Abstract
A method of grinding rough-shaped spherical objects to a finished spherical form comprising the steps of freely supporting the rough-shaped spherical object on one end of a vertically oriented tube. This one end is open and has an inside diameter such that a segment portion of the object lies within the tube. Next, an abrasive is applied to the surface of the object, and the object is ground by vibrating the tube axially at a frequency in the range of approximatelly 20-25 KHz, whereby the surface of the object is ground to a truer spherical shape.
