I have a RF31 mill drill and I need to replace the spindle bearings. A little stiff and heat build up. The mill has always left a scalloped finish when side milling only a few tenths deep. Easy enough to remove with emery or a file, but I would like to improve or eliminate it. I don't expect it finish like a Bridgeport class mill. Don't know if this is caused by the class of bearing used in this machine or a vibration problem or both. Really doubt if precision bearings are used in this machine, and it certainly could be something else. Has anybody run into this problem and was able to fix, or improve it?
Thanks,
Dave
