ABSTRACT:
A process is disclosed for forming a spherical component using a centrifugal processing machine. The process includes the steps of providing a component having an initial shape with at least a portion that is non-spherical, placing the component into a container in the centrifugal processor, adding a first stage abrasive media into the container, and rotating the container so as to produce centrifugal and rotational motion of the abrasive within the container. The motion of the abrasive causes the component shape to change from the initial shape to a substantially spherical shape through the repeated contacting of the component's surface by the abrasive. In one embodiment, the components are further processed in a second stage using a different media to polish the surface of the component.
