A device for shaping an object with a profile of at least partial sphere defined by a radius, Rsph and a maximum breadth, Dmax of the sphere comprises at least one featured frame. A cutting element has been substantially positioned on a position located within a circular orbit by the featured frame and shaped with at least a portion of circular cutting edge with a uniform radius, rCE, which is able to free spinning-able on its spinning axis while, simultaneously the featured frame revolts on a circular orbit around the polar axis of the spherical object. The circular orbit of each cutting element is defined as a motion track of a circular center of the cutting edge around the polar axis and characterized by a radius, rorb, and a tilted angle α, thereof.
