2. Chemical-mechanical polishing - Wikipedia

   en.wikipedia.org/wiki/Chemical-mechanical_polishing

   The pad and wafer are pressed together by a dynamic polishing head and held in place by a plastic retaining ring. The dynamic polishing head is rotated with different axes of rotation (i.e., not concentric). This removes material and tends to even out any irregular topography, making the wafer flat or planar. This may be necessary to set up the ...

3. Surface finishing - Wikipedia

   en.wikipedia.org/wiki/Surface_finishing

   A #4 architectural finish is characterized by fine polishing grit lines that are uniform and directional in appearance. It is produced by polishing the metal with a 120–180 grit belt or wheel finish and then softened with an 80–120 grit greaseless compound or a medium non woven abrasive belt or pad. #4 Dairy or sanitary finish

4. Polishing (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Polishing_(metalworking)

   While used less extensively than traditional mechanical polishing, electropolishing is an alternative form of polishing that uses the principles of electrochemistry to remove microscopic layers of metal from a base surface. [3] This method of polishing can be fine-tuned to give a wide range of finishes, from matte to mirror-bright.

5. Polished concrete - Wikipedia

   en.wikipedia.org/wiki/Polished_concrete

   The polishing process begins with a 50-grit diamond resin pad instead of a metal segment. When using the resin pads the steps may be 100, then 200, 400, 800, 1600 and finally 3000+ grit. Throughout the process, a densifier is used to harden the concrete surface, which allows the concrete to be polished.

6. Brasso - Wikipedia

   en.wikipedia.org/wiki/Brasso

   Brasso has also been used to polish out scratches in plastics: It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.

7. Metallography - Wikipedia

   en.wikipedia.org/wiki/Metallography

   Example of a reusable pad for use with diamond suspension. A single magnetic platen is positioned on the grinding and polishing machine to support the preparation pads. The surface of a metallographic specimen is prepared by various methods of grinding, polishing, and etching.
