Afterward, time strode over me slowly, just like the road roller runs over the surface of an asphalt pavement that was not enough smooth.

Under high speed lightly loaded conditions, skidding damage often becomes one of the main damage forms for cylindrical roller bearings while surface roughness has great effect on skidding damage.

Thus, working roller to perform uniform accurate grinding has not become true for roller surface rigidity and ORG grinding wheel rigidity fluctuating result in excessive or deficient roller grinding.
