FAT Checks for a CNC Six-Sided Panel Drilling Machine
Buyers should define measurable pass or fail checks for drilling accuracy, six-face coverage, and tool changes, using catalog ranges only as reference values to confirm with the supplier.
A buyer signing off a CNC six-sided panel drilling machine should decide in advance which checks must pass before shipment, and write them into the factory acceptance test rather than relying on a demonstration run.
Start with the working envelope. The catalog lists panel thickness of 10–60 mm, width of 30–1,220 mm, and length of 200–2,800 mm; treat these as reference values and ask the supplier to confirm the tested range for the offered model. Then agree sample panels at the thin and thick ends and at the narrow and wide limits, and state how many pieces must be drilled on all six faces without repositioning errors.
For accuracy, define a measurable criterion: for example, hole position deviation on a stated sample size, checked with a named method. For the 6-tool magazine, require a tool change sequence covering every station and record whether any change fails or needs manual intervention. Ask whether the acceptance test uses production programs and production clamping.
Before requesting a quote, confirm with the supplier which checks it will run, the sample materials and dimensions, the measurement method and acceptance limits, and who witnesses and signs the test report.
