ABSTRACT:
An overhead radius dresser for grinding wheels for surface grinders has a housing mounted upon the wheel spindle supporting a reciprocally rotatable main shaft mounting a slide having a central axis coincident with the grinding wheel plane. A slide housing is mounted upon the slide plate and adapted for movements upon a transverse axis. A radially adjustable slide arm depends from the slide housing for determining the radius of dressing the grinding wheel, and supports a depending diamond holder arm mounting a diamond tool which on selective rotation of the main shaft in opposite directions from a central position causes the tool to dress the grinding wheel radius in either direction and successively on additional transverse movement of the slide housing until stopped causes the diamond tool to sweep tangentially over the respective outer angle portions of the grinding wheel. Stop screw means including a pair of reciprocally movable pins is mounted upon and is interposed between the slide plate and the slide housing to facilitate stopping at the centerline and for tangential surface dressing of the tangential angles of the grinding wheel.
