ABSTRACT:
In an apparatus (20) for end finishing an assembly (22) comprising a plurality of lightguide fibers (23--23) positioned between two silicon chips (26--26), a tool carriage (45) is moved past the assembly which at first is held in a fixed position with respect to a path of travel of the carriage. A profiling wheel (110) which is mounted rotatably on the carriage severs a portion of the chips and fibers from the assembly to provide an end portion having a predetermined end configuration. Subsequently, a grinding wheel (131) and a polishing wheel (141) are moved past the newly formed end of the assembly to grind and polish a surface of the end portion and ends of the fibers which terminate in the surface. These last two operations are accomplished while forces are applied to the assembly to bias it toward the tool carriage to provide a controlled pressure and avoid the removal of excess material from the surface and fibers.
