15522. NC-rotary table (optional)22.3 Setting the axial play of the NC-rotary tableThe axial play of the rotary table (2) is set using the limiting ring (4)To set, proceed as follows:7. Undo the four threaded pins (25) in the limiting ring (4) using a 2.5 mm Allen key.8. Tighten the four fixing screws (21) of the limiting ring using a 3 mm Allen key crosswise and medi-um-tight.9. The rotary table can now be rotated using a 5 mm Allen key pushed through the motor hood into thescrew (13) (only clockwise). The rotary table should only turn with difficulty or not at all.10. The four threaded pins in the limiting ring can now be used to set the play very finely.11. The threaded pins are tighten crosswise, in small stages, and the movement of the rotary table isconstantly checked by rotating with the Allen key.12. The play is set correctly when the rotary table can again be turned evenly without exerting consider-able force.Excess axial play of the rotary table may be the cause of dimensional deviations and bad surfacequalities.120321157626221413425218
