Abstract:
An end surface polishing drive mechanism comprising:a first rotational shaft mounted for undergoing rotation about a first axis and for undergoing revolving movement about a second axis offset from the first axis, the first rotational shaft having a first end for connection to a polishing member during use of the end surface polishing drive mechanism to rotate and revolve the polishing member about the first and second axes, respectively; a second rotational shaft for undergoing rotation about the second axis; support means for supporting the second rotational shaft to undergo free rotation about the second axis; drive means for rotationally driving the first rotational shaft and the second rotational shaft; a first gear connected to a second end of the first rotational shaft opposite the first end thereof; a second gear comprised of a second regulation gear rotatably mounted on the second rotational shaft for meshing engagement with and disposed along a locus of movement of the first gear to transmit a drive force of the drive means to the first rotational shaft; a jig board for supporting at least one workpiece having an end face; and a movable support mechanism for supporting the jig board and for moving the jig board to bring the end face of the workpiece into pressure contact with the polishing member to thereby polish the end face of the workpiece during rotation and revolving movement of the first rotational shaft.
