Abstract: As a deterministic sub-aperture magnetically assisted polishing method
Magnetorheological Finishing (MRF) has the ability to produce optical surfaces with high accuracy on a wide variety of shapes. This paper mainly introduces fundamental principle of MRF and summarizes some key problems in MRF process. Using KDMRF-1000 MRF polishing machine and KDMRW-1 water based MR fluids
one K4 flat work piece (100 mm in diameter) and one K9 sphere work piece (200 mm in diameter) are polished. Finally
work piece one is 55.3nm peak-to-valley (PV) value
5.5nm root-mean-square (RMS) value and work piece two is 40.5nm PV value and 5nm RMS. Also
surface roughnesses of two work pieces are improved obviously. Keywords: Magnetorheological Finishing (MRF)
