Technical data
6.4 Grades of Accuracy
Tolerances for radial and axial run-out accuracy correspond to the
Technical Supply Terms for lathe chucks as per DIN ISO 3442-3.
6.5 Permissible imbalance
The ROTA NCO2 in an ungreased condition without T-nuts and top
jaws corresponds to the balancing quality class 6.3 (according to
DIN ISO 21940-1).
Residual imbalance risks may arise due to insufficient rotation
compensation being achieved (see DIN EN 1550 6.2 e). This applies
particularly to high speeds of rotation, asymmetrical workpieces or
the use of different top jaws, as well as uneven application of
lubricants. In order to prevent damage resulting from these
residual risks, the entire rotor is to be dynamically balanced in
accordance with DIN ISO 21940-1.
