Abstract: Ultra high speed shafts are used for cryogenic applications. In this research work, an attempt has been made to finish two shafts simultaneously to the same level of finish using MAF. A setup has been developed to accomplish this objective, and employs the principle similar to that of MAF for external cylindrical surfaces. This paper introduces the new concept of central magnetic core in MAF. Two shafts each having an initial surface finish of 0.7
