Mark the length of taper on the roll ends. Increase the RPM's on the roll, carefully to a safe speed. Reduce the traverse speed as low as possible. Always start a taper on the face of the roll and traverse outward off the face. Turn the infeed slowly as the grinding wheel moves to the end of the roll.
