Abstract (en)
[origin: US4302909A] An apparatus for lapping an external circumferential arcuate face of a workpiece includes an axially split, radially resiliently expandable sleeve having an inner face constituting a lapping surface, an axial clamping arrangement for immobilizing the sleeve in a radially resiliently expanded condition. The apparatus has an operative state in which the sleeve is immobilized by the clamping arrangement in the radially resiliently expanded condition in which the inner diameter of the sleeve corresponds to a desired working diameter of the apparatus.
