I am doing some cylindrical grinding on a K. O. Lee Univ. tool and cutter grinder. I am grinding a 1" dia 4140 steel round. The wheel is a new Norton 6" 32A 60grit K, freshly dressed front and sides . The part is in a motorized spin fixture between spring loaded dead centers running reverse to the direction of wheel rotation and am using coolant. After spark out, the finish to the naked eye looks great, but under a loupe, it has a tiny longitudinal flutes like slats on a barrel. Bad bearings, wrong wheel?
I am a complete novice at grinding and any help appreciated.
