An optical fiber connector polishing apparatus is disclosed which comprises a polishing element rotated at high speed, a chuck for supporting an optical fiber connector in such a manner that the optical fiber connector is rotatable in a reciprocation mode, a swing arm which holds the chuck to swing the chuck, in a horizontal plane, between a first fixed position and a second fixed position, a positioning unit for positioning the swing arm selectively at the first or second fixed position on the swing locus thereof, a swinging unit for swinging the swing arm in a horizontal plane continuously while the end portion of the optical fiber connector being polished with the polishing element, and a reference member for positioning the end portion of the optical fiber connector at a reference position. The polishing element and the reference member are arranged at the first and second fixed positions of the swing arm, respectively. After, at the second fixed position, the end portion of the optical fiber connector is positioned with the reference member, the swing arm are moved to the first fixed position to polish the end portion of the optical fiber with the polishing element.

Optical fiber connector polishing apparatus and method

An apparatus for conically machining an optical fiber connector is disclosed which comprises a grinding wheel rotated at high speed, an optical fiber connector having end portion whose machining end face is confronted with the grinding wheel, and having an optical fiber along the central axis thereof, a supporting member for supporting the optical fiber connector, which supporting member is swingable towards the grinding surface of said grinding wheel, a driver for swinging the supporting member to cause the optical fiber connector to abut against the grinding wheel, a moving unit for linearly moving the grinding wheel along the axis of rotation of the grinding wheel until the machining end face of the optical fiber connector is shifted from the grinding wheel, a reference surface juxtaposed with said grinding wheel, to set said optical fiber connector, and a reciprocating rotation unit for rotating the optical fiber connector in a reciprocation mode through at least 360.degree. with the optical fiber at the center of rotation.
