Bernardo HKS 3200 x 8 – CNC Hydraulic Shear for sheet metal up to 8 mm

Bernardo HKS 3200 x 8 Hydraulic Shear

The Bernardo HKS 3200 x 8 hydraulic shear is a high-performance industrial machine, ideal for efficient cutting of sheet metal up to 3200 mm in length and 8 mm in thickness (400 N/mm²). The linear movement of the cutting beam and the adjustable angle between 0.5° and 1.5° ensure optimal results, especially with thin sheets. The motorized CNC backgauge, adjustable from 20 to 600 mm, ensures high precision, while the continuous adjustment of the cutting length saves time for short workpieces. The robust welded steel structure reduces vibrations and torsion, while the cutting line illumination with shadow contour facilitates processing. Safety is guaranteed by photocells, protective grids, and a foot pedal with an emergency stop. With a 7.5 kW motor, 14 hold-downs, and speeds up to 30 strokes/min, the HKS 3200 x 8 is suitable for metalworking shops and workshops that require precision and productivity.

Frequently asked questions

Does this shear have integrated CNC control?

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

What is the maximum thickness for stainless steel?

The nominal thickness of 8 mm refers to S235 steel (400 N/mm²). For AISI 304 stainless steel (600 N/mm²), the capacity is reduced by 30–40% (approximately 5.2 mm). Please check with Krollit for specific materials.

Are the blades reversible and how long do they last?

Yes. The blades have 4 reversible cutting edges. The 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, please 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 space for the uncoiler. Contact Krollit for complete machine dimensions.
