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). -
Page 27: Function
When determining the necessary clamping force to machine a workpiece, take the centrifugal force acting on the chuck jaws into account (according to VDI 3106). If the chuck jaws are changed, adjust the stroke control to the new situation. 02.00|ROTA TP |en... -
