I was turning down a stress proof steel last night at 1400 rpm . I was set up using the livecenter and the dead center. After I finished a pass I shut off the lathe to take a measurement and I noticed that it had stopped very quick. Alot quicker then normal. The headstock area felt very warm , could this be a sign of the bearings going out. I did have the centers snugged up pretty good and was cutting towards the headstock so all the force was going towards the bearings. It has seemed to be a bit louder then normal but I have heard that the gear head drives are louder then belt drives.
It calls for 68wt oil in the head stock what would happen if a guy ran 100 wt. Would it be harder on the bearings. I was thinking about trying this 100wt the next time I change the oil.
