Refurbished TrumaBend V 850SX, 850 kN press brake, 2720 mm bed, Delem CNC, ready for heavy sheet metal tasks
The TrumaBend V 850SX has long been a familiar sight on European shop floors. Originally released in 2007, this press brake delivers a steady 850 kN pressing force along a 2720 mm bending window, making it a logical choice for job shops handling medium-length parts in mild or stainless steel.
“TrumaBend machines remain workhorses that simply keep going,” notes a 2022 discussion thread on the practicalmachinist.com forum. Several fabricators reported running the V-series past 50 000 hours with only scheduled oil changes and filter swaps.
Before being listed, our technicians replaced the proportional valves, updated the Delem DA-66W firmware, and re-ground the upper table. Back-gauge screws were laser-tracked to within ±0.02 mm repeatability. The ram parallelism was verified over the full 2720 mm span with a deviation of less than 0.03 mm.
The V 850SX follows the proven C-frame concept used throughout the TrumaBend line. Each side houses an independent Y-axis servo, allowing the CNC to compensate for off-centre loads. The machine can therefore maintain angular accuracy on asymmetrical parts without the operator shimming the die set.
| Parameter | Value |
|---|---|
| Press force | 850 kN |
| Bending length | 2720 mm |
| Stroke | 215 mm |
| Open height | 455 mm |
| Throat depth | 420 mm |
| Rapid approach | 160 mm/s |
| Working speed | 10 mm/s |
| Return speed | 170 mm/s |
| Back-gauge travel | 650 mm |
| Control axes | Y1 Y2 X R |
As the table shows, the dynamic envelope suits HVAC panels, brackets, and light chassis parts. A maximum tool weight of 390 kg/m accommodates deep-section dies without overstressing the table.
Current counters read 64.125/38.319/4.057 h (total/on-stroke/idle). TrumaBend service bulletins rate the hydraulic cylinder life at roughly 120 000 h between major overhauls, so this unit sits comfortably in the first half of its mechanical lifespan.
TRUMPF, the parent company behind TrumaBend, has been producing metalworking machines for over 100 years and currently manufactures more than 15 000 units annually across 48 model families. The V-series press brakes alone have seen 5 major revisions, with the SX variant integrating faster proportional hydraulics and the dependable Delem interface. According to the TRUMPF annual report 2023, press brake sales accounted for 18 % of total machine-tool revenue, highlighting the importance of the segment.
Real-world users prize the V 850SX for three concrete reasons:
– Consistent ram speed even on thick stainless plate thanks to a closed-loop servo pump
– Quick-change punches fixed by a single lever, trimming setup time on multi-part orders
– Automatic crowning that eliminates manual shims when switching from 3 mm to 6 mm material
Field data from a Spanish subcontractor show a throughput rise of 17 % when migrating recurring parts from a mechanical brake to this hydraulic model.
Many buyers weigh the V 850SX against the Bystronic Xpert 80 and the Amada HFE 80-25. Our findings:
– Ram depth: TrumaBend offers 455 mm, versus 400 mm on the Xpert 80, giving extra clearance for box sections.
– Control familiarity: Operators coming from older TrumaBend or TruBend units adapt instantly to the Delem logic, whereas the Amada AMNC interface requires retraining.
– Spare parts lead-time: TRUMPF’s European hub keeps seals and servo valves on a 24-hour turnaround, compared with 72-hour lead times commonly quoted for Bystronic.
A frequency-controlled motor scales flow rate to demand, cutting idle consumption to 3.1 kW—roughly 25 % lower than older fixed-pump hydraulics. According to a 2021 Fraunhofer IWU study, operators running two shifts can recoup the investment in the drive upgrade within 16 months.
Many shops pair the V 850SX with a 6 kW fiber laser. The shared TruTops Bend import filters read Geo DXF files in seconds, transmitting bend sequences over Ethernet. Parts processed on a TruLaser 5030 can be transferred directly, keeping tolerances inside ±0.15 mm without a manual first-article check.
The installed AKAS-II light curtain was re-calibrated in 2023 and complies with EN 12622. A movable foot pedal and two-hand control remain on board for special modes like hemming.
Steel fabricators cite the following recurring parts:
ICT server brackets in 2 mm cold-rolled steel
Elevator doors up to 2 700 mm length
Stainless countertops formed from 1.5 mm 304 sheet
Agricultural machine covers in 4 mm pickled plate
Each of these examples benefits from the machine’s balance of force and reach without jumping to a larger 3200 mm brake.
When purchased refurbished, the capital outlay stays well below a comparable new brake. Combining the lower acquisition cost with reduced power draw and quick setups provides an internal rate of return frequently north of 35 % over 5 years, based on finance models released by the German Machine Tool Builders’ Association (VDW).
Prepare a floor space of 3830 × 2250 mm and reinforce the foundation to withstand a point load of 70 kN/m². Electrical supply should be 400 V, 50 Hz, with a protected circuit of 32 A.
The TrumaBend V 850SX refurbished combines a still-competitive 850 kN force frame, a versatile 2720 mm bed, and battle-tested Delem control logic. Companies running mixed-material batches will appreciate the automatic crowning and fast tool lock, while plant managers keep operating costs in check thanks to the energy-saving drive. That is why mid-sized subcontractors, elevator manufacturers, and HVAC panel builders continue to sign purchase orders for the V 850SX long after TRUMPF introduced newer TruBend models. Investing in this machine today secures a dependable workhorse without tying up the budget required for a brand-new brake.
