X
Insert screws into the remaining mounting holes.
X
Rotate the RESM20/REST20 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/REST20 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 Renishaw
representative for more details.
