ABSTRACT:
In this invention, the jig board fixing axis inserted in the eccentricity hole of the rotation axis rocks at rotation radius r without the rotation of the axis, the jig board set on the rocking jig board fixing axis is co-moved on through the spherical axis bearing, and then tip of the stick-like material is connected to the wheel spherical surface R by the self-weight of the jig board fixing axis and the jig board, ready to be ground and polished. And when the tip of the stick-like material connects orthogonally to the tangent direction of the spherical surface R, it is spherically processed by the rotation of the wheel and the rocking movement of the jig board.
