    Tools Sticking in Spindle.

    Suddenly tools are sticking in the spindle of our RH33 Mill, breaking off the plastic grabbers on the tool changer. Weve tried cleaning of course and adjusting thru spindle. Anyone else ever have this issue?

    I would try replacing your bellville washers on the drawbar and following the procedure for setting the "plunger" length that is in the procedures for the bellvilles. Also, make sure the oiler is full on your air supply. All of that fixed my sticking tools. Probably a quarter of my washers were cracked or broken, and my tools were sticking bad. Haven't had a problem for a couple years now.

    Make sure everything is clean, use Grey Scotch-Brite Pads in the spindle and on the Tool Holders

    Add some quality Grease to the top 1" of the Tool Holder taper, you will find that the top 1" of the holders has a slight swelling caused by the pull-stud being screwed in, have you used a torque wrench to torque the pull-stud or just with a hand wrench
