To provide an apparatus and a method for working fine recessed parts by which the fine recessed parts can formed be on the outer circumferential surface of a workpiece in order to make friction low.
The apparatus for working the fine recessed parts, by which the fine recessed parts are formed on the outer circumferential surface Wa of the workpiece W, is provided with: a main shaft 3 which rotationally drives while holding the workpiece W and rotation driving; a working roller 5 which is provided with fine projecting parts on its outer circumferential surface and is supported to be freely related to a roller shaft 4; a coil spring 23 which presses the fine projecting parts onto the outer circumferential surface Wa of the workpiece W by imparting a load onto the working roller; and a load cell 6 which measures the load, wherein the fine projecting parts provided with the outer circumferential surface of the working roller 5 are inclined with respect to the roller shaft 4.
