Touch Probe Concentricity
Probe “run-out” is the amount the probe tip moves an indicator as the spindle is rotated. Run-out adjustment is necessary
to ensure that the center of the probe tip is aligned with the center of the spindle rotation axis. This eliminates any unde
-
sired off-sets between the probe and the cutting tool centers when digitizing or doing automated part set-up.
When to Check Probe Run Out:
Any time the probe is removed from its holder, the stylus is changed or the probe is used in a different machine, the align

ment procedure should be repeated to ensure accuracy. The user should also repeat the alignment procedure if the unit is
dropped or receives any sudden external shock. It is good practice to periodically check alignment for quality control and
to establish a base line maintenance schedule.
