I have a Acer knee mill with very few hours, but recently have been getting bad finishes, seemed like a bearing problem despite faithful oiling with Velocite #6.
I took the spindle out to replace the bearings with a kit from H+W.
The upper bearing was sealed(not shielded) . I thought oil was supposed to flow from oil cup thru the upper (non-precision) bearing down to the two lower ABEC 7 bearings? Not sure where the oil I was putting in was going, I would routinely see clean spindle oil on the table under the spindle, but the two lower spindle bearings just had original grease and no oil. I oil all three cups every day.
Can someone confirm this cup under the Hi:low gear lever is for the spindle bearings( and flow is like I described?)
Thanks!
