Claims
- 1. A surfacing pad for use on a curved surface of a lapping tool having an aperture which extends below said curved surface, comprising:
- a substrate sheet having an overall annular shape with radially extending slots to allow said pad to conform precisely to the curved surface of the lapping tool and projection means extending from said pad, said projection extending transverse to the pad, said projection adapted to couple with the aperture in the lapping tool;
- said projection means having an open center with radially outwardly extending channels, said channels extending longitudinally the length of said projection to thereby provide at least a pair of spaced segments hingedly connected at a first end adjacent the substrate sheet for forming a hinge means, said hinge means for enabling radially inward movability of the segments when inserted into the aperture, such that the segments are hingedly movable with respect to one another for enabling conformance of the underlying surfacing pad to the curved surface of the lapping tool at the projection means location.
- 2. The surfacing pad of claim 1 wherein said projection means are separated from one another by diametrical channels.
- 3. The surfacing pad of claim 2 wherein said projection means further comprises four segmented portions.
