Demonstrating a CNC Hydraulic Press Brake on Your Own Steel
A buyer's guide to planning a press brake demonstration around the buyer's actual steel workpiece, with practical checks on bending force, length, stroke, and throat depth before acceptance.
Ask the supplier to bend your own steel part, not a demonstration sample, before you accept the machine. A 110 t press brake with a 3,200 mm bending length, 200 mm beam stroke, and 410 mm throat depth may look adequate on paper, but only your workpiece reveals whether the tooling, control program, and handling fit your job.
For the demonstration, bring the thickest and longest parts you expect to form. Ask how the 110 t bending force is distributed across your bend line and whether your longest blank fits within the 3,200 mm bending length. Confirm that the 200 mm beam stroke covers your part height and tooling, and check that the 410 mm throat depth clears your flange geometry. Ask the supplier to run the CNC program you would use in production and to show how bend angles are corrected on your steel.
Treat these catalog values as reference figures, not guarantees for a supplied model. During acceptance, measure the first-off part against your drawing and repeat a short production run.
Before requesting a quote, confirm with the supplier which tooling is included, how the demonstration part will be fixtured, and what acceptance criteria will be recorded.
