PURPOSE:To improve dimensional accuracy of a work by its stable contact pressure, by correcting a locus to polish the work by a fixed pressure in accordance with a program containing a moving instruction in which a detection signal of elastic change in X, Y, Z axis directions of a wheel rotary shaft is converted by a computer. CONSTITUTION:A fixed pressure polishing head under a condition of polishing time X4-X7 detects a change corresponding to a resultant displacement preset value E0 as a displacement detection signal, and the displacement detection signal, being distributed by a distributor into each axis component and compared with a command register of each axis, corrects an instruction value of the work processing program previously input to a computer. That is, the surface of a wheel draws a moving locus S2, in which a correction part DELTAE1-DELTAE4 is added to or subtracted from a moving locus S1, as a result holding a contact pressure P to a fixed level b'. Accordingly, work surface accuracy is improved by polishing a work under stable application of the fixed contact pressure.
