Bernardo Folding Machine SB 305 S
The Bernardo SB 305 S manual bending machine is a compact and robust machine, designed for small bending jobs on sheet metal up to 305 mm in length and 1.0 mm in thickness (400 N/mm²). Suitable for craft workshops, maintenance workshops, and vocational schools, it allows for precise and reliable bending in a simple way. The ergonomic bracket handle enables quick and comfortable bending, while the stable structure guarantees strength and long durability. With a maximum bending angle of 135°, it is suitable for standard applications and small-scale operations. Thanks to its compact dimensions and low weight, the SB 305 S is easily transportable and is the choice for those looking for a practical, economical, and functional bending machine.

Frequently Asked Questions
What is the difference between the SB series and the TB series in the Bernardo bending machine range?
The SB series (like this SB 305) has cutting rails integrated into the structure: this allows you to cut the sheet metal to the desired size and bend it in the same position without moving the piece. The TB series, on the other hand, has a segmented upper blade (without cutting rails) — its superior strength and interchangeable segments make it suitable for complex profiles (boxes, U-shaped edges, double folds) and thicker sheet metal. SB: cuts and bends thin sheet metal. TB: bends with a segmented blade for complex shapes.
Does the SB 305 cut and bend in the same position?
Yes — this is the main advantage of the SB series. The integrated cutting rails allow you to cut the sheet exactly to the desired width and then bend it immediately, keeping the piece in position. This eliminates the positioning errors typical of transferring between a separate cutting machine and bending machine, resulting in significant time savings in production.
What is the maximum thickness for aluminum and stainless steel with the SB 305?
The nominal capacity of 1.0 mm refers to S235 steel (400 N/mm²). For aluminum (160–200 N/mm²), the capacity increases by 30–50% — approximately 1.4 mm. For AISI 304 stainless steel (600 N/mm²), the capacity is reduced by 30–40% — approximately 0.7 mm. For copper: similar behavior to aluminum.
How do you create a U-bend or a box with the SB 305?
The SB 305 is from the SB series — without a segmented blade, deep U-bends and boxes with high edges are not easily achievable (the high edge of the sheet metal interferes with the machine's structure during bending). For frequent production of U-profiles and boxes, consider the TB series with a segmented blade that allows for the removal of central segments to free up the necessary space.
Do the cutting blades wear out and need to be replaced?
Yes — the integrated cutting blades wear out after intensive use. Original Bernardo replacement blades are available with 3–5 working day shipping. Signs of wear: cut is no longer clean, need for excessive force, burrs on the cut edge.
