The dressing disk 5 in Figs. 1 and 2 has several design parameters in order to restore fixed abrasive polishing materials back to their original state. In Fig. 1, the dressing disk is made of a base metal of aluminum 1. This base metal exactly duplicates the physical parameters of the substrate being polished except for the thickness. The thickness usually has to be 100-250 mils thick to maintain perfect flatness. The base metal surface 2 must first be conditioned before the dressing material can be applied. This can be accomplished in two manners -- grinding or sand blasting the surface to a roughness in the 200 microinches AA region. This step is necessary to improve the adhesion characteristics of the dressing material.
