Grades of Accuracy
Tolerances for run-out accuracy and axial run-out accuracy corre-
spond to the Technical Supply Terms for lathe chucks as per DIN
ISO 3089.
Permissible imbalance
The ROTA TP in ungreased state without T-nuts and top jaws cor-
responds to the balancing quality class 6.3 (according to DIN ISO
1940-1). Risks of residual unbalance 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 top jaws, as well as uneven application of lub-
ricants. In order to prevent damage resulting from these residual
risks, the entire rotor is to be dynamically balanced in accordance
with DIN ISO 1940-1.
