Air bearing precision finishing method

The invention discloses an air bearing precision finishing method. The air bearing precision finishing method comprises the steps: in the period of precision finishing of an air spindle and an air spindle sleeve, according to the adopted technological process, firstly, the two working procedures of grinding with a circular table surface grinder and manual grinding are adopted for carrying out circular precision finishing on positioning end faces, in other words, one end face is manually ground after being ground with the circular table surface grinder, and the other end face is manually ground after being ground with the circular table surface grinder; then, accurate grinding is carried out on an inner hole and the excircle, and after low-temperature aging treatment is carried out, the working procedure carried out on the air spindle sleeve is glow-ion nitriding surface treatment; the two working procedures of grinding with the circular table surface grinder and manual grinding are adopted again for circularl
