This job comes through my shop a couple times a year; reconditioning carbide guide rolls on a Monoset. I use a Norton ASD 120, type 11V9, 3 3/4" cup wheel at 8000 rpm. Work head is running about 80 rpm. Grinding one side of the "V" at a time.
The surface finishes always look like the pictures unless I really slow down the cross-feed on my finish pass to .0001 doc & feed .001" per rev. I can get a very nice surface finish but the finish pass takes as long or longer than it does to rough .010 off a side.
The wheel spindle was rebuilt 1-200 hundred hours ago by Sopko. Does this look like bad workhead bearings? Maybe it would be faster to polish with diamond lapping compound?
