Flo,
that machine is not cheap
and is precision
it uses a Heidenhain controller so it has precision feedback (it will
use Heidenhain scales )
and you can get great information about how rigid it is from
DeckelMahoGuildemeister
the bearing around the whole B axis is impressive, it will take the
cutting forces
Please keep us posted with this projects progress
that is one sweet machine tool
