Original instructions
Insert screws into the remaining mounting holes.
•
Rotate the RESA30 ring, measuring the radial displacement at all of the screw locations.
(Nm)
•
Tighten the screw with the lowest radial displacement so that it matches the average radial displacement, whilst ensuring the
1.5 - 2.1
maximum torque specified in the table is not exceeded.
0.8 - 1.1
•
Again, rotate the RESA30 ring and re-check the radial displacement at all of the screw locations, tightening the screw with the
0.5 - 0.7
lowest radial displacement so that it matches the average.
1.2 - 1.7
•
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.
•
Excessive tightening of screws can have a small effect on accuracy. Contact your local Renishaw representative for
more details.
•
Clean the ring using Renishaw scale cleaning wipes or a clean, dry, lint-free cloth.
