Bernardo HSB 3200 x 6 – Hydraulic plate shear for sheet metal up to 6 mm

Bernardo Hydraulic Shear HSB 3200 x 6

The Bernardo HSB 3200 x 6 hydraulic shear is a high-performance industrial machine, designed for efficient and safe cutting of sheet metal up to 3200 mm in length and 6 mm in thickness (400 N/mm²). The robust welded steel structure reduces torsion and vibration, consistently producing precise results. The integrated cutting line illumination with a shadow contour ensures maximum visibility, while the motorized CNC backgauge (20–600 mm) allows for accurate and repeatable operations. The low-angle cutting bar (1°50’) and front support arms facilitate working with even large panels. Safety is guaranteed by protective grids, photocells, and a foot pedal with an emergency stop. With a 7.5 kW motor, 14 hold-downs, and a weight of 6650 kg, the HSB 3200 x 6 is a reliable, robust professional shear, ideal for metal fabrication shops and workshops.

Frequently Asked Questions

Does this shear have integrated CNC control?

Yes. The HKS and HSB series Bernardo hydraulic shears are equipped with the ES21S CNC control as standard, which manages the automatic cutting cycle, backgauge programming, and diagnostics. The CNC panel allows for programming repeated cycles without manual intervention between cuts.

What is the maximum thickness for stainless steel?

The nominal thickness of 6 mm refers to S235 steel (400 N/mm²). For AISI 304 stainless steel (600 N/mm²), the capacity is reduced by 30–40% (approximately 3.9 mm). Please verify with Krollit for specific materials.

Are the blades reversible and how long do they last?

Yes. The blades have 4 reversible cutting edges. Their lifespan depends on the material cut and its thickness: on standard mild steel, the blades last for thousands of cuts before needing replacement. Original Bernardo blades are available with 3–5 business day shipping.

Is a special foundation required?

Large format hydraulic shears require an adequate industrial floor. For machines over 3,000 kg, consult a structural engineer. Coordinate with Krollit before ordering for complete installation specifications.

How much space is needed in the workshop?

Minimum clear space equal to the cutting length (3200 mm) in front of and behind the machine. For coil sheets, add the space for the uncoiler. Contact Krollit for complete machine dimensions.
