Mid-frequency surface error controlling the polishing process is not conventionally concerned as the same of controlling of low-frequency surface error. In order to solve such a problem  a new method - Multi-mode Combined Manufacturing (MCM) is put forward. MCM technology is useful for the control on all frequency-bands errors of optical surface and is adaptive to fast aspheric mirror especially. Based on classical manufacturing theory  principle analysis of MCM and experiments results are discussed in the paper.
