Hydraulic Press Brake & Sheet Metal Bending Machines

For an initial capacity check, use the press brake tonnage calculator to estimate air-bending force from tensile strength, thickness, active bend length and V-die opening.

Every machine is built to CE safety requirements and ships with a 24-month warranty, English interface and manuals, plus remote troubleshooting and commissioning guidance — the same package we have delivered to metal fabrication customers in more than 70 countries.

Metal fabricators also search for these bending machines as a steel sheet bending machine or steel metal bending machine when comparing NC, CNC, hydraulic and electric press brake configurations.

Which press brake machine fits a given job is a thickness × length problem first, then an axes and controller problem. The eight BEIGEMA units in this category are NC torsion-bar frames, CNC hydraulic frames, a pure-electric range, and a tandem pair range. Size the kN, then drop any series whose length, throat, opening, or axis count cannot take the part.

Worked loads use the air-bend formula on the press brake tonnage calculator: F(kN/m) ≈ 650 × t² / V, with 650 set for 450 MPa mild steel and V ≈ 8 × thickness. Thickness enters as t². Halve V and the force doubles. How to choose a press brake is the longer walkthrough; CNC vs NC press brake is the control split.

All three examples assume 450 MPa mild steel, air bending, and V = 8 × t. Stainless and high-strength grades need a material factor on top of 650. Put tensile and V into the press brake tonnage calculator rather than copying these kN values.

For 2 mm × 2 m at V = 16 mm, F = 650 × 2² / 16 = 650 × 4 / 16 = 162.5 kN/m, and 162.5 × 2 = 325 kN. The smallest pure electric press brake is rated 350 kN (range 350-1000 kN, length 1350-3960 mm), so the 35T class covers 325 kN. A WC67K with E21 starts at 400 kN and a 2200 mm table, which also covers a 2 m blank. Skip tandem: listed bending length starts at 4000 mm.

For 6 mm × 3 m at V = 48 mm, F = 650 × 6² / 48 = 650 × 36 / 48 = 487.5 kN/m, and 487.5 × 3 = 1462.5 kN. Pure electric tops out at 1000 kN, so you’ll need a WC67K or MB8 frame above 1462.5 kN. If the die V is 24 mm rather than 48 mm, force doubles to 2925 kN.

For 12 mm × 4 m at V = 96 mm, F = 650 × 12² / 96 = 650 × 144 / 96 = 975 kN/m, and 975 × 4 = 3900 kN. That is inside WC67K up to 6000 kN and MB8 up to 12000 kN, and outside pure electric. A tandem listing of 2×250T/4000 is 2500 kN per side, so 3900 kN is above one 250T ram .

Throat is the other hard stop after kN: WC67K and pure electric 200-400 mm, MB8 350-600 mm, tandem 410-500 mm, so a return flange deeper than 400 mm is already outside WC67K and electric. Column distance matters if a formed U must pass between the side frames: electric 900-2700 mm, MB8 1900-8000 mm, tandem 2700-5100 mm.

The three WC67K pages are the torsion-bar NC range (30 models, 40/2200 to 600/6000). Use that hydraulic press brake for stored single-angle work; do not buy it when throat must exceed 400 mm or the table must exceed 7000 mm. E21 is the lowest-cost control for simple, repeatable work; TP10S and E310P are the two 2-axis servo NC options on the same frame. Crowning is not in these spec rows, and 0.05 mm rear-gauge precision is published only on MB8.

The MB8 with DA-53Tx is the entry CNC press brake on 4+1 axes with touch operation, on the same 21-model frame as the other MB8 pages. Use 4+1 when up to four back-gauge axes cover the flanges. Do not pick it when the part needs more axes than that. Rear-gauge precision is listed at 0.05 mm.

DA-66S and DA-69S keep that MB8 envelope and 6-8 axes. DA-66S is 2D graphical programming with automatic sequencing and collision detection; DA-69S adds full 3D part programming and simulation (see the press brake controller comparison). Do you actually need full 3D part programming and simulation, or does 2D graphical programming with collision detection already run the cell? Skip both 6-8-axis pages if an NC X/Y controller already stores the bends, and skip DA-66S if simulation is a written requirement.

