Conditioning means both the dressing and the sharpening of grinding wheels. In many cases, only a combination of both methods will provide satisfactory results in terms of grinding wheels.

The following details relate mainly to the conditioning of the bond variants resin B, metal M and metal-vitrified MV. The requirements for dressing vitrified bonds are different from those described in the chapter „Vitrified Bonds".
Dressing 
Dressing in this context means the recovery of the grinding rim geometry and the correction of plane and radial run outs (eccentricity).
Conventional silicon carbide wheels are used for dressing B, M and MV bonds. The choice of the proper dressing wheel with respect to grit size and degree of hardness depends on the grit size of the Diamond or CBN grinding wheel to be dressed. The overview below shows the appropriate details.
