The master spheres are manufactured from high
chrome, high carbon stainless steel that has
ultra fine grain structure. The master spheres
are hardened to 58 Rc and thermo cycled for long
term dimensional stability. The 3/4 inch (1.9cm)
diameter tubular steel construction provides a
very rigid light weight structure. The Ultra
Precise Stainless Steel spheres are attached to
the ends of the Ball Bar (Dumbbell) by gluing. A
steel pin is inserted into a drilled hole in the
master sphere and in the bar as the high strength
glue is applied during assembly. The result is an
exceptionally strong, shock resistant, bond
between the master sphere and the bar.

The two support spheres are held in two magnetically
pre-loaded kinematic couplings attached to a very rigid
tee shaped aluminum rail of the Way Out Ball Bar
(Dumbbell) Support ( see Technical
Data Sheet C.M.M.-16, Page 2.). The first kinematic
coupling consists of three precision spheres arranged in
a circle to form a three contact cup. The second
kinematic coupling consists of two precision cylinders
that form a dual contact cradle. Each of these kinematic
couplings has a powerful rare earth magnet implanted just
below the surface in the center of the coupling.
This design constrains five of the six degrees of Ball
Bar freedom without introducing any over constraint.
The Cantilever design provides three outstanding
advantages over the conventional free standing Ball
Bar.
The most important advantage is the very rigid support
it provides. This design virtually eliminates any of the
deflections caused by the contact force of the measuring
probe.
The second advantage is that the master spheres are
never contacted by the kinematic couplings which might
cause scratching, wear or brinelling.
The third advantage is that the entire surfaces of the
master spheres are exposed for evaluation by the C.M.M.
measuring probe.
The Cantilever Ball Bar is usually used with The Way Out Rail, see page: CMM-16,
