Abstract
A surface finishing apparatus for disks and the like characterized by an eccentric spindle of small diameter engaging the inner circumference of a disk; a drive mechanism engaging the outer circumference of the disk to rotate the disk around an axis parallel to but not coaxial with the spindle; and a finishing mechanism which extends fully between the inner circumference and the outer circumference of the disk. Because the diameter of the spindle is less than the diameter of the center aperture formed by the inner circumference of the disk, a gap is formed. The finishing mechanism has a first edge disposed within the gap and has a second edge beyond the outer circumference of the disk. Thus, a full surface finish is provided by a stationary finishing mechanism. The finishing mechanism traverses a segment of the disk that is parallel to a radius of the disk. A transport mechanism is provided to move an unfinished disk to a finishing station for processing, and to remove a finished disk from the finishing station. The finishing mechanism includes an elongated, abrasive tape which can be looped against itself to remove large particles prior to its contact with the disk.
