The machine tool comprises a swing head, a spindle fixed to the swing head, and a ball cutter mounted at the end of the spindle, with the ball cutter's ball center centered on the swing head's rotation axis. The machine tool also includes a visual aid for detecting whether the ball cutter's ball center coordinates are aligned with the swing head's rotation axis.
