Bowling ball surface abrading and polishing tool assembly

Abstract

This invention consists of a two-component cylindrical tool assembly suitable for contour rough abrading, texturing, fine surface abrading and extra fine polishing of a spherical surface. The tool body, fabricated from a rigid material, is smaller in diameter than the spherical object being abraded. The abrading cylindrical component, made from a molded and cured thermosetting resin material, is filled with diamond abrasive particles. The two components are assembled with their axis of rotation concentric with each other. The amount of surface abrasion and quality of surface finish imparted to the object during the operation is directly related to particle size, uniformity of size, quantity of the abrasive particles used, and the uniformity of their dispersion throughout the molded abrading cylinder. The cylinder face that extends beyond the body component is machined to match the spherical radius of the bowling ball or similar object, defining the annular region of spherical contact. Surface abrasion between the invention and spherical object occurs when the invention is rotating and the object is either held stationary or is rotating. Surface abrasion will also occur when the spherical object is rotating and the invention is not rotating but traversed across the object's rotating surface, perpendicular to the rotational direction. Machined holes on the body face opposite the abrading cylinder adapt the invention for various mechanical or hand tool options.
