Description
Bernardo Hydraulic Press Brake AKPL 4000 x 125
The AKPL 4000 x 125 hydraulic press brake is designed for precise and uniform bends even on large sheet metal. With a bending force of 125 tons and a working length of 4000 mm, it is the choice for metalworking shops and workshops that require high performance. The manual crowning system, supplied as standard, compensates for deformations during processing, ensuring perfectly linear bends along the entire working length. The stress-free steel frame, synchronized cylinders, and ball screw backgauge guarantee stability and precision. The NC E21S numerical control makes operation simple and intuitive, while the quick tool change system minimizes setup times.

Frequently Asked Questions
How is the required bending force calculated?
Basic formula: F (kN) = (8 × thickness² × strength × length) / V-opening. For S235 steel (400 N/mm²) with V = 8× thickness: F ≈ 50 kN/m for every mm of thickness. Example: 2 mm over 2,000 mm → approx. 200 kN (20T). The AKPL should be chosen with a nominal force at least 20% higher than the calculated force. For different materials or complex geometries, contact Krollit for verification.
What is the maximum thickness for stainless steel with the AKPL?
The nominal capacity refers to S235 steel (400 N/mm²). For AISI 304 stainless steel (620 N/mm²), the capacity is reduced by 35–40%. For 5052 aluminum (195 N/mm²), it increases by 50%. Verify with Krollit for specific materials.
Are punches and dies interchangeable with those of other manufacturers?
AKPL press brakes use standard European punch holders (Wila/Wilson tooling). Compatibility with tools from other manufacturers must be verified on a case-by-case basis — it is preferable to use original Bernardo punches and dies to ensure correct clamping forces and safety. Contact Krollit for the availability of specific tools.
Is the backgauge motorized or manual?
It depends on the version. Basic AKPL models have a manual backgauge with screw adjustment. Versions with integrated NC have a motorized backgauge automatically positioned by the machine. Verify in the technical table of the specific model.
Are spare parts and assistance available?
Original Bernardo spare parts available with 3–5 business days shipping. Customer service in Italian available.
