My Bridgeport style heads have class 7 bearings with a labrynth seal in the bottom nut that screws into the bottom of the spindle. The bottom bearings (2 angular contact ball bearings) are lubed with Kluber NBU15 grease. I would recommend this to anyone with a mill spindle. It stays in the bearings without any problems.
When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the ...
