contract fabrication and OEM part production.

Frequently Asked Questions
01
The Kiber 3 introduced an updated hydraulic circuit for improved energy efficiency, a refined servo-proportional synchronisation system for better beam parallelism under asymmetric loads, and a modern touchscreen CNC interface. Earlier generations used older proportional valve technology and less capable controls.
02
Yes. The standard 5-axis back gauge can be upgraded with additional Z-axis extensions and programmable fingers to handle complex parts with multiple bends or deep flange geometries. Ursviken offers modular back gauge expansions that are specified at the time of order or retrofitted later.
03
The active crowning system uses hydraulic cylinders integrated into the lower beam (bed) to introduce a controlled upward bow that counteracts the natural deflection of the machine frame under bending load. The CNC calculates the required crown based on the tooling setup and material parameters, automatically adjusting for each program step.
