Pass/Fail Checks for a CNC Hydraulic Press Brake FAT
A buyer's guide to defining practical factory acceptance test criteria for a 110 t, 3,200 mm CNC hydraulic press brake, with questions to put in the RFQ and demonstration.
For a 110 t CNC hydraulic press brake with a 3,200 mm bending length, the first buyer decision is which checks must pass before shipment and which can wait for site installation. A practical split is to make safety functions, control response, and repeatability pass/fail at the factory, while treating material-specific bend results as conditional on the test material and tooling agreed in the purchase order.
In the RFQ, ask the supplier to state the test material, thickness, tooling, and target angle for each demonstration, since the catalog values of 110 t bending force, 3,200 mm bending length, 200 mm beam stroke, and 410 mm throat depth are reference figures and may not describe the supplied configuration. For the demonstration, define measurable checks: does the ram stop at the commanded position, does the CNC display match actual angle within a stated tolerance, and does a repeated bend sequence hold that tolerance? Ask how pass or fail is recorded and who signs.
Before requesting a quote, confirm with the supplier which tests are included, what test material and tooling they will use, how deviations are documented, and whether acceptance criteria will be written into the contract.
