Optical fiber connector ferrule end face polishing plate and polishing apparatus

An optical fiber connector ferrule polishing plate (1100) includes a polishing plate including a disk-formed substrate, a ring grinding wheel (3) provided on an outer peripheral portion of a surface of the substrate and for forming an adhesive removing ring area (I), a first elastic film polisher (6) provided on an annular portion inside the outer peripheral portion of the surface where the ring grinding wheel (3) is provided and at a distance from the surface of the substrate, the first film polisher forming a rough polishing ring area (III), and a second film polisher (6) provided inside the annular portion where the first film polisher is provided at a distance from the surface of the substrate, the second film polisher (6) forming a final polishing ring area (IV), whereby the polishing plate is rotated to polish the end face of the ferrule with its surface. Further, a polishing apparatus (2100) includes a polishing plate (10); a chuck (30) for holding the optical connector ferrule (220) at a position opposing the polishing plate and rotated about the axis of the ferrule held by the chuck (10); a mounting substrate (32) having an end opposing the polishing plate (10), the end rotatably supporting the chuck (30); a moving part (37) movable in the rotary axis direction of the polishing plate (30); whereby the polishing plate (10) or the mounting substrate (32) connected to the moving part (37), the end face of the ferrule (220) held by the chuck (30) is pressed against the polishing plate (10), and a concave pressure between both parts is controlled according to a concave set or a concave force.
