Floating reamers are often used in the machining of holes, especially in the machining of box holes. Because of the convenient radial dimension adjustment of the floating reamer, the machined hole can achieve higher dimensional accuracy and lower surface roughness. The floating reamer is installed in the square hole of the mast. As the precision of the hole to be machined is improved, the matching precision should also be improved. The square hole of the mast has higher requirements on the (?) degree, parallelism and perpendicularity of the mast axis. . Only the center of the reamer blade is mounted on the mast and the hole
