The part I'm currently making is short and has a center through hole so quite a bit of coolant gets into the sub spindle and it's coming out around the part ejector assembly. The sub spindle has a Kitagawa hydraulic chuck cylinder with a coolant sump so i think the coolant ought to be going down that pipe. I think it may be clogged up. I took the part ejector assembly off and where it was bolted to there is an aluminum ring that bolts to the back of the Kitagawa hydraulic unit (doesn't turn) and a steel ring that turns with the spindle (center black part in photo below). The part ejector assy bolts to the aluminum ring. I got the 7 of the 8 screws that hold the aluminum ring in place out. The head stripped on the 8th so I had to drill the head out. This ring is now loose but won't come off. I think it's being held in place by a flange on the steel ring. Can't figure out how the steel ring is held in place. I wonder if it's threaded to the spindle? I know there a few folks on here who have similar machines so I'm posting to see if anybody has been into this before. The Miyano assembly drawings are not very good and I can't really tell from them.
