Remember two things: First, Arc Seconds
change with power.
For 3- to 5-axis machining centers, Hamar's L-743 Ultra-Precision Triple Scan laser has three rotating laser planes that are perpendicular to 1 arc second
and flat to 1/2 arc second
in a 360 degree sweep and 1/4 arc second
in a 90 degree sweep.

Other near-misses include Arc seconds
for 1990 Niel winner Epervier Bleu and for the Group 1 Prix Vermeille scorers Magic Night (1991) and Leggera (1998).

Accuracy for the B and C axes is [+ or -]20 arc seconds
, and repeatability is [+ or -]15 arc seconds
