Supernishing is efcient for nishing cylindrical, at, spherical, and
conical surfaces. Although it is not suitable for changing dimensions, an
average stock of 0.005–0.030 mm in diameter can be removed (Table 9.9). The
high degree of surface improvement is achieved at a lower cost, compared
to other nishing methods, because only a short time is required to obtain
the nish and there are only a small percentage of rejected components.
As in the lapping process, the high quality of surface obtained in supern-
ishing is mainly due to
