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.
Permissible imbalance DIN ISO 21940-11
The ROTA NCX in ungreased state without chuck jaws corresponds
to the balancing quality class 6.3 (according to DIN ISO 21940-11).
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, asymmetrical workpieces or the use of
various chuck 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 21940-11.
