I have two mills using r8 taper spindles. I have a Bridgeport Boss CNC type setup on one mill with a QC40 with a solid spindle. I want to change the Bridgeport to use the same tooling as the other two. Because of the spacer where the servo connects to the downfeed, the old spindle was longer than a standard series 1 spindle. When I put the standard spindle in, I can only extend the quill a few inches before it disengages from the spline in the head. Is there a longer R8 spindle for these type setup or is there a QC with the same taper as an R8 and a hold for a drawbar? I understand that QC is better than R8 for speed but we have a very limited budget and being able to swap jobs and tooling makes a lot of sense.
