So is this different machine or for the RF45.
You will need to balance the TTS tool holders to spin that fast, which will require sending them someplace. Balancing them to 24K will be non-trival. You will also need to balance the whole spindle assembly once installed - and that takes some pretty serious equipment. Otherwise you will just toast bearings all the time running that fast with that much mass.
Our 16K RPM BT30 taper spindle at work was balanced at the nose and mid span with a sophisticated laser/vibration based balancing system once the machine was installed and level.
