A dressing roll unit is supported on a nonrotating shaft clamped and maintained as a 'fixed end' beam, thereby restrained against axial movement and deflection. The shaft is formed with spaced-apart bearing points, wherein wedge-shaped relief sectors are formed about the shaft at the bearing points, and a roll body is maintained about the bearing points with an annular clearance. Rotation of the dressing roll body and roll thereby forms high pressure hydrodynamic wedges of oil at the relief sectors and annular clearances, to create an extremely rigid roll mounting unit, without the need for pivoting bearing parts.

Roll-type dressing unit

An angled cam bar is slidable across a pair of base-carried supports so that the cam bar attitude varies in its travel, and a pivot point on the cam bar thereby traces out a locus of curvature, while a dressing stylus depending from the pivot point likewise traces out the locus of curvature on a grinding wheel. The supports are biased to a first position so as to generate a first portion of the locus of curvature, and means as provided to move one of the supports at one end of the first locus portion so as to generate a second portion of the locus of curvature as the bar continues traversal.
