Who uses the AKPL 3200 x 100 and for what
The Bernardo AKPL 3200 x 100 is a hydraulic press brake with numerical control for industrial sheet metal bending up to 3.2 meters long with 100 tons of force. Synchronized cylinders ensure parallel descent of the upper beam: a decisive feature for uniform bends over the entire length, avoiding 'crooked' bends typical of manual bending machines over significant lengths. The backgauge with ball screw (0-600 mm stroke) and the NC E21S control allow for positioning repeatability of less than 0.1 mm, transforming the AKPL into a semi-automated production machine: the operator programs the bending sequence, and the machine correctly positions the sheet metal for each bend. The segmented upper tool with quick clamping and the lower tool with 9 V-openings cover the vast majority of standard bends without tool changes. In Krollit customers' workshops, it is chosen by industrial metal fabricators, steel structure construction workshops, industrial frame manufacturers, and sheet metal processing workshops that require precision and repeatability.
Its place in the Bernardo range
The AKPL 3200 x 100 is the entry-industrial hydraulic press brake in the Bernardo AKPL range. Above it, the range offers AKPL with higher tonnages (130, 160, 220 tons) and lengths up to 4 meters for heavy industrial applications. Below it (in terms of processing type) are the TBM 2020/3020 motorized bench folders for lighter production on sheet metal up to 1.5 mm. The difference between AKPL and TBM is in purpose: TBM bends thin sheet metal (max 1.5 mm) with a blade tool, AKPL bends thick sheet metal with a V-tool. The AKPL 3200 x 100 with 100 tons is sized for bending mild steel up to approximately 4-5 mm thick (actual capacity depends on the V-geometry used). For bending sheet metal over 5 mm thick or lengths over 3.2 meters, consider higher tonnage AKPLs.
Krollit logistics and support
Bernardo shipping in 5-9 working days (7 days to the South). At 6,700 kg, it requires a crane of adequate capacity and a suitably sized workshop access. Dimensions 3,650 × 2,080 × 2,300 mm: check ceiling height and flooring. A suitably sized reinforced concrete foundation is recommended. Original Bernardo tools, spare parts, and accessories are available from stock with 3-5 working day shipping. Italian customer support is available.
Who the AKPL 3200 x 100 is for
| Profile | Compatibility | Reason |
|---|---|---|
| Passionate hobbyist | Not suitable | Industrial machine weighing 6,700 kg with numerical control. Exclusively professional application. |
| Industrial metal fabricator | Recommended | 100 tons over 3,200 mm with NC E21S control covers most standard industrial bends. Backgauge with ball screw offers positioning repeatability below 0.1 mm. |
| Steel structure production | Recommended | Suitable for series production on medium sheet metal. Cylinder synchronization produces uniform bends over the entire working length. SDKELI safety system complies with industrial regulations. |
Not suitable for: processing sheet metal over 4-5 mm thick (consider AKPL with higher tonnage); pieces over 3,200 mm long; bending thin sheet metal (under 1.5 mm) for which TBM bench folders are more suitable; high-volume automated series production with robotic manipulators (integrated CNC presses).

Frequently Asked Questions
What do 'synchronized cylinders' mean?
The two hydraulic cylinders (one per upright) move in strict parallel thanks to a mechanical or electronic synchronization system. The upper beam descends straight, avoiding inclined bends along the length.
On bending machines without synchronization, the two cylinders can move at slightly different speeds, producing 'crooked' bends (tighter at one end than the other). Over significant lengths like 3.2 meters, this discrepancy is unacceptable for industrial production. Synchronization is a crucial design feature of professional press brakes, and Bernardo implements it as standard on the AKPL.
Can I bend thick sheet metal with the AKPL 3200 x 100?
The actual capacity depends on the V-geometry used. For mild steel with correctly sized V-dies, the machine typically bends 3-5 mm thick in single bends over the entire working length.
Bending force is not only a function of the press's tonnage: it also depends on the width of the V-die (wider V-die requires less force), the bent length, and the material's resistance. For thicker bends, it is recommended to consult the Bernardo bending tables (supplied with the machine) which indicate the actual capacity for each thickness-V-length-material combination. Regular processing over 5 mm thick requires a higher tonnage AKPL.
Is the NC E21S control easy to use?
Yes, it is an entry-industrial numerical control with an intuitive operator interface. It allows programming of bending sequences, program storage, and automatic sheet development calculation.
The NC E21S is an industry standard with a manageable learning curve: an experienced bending operator learns programming in 2-3 days of practice. Programming a complex bending sequence requires expertise in bending technique (correct order, sheet development calculation, V-die selection), expertise that belongs to the operator, not the control. For repetitive series production, the initial programming investment quickly pays off.
What kind of foundation does it require?
A reinforced concrete foundation sized for the machine's 6,700 kg weight. For precision work, a dedicated slab isolated from the rest of the floor is recommended.
The 100 tons of force during bending generate reactions that are discharged onto the foundation. A standard industrial floor of good quality is generally sufficient; for workshops with light or filled-in floors, dedicated consolidation is recommended. Krollit does not provide foundation laying services: involve a qualified installer for site preparation.
How much does it produce in one hour of standard bending?
For standard repetitive bends on medium-sized sheet metal with a single bend per piece, the typical output is 60-100 pieces per hour, considering piece and backgauge positioning. With multiple bends per piece, the output is proportionally reduced.
The machine cycle speed (90 mm/sec approach, 8 mm/sec bend, 90 mm/sec return) allows for rapid cycles. Actual output is limited by piece positioning: the backgauge with ball screw and NC control significantly speed up this aspect compared to manual bending machines. For automated production with feeding robots, dedicated industrial configurations are necessary.
