Bernardo Hydraulic Press Brake AKPL 3200 x 160

Bernardo AKPL 3200 x 160 hydraulic press brake

The AKPL 3200 x 160 hydraulic press brake is designed to meet the needs of workshops and metal fabrication shops that require a powerful and versatile machine for processing large sheet metal. With a bending force of 160 tons and a working length of 3200 mm, it ensures high performance and precise results even with significant thicknesses. The manual crowning system, supplied as standard, ensures perfectly uniform bends along the entire working length. Thanks to the synchronized cylinders, the robust steel frame, and the backgauge with ball screw, the machine offers stability, reliability, and precision. The NC E21S control makes operation simple and intuitive, while the quick tool change system reduces 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 each 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 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. Check the technical table of the specific model.

Are spare parts and assistance available?
