On nearly every TruBend KD Machinery has listed, the digits after the first one match the tonnage in metric tonnes, so a TruBend 5170 is listed at 187 US tons, which is 170 tonnes. KD Machinery buys and sells used TruBends from a 55-ton 7050 with a 5-foot bed to a 660-ton 8600 with a bed of almost 20 feet, built from 1999 to 2021.

Reading a TruBend model number
The first digit groups the machines into the 3000, 5000, 7000 and 8000 models on KD Machinery’s record, such as the 3100, 5170, 7050 and 8600. The digits after it follow the metric tonnage, while the listing gives US tons, so a TruBend 5085 is listed at 94 tons. The number says nothing about the bed. A 5170 on KD Machinery’s record has come with a 10-foot bed and with a bed close to 14 feet, so read the bed length and the distance between housings before you compare two machines.
Which control you will find
The control follows the series and the year more than anything else. Wherever the listing names the control model, the 5000-series TruBends KD Machinery has listed from 2008 to 2015 run the Trumpf Tasc 6000. Most of the newest machines on the record, built in 2020 and 2021, carry the TouchPoint TruBend touchscreen. Some 3000-series machines and the big 8600 have appeared with Delem controls instead, and the 1999 V130 with a Delem DA-65. Ask which control and which software options are on the machine, because bending programs and the shop’s offline software have to match it.
What to check on a used TruBend
Throat depth is 16.5 inches on most of the TruBends KD Machinery has listed, so a deeper box or flange will need a check against the drawing. Run the ram through a full stroke and look for leaks at the cylinders and valves. Bend a test part across the full length of the bed to see whether the CNC crowning holds the angle in the middle. Move every backgauge axis to its limits; four-axis and six-axis gauges both appear on the record. If the machine has hydraulic tool clamping or angle measurement, see it working, because those are expensive to repair.
Other press brakes and Trumpf pages
To compare a TruBend with other makes, see used Amada press brakes, used Accurpress press brakes or all used press brakes, and the press brake buying guide covers what to check on any brake. Trumpf lasers have their own page, used Trumpf TruLaser, and the Trumpf manufacturer page lists every Trumpf machine KD Machinery has.
