1. A grinding wheel dressing assembly comprising: a driving gear rotatable about a central axis, the driving gear including driving gear teeth on an outer circumferential surface; a dressing ring surrounding the driving gear, the dressing ring including dressing ring teeth on an inner circumferential surface and engaging the driving gear teeth, wherein rotation of the driving gear about the central axis results in rotation of the dressing ring about an offset axis, which is offset from the central axis, wherein the dressing ring includes a contact surface adapted to remove dull CBN particles from a substantially planar grinding surface of a grinding wheel that comes into contact with the contact surface; an outer ring having an interior circumferential surface; and a bearing insert having an inner substantially circular bearing surface and an outer substantially circular surface, the inner substantially circular bearing surface bearing against an outer circumferential bearing surface of the dressing ring and the outer substantially circular surface of the bearing insert engages with the outer ring to fix the bearing insert with respect to the outer ring.
