Description
Bernardo AKPL 1600 x 40 Hydraulic Press Brake
The AKPL 1600 x 40 hydraulic press brake is designed for high precision and reliability in metalworking. With a bending force of 40 tons and a working length of 1600 mm, it is the choice for workshops that need a compact yet powerful machine. The synchronized dual-cylinder system and the robust high-strength steel frame ensure stability and long durability. The segmented upper tool with quick change reduces setup times, while the E21S NC control makes machine management simple and efficient.

Frequently Asked Questions
How to calculate the required bending force?
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 attachments (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 for the specific model.
Are spare parts and assistance available?
Original Bernardo spare parts available with 3–5 business days shipping. Customer support available in Italian.
