MRP tool compatibility
Existing tool applications from MRP (Meyer, Roth & Pastor) UB2, UB2B, UB3, UB3B, UB4 and UB4B machines are adapted and optimised for the BNC 4; UB2/3/4 cutting die sets are mounted using adapter sets.
Servo multi-slide
Bihler BNC 4
Servo multi-slide production system compatible with MRP tooling
300 1/min Stroke rate
200 kN Press force
31 kN NC unit force (max.)
40 mm Strip width
Ø 4 mm Wire diameter
ⓘ Manufacturer data (Bihler BNC 4 product page, BNC 4 brochure 07/23); the brochure gives stroke values separately for UB3/UB3B and UB4/UB4B tool layouts. Values may change and vary; not binding on Boztaş.
Why BNC 4?
Programmable NC units
Working stroke, position and motion profile are freely programmable over the entire operating range; the NCA units carry adapted mounting plates and a quick-change system for UB2/3/4 tools.
Process reliability
Integrated cooling and central lubrication on all units, software overload protection and absolute measuring system; process-related thermal effects are compensated.

Frequently asked questions
Which MRP tools can be transferred to the BNC 4?
Existing tool applications from MRP UB2, UB2B, UB3, UB3B, UB4 and UB4B machines are adapted and optimised for use on the BNC 4. UB2/3/4 cutting die sets are mounted with adapter sets, forming tools via adapted mounting plates on the NCA units.
What is the difference between the BNC 4 and the RM-NC?
Both run at up to 300 1/min with a 200 kN servo eccentric press. The BNC 4 is configured to the MRP standard (4 × 40 mm strip, NC units up to 31 kN); the RM-NC is the LEANTOOL Radial R60 platform for Bihler RM and FINZER tools (4 × 80 mm strip, 20 kN / 120 mm units, up to 14 axes).
Does the BNC 4 process both strip and wire?
Yes; the RZV 2.1 servo feed is designed for strip and wire material without retooling mechanical components, and material guides for different dimensions are changed quickly. Capacity is 4 × 40 mm strip and Ø 4 mm wire.
