Zusammenfassung:	An apparatus for lapping a portion of an exterior surface of a housing is described. The apparatus includes at least a lapping tool arranged to execute a lapping operation. The lapping tool takes the form of a lapping pad which includes a conduit through which slurry can be transported for local deposition on the housing during a lapping operation. The apparatus also includes a stage on which a workpiece in the form of a housing is mounted. During the lapping operation, slurry is passed through the slurry conduit in the lapping tool, the lapping tool and the housing are moved in various motions. In this way, a gradual transition region is created between an accessory region and the remainder of the housing.
