X
Rotate the RESM20 ring, measuring the radial
displacement at all of the screw locations.
X
Tighten the screw with the lowest radial displacement so
that it matches the average radial displacement, whilst
ensuring the maximum torque specified in the table is
not exceeded.
X
Again, rotate the RESM20 ring and re-check the radial
displacement at all of the screw locations, tightening
the screw with the lowest radial displacement so that it
matches the average.
X
Repeat this process until the radial displacement at all
of the screw locations is within ±3 µm and that all screw
torques are within the specified range.
X
Excessive tightening of screws can have a small effect
on accuracy. Please contact your local representative for
more details.
