PLANE FRONTAL RECTIFYING MACHINE FOR RECTIFYING THE ENDS OF OPTIC FIBRES

摘要

Each workpiece holder of a grinding machine is reciprocated relative to and turned about an axis parallel to that of a wheelhead spindle. Workpieces carried by the holder are brought from in front of and to the side of an abrasive wheel front working surface into contact with the working surface. To prevent the pieces ground by the abrasive wheel from being scratched, after the workpieces have been ground, the wheelhead spindle is translated from a region where the grinding is performed. Simultaneously the workpiece holder is turned from in front to the side of the abrasive wheel working surface. The grinding machine, for instance, comprises two workpiece holders that are diametrally opposed with respect to the abrasive wheel. The holders turn in opposite reciprocating directions. The workpiece holders carry two half-holders for optical fibers having ends to be connected together. The ends of the fibers are simultaneously and coplanarly ground by the machine.