The pure electric press brake is six servo-driven models from 35T 1350 to 100T 3200 (350-1000 kN, 1350-3960 mm, 1.1-2.7 kW). It’s the low-kW bending machine for loads at or under 1000 kN. Do not use it for the 6 mm × 3 m example (1462.5 kN), or for beds longer than 3960 mm. The controller name is not on the spec row.

The tandem press brake is 14 synchronized-pair models from 2×250T/4000 to 2×500T/6000: listed length 4000-6000 mm, throat 410-500 mm, mass 130-160 t. Use it for long plate that needs two frames. Do not park a 2 m shop part on a 130 t line, and do not treat a 2×250T side (2500 kN) as enough for 3900 kN . The controller type is not listed.

Send six items with the RFQ. Material (grade and tensile, not just “steel”). Thickness range, minimum and maximum. Longest workpiece in mm, not the average blank.

Maximum workpiece weight, because sheet followers and back-gauge fingers are a separate choice on the press brake back gauge page. Bend angle and springback requirement; the 650 formula is air bend, not bottoming. How many back-gauge axes you will program, which also sets the tooling package.

If you need a published ram or angle repeatability, the MB8 row only lists rear-gauge precision at 0.05 mm. Name the press brake machine after those six inputs.

Yes. 325 kN at V = 16 mm is below the pure-electric 350 kN floor and the WC67K 400 kN floor, so either series in its smallest listed model covers the load. A 2 m blank fits both beds; tandem listed length starts at 4000 mm, so skip it.

6 mm × 3 m at V = 48 mm is 1462.5 kN, above the pure-electric 1000 kN cap, so specify WC67K or MB8 above that kN. If the side flange is deeper than 400 mm, drop WC67K and electric (MB8 throat to 600 mm, tandem to 500 mm).

WC67K is torsion-bar NC with E21, TP10S or E310P controls. MB8 is the CNC press brake family, 4+1 with DA-53Tx (touch operation) or 6-8 axes with DA-66S / DA-69S. If the work is simple, repeatable bending, WC67K matches; graphical programming, 0.05 mm rear gauge, throat to 600 mm, or length to 10000 mm put you on MB8.

No. DA-53Tx, DA-66S, and DA-69S share 630-12000 kN and 1300-10000 mm. The split is axes and programming: 4+1 with touch operation, 6-8 with 2D graphical programming and collision detection, 6-8 with full 3D programming and simulation. Pick the controller from the program you will run, not from the kN row.

MB8 bending length is listed to 10000 mm on one frame; tandem is listed 4000-6000 mm as a synchronized pair at 2×250T to 2×500T. Use tandem when the RFQ is two frames for long plate; use a long MB8 when one bed to 10000 mm and 6-8-axis CNC is the requirement. Tandem opening is 620-670 mm and the listed mass is 130-160 t.

Tonnage is a thickness-and-length problem before it is a controller problem. BEIGEMA's press brake range runs from 40 tons/2200 mm (WC67K) up to 1200 tons (MB8), with tandem configurations to 2×500 tons for plates longer than one bed. Match the bending length, throat depth, open height and axis count to the part first, then confirm the tonnage sits inside the published band for that frame, not just the headline capacity.

Uneven bend angle usually comes from ram deflection, back-gauge alignment or die wear rather than the controller. On long parts, crowning compensation is the key variable: BEIGEMA's CNC frames pair with DELEM DA-53T, DA-66S and DA-69S controllers offering up to 8+1 axes, which correct for deflection across the bend length. Check tooling squareness and V-die wear first, then confirm crowning is engaged for the material thickness and part length before adjusting the program.

Yes. The CNC and NC press brake range covers 40 tons/2200 mm up to 500 tons/6000 mm, plus tandem pairs to 2×500 tons for plates beyond a single bed length. Controller options span E21, TP10S and E310P to DELEM DA-53T, DA-66S and DA-69S.
