Abstract
Methods and systems are provided for design and manufacture of a non-metallic polishing tool capable of polishing different surfaces and achieving a smooth and shiny finish. The polishing tool comprises an abrasive coated base surface, and a plurality of engravings in the base surface, forming cylindrical pillars. The pillars are arranged in concentric circular patterns to provide uniform polish and shine on a target material.
Claims13
A polishing tool comprising:
- a base surface;
- and
- a plurality of engravings in the base surface;
- wherein the engravings form a plurality of pillars, the pillars arranged in concentric circular patterns forming repeating unit cells;
- wherein each of the pillars with diameters between 100 nm-500 μm in the repeating unit cells includes a top surface with an abrasive material and a side face forming an angle with the top surface, the angle is between 75-90 degrees;
- wherein a pitch between consecutive pillars in the plurality of pillars remains constant in the repeating unit cells and is between 10 μm and 700 μm, the pitch defined as a distance between centers of two consecutive pillars;
- and
- wherein the pillars cover 40-70% of a total area of an abrasive layer of the polishing tool.

A polishing tool comprising:
- a repeated unit of a plurality of teeth forming repeating unit cells, each of the plurality of teeth including a flat top surface with an abrasive material and a side face forming an angle with the flat top surface, the angle being between 75-90 degrees, each and every cell being one of the repeating unit cells;
- wherein each of the plurality of teeth comprises a non-metallic material;
- and
- wherein a pitch between consecutive teeth in the plurality of teeth remains constant in the repeating unit cells and is between 10 μm and 700 μm, the pitch defined as a distance between centers of two consecutive teeth.

A method for operating a polishing tool, comprising:
- applying the same polishing tool for both grinding and buffering operations to a component, thereby providing a smooth and shiny finish on a target surface of a product, wherein edges of a uniformly engraved pattern on a polishing surface is utilized for grinding operation and a flat planar polishing surface provides a desired level of gloss on the surface of the component, the polishing surface comprising circularly positioned pillars forming repeating unit cells, each of the grinding and buffering operations moving the polishing tool in directions including forward/backward, left/right, angles therebetween, and circular rotation;
- wherein each of the circularly positioned pillars includes a top surface with an abrasive material and a side face forming an angle with the top surface, the angle being between 75-90 degrees;
- and
- wherein a pitch between consecutive pillars of the circularly positioned pillars remains constant in the repeating unit cells and is between 10 μm and 700 μm, the pitch defined as a distance between centers of two consecutive pillars.
