Aiming at the problem of ultra-precision polishing of the bore surface of the elbow, a new ultra-precision polishing instrument is designed, which is suitable for the inner hole finishing and finishing of the elbow, and is placed in the cavity of the work piece, the flexible line connecting spherically spraying ultra-precision polishing instrument. And the simulation analysis of the polishing process in the elbow is carried out by ANSYS 11.0 finite element analysis software. It is verified that the polishing instrument can finish the ultra-precision polishing of the internal surface of the elbow, and achieve the purpose of the internal surface roughness reduction.
