This invention discloses a method and an apparatus for grinding and polishing up a rod-like object which has such a comparatively small diameter that the rod is pliable when subjected to usual grinding. Upon grinding, it is placed on a horizontal, rotatable roll with a surface having great frictional resistance and held by a pair of parallel, opposed guide plates on both sides, where it is made to rotate by the rotation of the roll while a rotating grindstone is being pressed on it. Uniform grinding can be made by moving the grindstone and the rod-like object relative to each other along a gap between the parallel, opposed guide plates.
