Description
Bernardo Hydraulic Press Brake AKPL 4000 x 160
The AKPL 4000 x 160 hydraulic press brake is designed to meet the demands of fabricators and workshops that process large and thick sheet metal. With a bending force of 160 tons and a working length of 4000 mm, it ensures power, stability, and precision even in the most demanding operations. The manual crowning system, supplied as standard, compensates for structural deformations during bending, producing uniform results across the entire working length. The stress-free steel frame, synchronized cylinders, and backgauge with recirculating ball screw provide high precision and durability. The E21S NC control makes operation simple and efficient, while the quick tool change system significantly reduces setup times.

Frequently Asked Questions
How is the necessary bending force calculated?
Basic formula: F (kN) = (8 × thickness² × tensile strength × length) / V-opening. For S235 steel (400 N/mm²) with V = 8× thickness: F ≈ 50 kN/m for each mm of thickness. Example: 2 mm on 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 other manufacturers?
AKPL press brakes use standard European punch holders (Wila/Wilson tooling). Compatibility with tools from other manufacturers should 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. Refer to the technical table of the specific model.
Are spare parts and assistance available?
Original Bernardo spare parts available with 3–5 business day shipping. Italian customer support available.
