Stylus
Spring pressure within the probe
causes the stylus to sit in one unique
position, and return to this position
following each stylus deflection.
Stylus pressure is set by Renishaw.
The user should only adjust spring
pressure in special circumstances
e.g. excessive machine vibration or
insufficient pressure to support the
stylus weight.
To adjust spring pressure, remove
the probe head to gain access to the
spring pressure adjusting screw.
Slacken the locknut, and turn the
adjusting screw anticlockwise to
reduce pressure (more sensitive)
or clockwise to increase pressure
(less sensitive).
A stop prevents damage, which
could be caused by overtightening
the adjusting screw.
Finally tighten the locknut to 1 Nm
(0.74 lbf.ft) and replace the probe
head.
ENSURE THAT THE OMP IS KEPT
CLEAN.
DO NOT ALLOW COOLANT OR
PARTICLES TO ENTER THE PROBE.
