Conguration of the Base Structure
15.4 Conguration of the Base Structure
15.4.4 Parallelism Tolerance of the Reference Surfaces for MINIRAIL and
MINISCALE PLUS
Guide rails which are not aligned in parallel cause unplanned loads in the guide
system over its stroke length, subsequently subjecting the tracks to additional
stress. This decreases running accuracy of the guideways and can shorten the
service life. The parallelism tolerances Δ below must therefore be adhered to.
