I have a job coming up that I am going to have to cut a 6" deep depression in a part sort of like a bathroom sink shape but bigger and with no drain in the bottom. To avoid crazy long endmills or toolholders I was planning on having the spindle nose go down into the part. I often do this with our routers on wood patterns, I model the nose as part of the toolholder for simulation to ensure I don't get any collisions.
It occurred to me this week that the nose will be running in coolant if I do this. Hopefully just the toolholder but maybe the actual nose of the machining center. Its a high speed spindle 24000rpm. Is running in the coolant going to cause bearing issues? Or will the toolholder act as an impeller and keep the coolant away from the nose? I will have hours of surfacing.
I am also concerned about clearing the chips I suspect the coolant spray is not going to do much under 5-6 inches of coolant. any suggestions for clearing chips in this situation? Material is 6061 so I don't want to try running dry.
