ABSTRACT:
In superfinishing a Gothic-arch-shaped groove of a nut by using a superfinishing stone attached to the tip end of an oscillation arm while oscillating the superfinishing stone about the oscillation axis and, at the same time, moving the superfinishing stone in the longitudinal direction of the Gothic-arch groove, the oscillation axis is inclined by a predetermined angle with respect to the longitudinal direction of the Gothic-arch groove. The shape of the cross section of the Gothic-arch groove orthogonal to the oscillation axis is regarded as a single circular arc and, thus, both flanks of the Gothic-arch groove can be superfinished simultaneously.
