In mechanical products, many shaft bushings tend to have shorter lengths, smaller inner bores, and higher coaxiality and tolerance requirements for inner and outer circles. After the inner hole is finished in the inner hole, the outer circle is clamped by a common mandrel, and it is often difficult to ensure the quality well. The high-precision expansion shaft is used to position and expand the inner hole of the workpiece. The perfect round and fine semi-finished car are an ideal processing method.
