Thread: Unimat 3 Vertical Head Quill
01/11/2015 23:27:08

Thank You for a very informative and helpful post I don't have access to that issue of ME, but I think I understood quite clearly anyway. I does not feel right to modify the quill so making a new spindle is probably the way to go, but I think I'll try to use a commercial bearing instead if making my own. Provided I can find something that fits. Hopefully someone developed a bearing with suitable dimensions in the almost 20 years that passed. Again, thanks for taking your time to describe the modification!

I had some free axial movement as well, and I fine-tuned it with a hammer at first, but then I decided to take it apart. The bushing closest to the spindle thread was slightly more worned than the top bushing, and since they have the same dimensions I decided to shift them. The mill runs a lot better now, but I sure would like to replace the bushings. In what issue was the rebuild of the quill described? What kind of bearings was used? Did they thread the top to get the preload? The only bearings I've found that would fit is F6802 (15x24x5 with 26mm flange) or 61802 (same dimensions but without flange). The bushings has ID 15, OD 20, depth 12 with a 25,5mm flange. The outer diameter of the quill is 32mm so boring it to 24mm would be possible.
