[0002] Application No. 202223160725.6 discloses a processing fixture for deburring parts. During the polishing process, the fixture is equipped with a non-slip rubber pad at the bottom to prevent rotation. During the polishing process, burrs at specific locations on the surface of the shaft part body are removed. After the burrs at one location on the shaft part body are removed, the position of the shaft part body is adjusted again, and the burrs at other locations are removed again.
