Bernardo Hydraulic Press Brake AKPL 3200 x 125

Bernardo AKPL 3200 x 125 Hydraulic Press Brake

The AKPL 3200 x 125 hydraulic press brake is designed for uniform, precise, and repeatable bends on large sheet metal. With a bending force of 125 tons and a working length of 3200 mm, it offers high performance and reliability even in the most demanding operations. The manual crowning system, supplied as standard, allows compensation for natural deformations and ensures perfectly linear bends. The robust, stress-free steel frame, synchronized cylinders, and backgauge with ball screw guarantee maximum stability and precision. The simple and intuitive NC E21S numerical control makes machine management quick and efficient, while the quick tool change system reduces setup times.

Frequently Asked Questions

How is the necessary 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 each mm of thickness. Example: 2 mm on 2,000 mm → approximately 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 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. Refer to the technical table for the specific model.

Are spare parts and assistance available?

Original Bernardo spare parts available with 3–5 working days shipping. Customer support in Italian available.
