FAT Checks for a CNC Gantry Surface Grinder

A buyer specifying a CNC gantry surface grinder for steel should decide in advance which acceptance measurements will be pass or fail, rather than accepting a demonstration of motion alone. Start with the work envelope: the catalog reference lists a maximum grinding length of 2,000 mm and a worktable of 2,400 × 950 mm, so ask the supplier to state how the usable grinding length is measured and where the limits sit on the table.

For load, the reference table load is 2,000 kg including workholding. Agree a test load within that figure and confirm how the machine is checked for table deflection or level change under it. For the spindle, the reference motor is 18.5 kW; ask what no-load run and load checks will be recorded, and at which points.

Useful questions for the RFQ or FAT: Which geometric checks are performed, with what instruments, and what values count as pass? Will a sample steel workpiece be ground and measured for flatness and surface finish, and who supplies the material? What acceptance criteria apply to CNC positioning and repeatability?

Before requesting a quote, confirm with the supplier which checks are included in the standard FAT, which require extra time or material, how results are documented, and what remedy applies if a check fails.
