Abstract:
1. A fluid polishing method for polishing and processing a fine aperture in a work by supplying slurry as a polishing fluid to said work by a feeding apparatus, comprising a primary process, a secondary process and a finishing process, wherein: in said primary process, said slurry is supplied until a slurry feed flow rate from said feeding apparatus increases to a predetermined value smaller than a predetermined slurry flow rate necessary for processing said fine aperture, said feeding apparatus is then stopped to stop the feed of said slurry, an operation fluid is caused to flow to the fine aperture of said work and a first operation fluid flow rate (Q in said second process, a second processing time (T in said finishing process, a target third processing time (T the processing time (T said processing capacity coefficient (K) is a function (K=f(x), x=dQ/T) of a ratio (dQ/T) of an increment amount (dQ), of the operation fluid flow rates during processing, to said processing time (T
