Lens polishing devices that have been commonly used can be roughly divided into two types, depending on whether the direction in which the holder shaft (hairpin) is inserted always presses the spherical core of the polishing plate or not. The present invention belongs to the latter category, and is primarily an apparatus for polishing lenses by swinging the spherical core of the polishing plate. In these conventional devices, there are two methods: one in which the center of rocking motion is the spherical center of the lens R and the polishing plate R, and the other in which the holder shaft is swung toward the spherical center. Since the lens is always subjected to unbalanced pressure, it not only worsens the reproducibility of the lens.

Since the polishing plate wears out very quickly, it is necessary to frequently readjust the MR and readjust the swing angle and inside. In addition, although the latter poses no problem in the case of four lenses, many problems arise when polishing a convex lens.
