Frequently Asked Questions
What is a notching machine and what is it used for?
A notching machine (or "corner notcher") cuts square corners in sheet metal to allow it to be bent at 90° without overlapping the material. This is fundamental for the production of boxes, trays, containers, and sheet metal profiles: without notching, the corner remains closed and the sheet metal does not bend correctly. Bernardo AK series machines cut 90° angles on sheet metal up to 3 mm thick, in sizes from 80 × 80 to 150 × 150 mm.
What is the difference between AK 80 F, AK 100, AK 125, and AK 150?
The number indicates the maximum size of the corner cut (side of the square): AK 80 F → 80 × 80 mm, AK 100 → 100 × 100 mm, AK 125 → 125 × 125 mm, AK 150 → 150 × 150 mm. The thickness capacity varies slightly between models (from 2.5 to 3.0 mm). The suffix F indicates a version with rapid feed. The choice depends on the maximum angle size to be cut.
Does the maximum thickness also apply to stainless steel and aluminum?
No. The nominal capacity refers to S235 steel (400 N/mm²). For AISI 304 stainless steel, it is reduced by 30–40%. For aluminum, it increases by 30–50%. Please check with Krollit for specific alloys.
Are the cutting blades replaceable?
Yes. The cutting blades wear out and are replaceable. Original Bernardo replacement blades are available with 3–5 business day shipping.
Is assistance available?
Original Bernardo spare parts available with 3–5 business day shipping. Customer support in Italian available.
