2. Polishing (metalworking) - Wikipedia

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

   In metallography and metallurgy, polishing is used to create a flat, defect-free surface for examination of a metal's microstructure under a microscope. Silicon-based polishing pads or a diamond solution can be used in the polishing process. Polishing stainless steel can also increase its sanitary benefits.

3. Floor scrubber - Wikipedia

   en.wikipedia.org/wiki/Floor_scrubber

   Floor buffers or rotary floor machines use rotary brushes of a soft material to clean, scrub, and polish linoleum surfaces. For marble and wood floors, floor polishers may be used to apply protective coating to the floor. [1] Floor burnisher is the term for a high speed floor buffer that rotates its pad at over 1000 RPM.

4. 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 ...

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. 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.

7. 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
