2. Surface grinding - Wikipedia

   en.wikipedia.org/wiki/Surface_grinding

   Surface grinding. Surface grinding is done on flat surfaces to produce a smooth finish. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth. Sometimes a surface grinder is known as ...

3. Surface finishing - Wikipedia

   en.wikipedia.org/wiki/Surface_finishing

   A drill bit with surface finishing to make the cutting edges harder. Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. [1] Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish ...

4. Pickling (metal) - Wikipedia

   en.wikipedia.org/wiki/Pickling_(metal)

   Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, and rust or scale from ferrous metals, copper, precious metals and aluminum alloys. [1] A solution called pickle liquor, which usually contains acid, is used to remove the surface impurities. It is commonly used to descale or clean steel in ...

5. Stainless steel - Wikipedia

   en.wikipedia.org/wiki/Stainless_steel

   Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an alloy of iron that is resistant to rusting and corrosion. It contains iron with chromium and other elements such as molybdenum, carbon, nickel and nitrogen depending on its specific use and cost. Stainless steel's resistance to corrosion results ...

6. Grinding (abrasive cutting) - Wikipedia

   en.wikipedia.org/wiki/Grinding_(abrasive_cutting)

   The tolerances that are normally achieved with surface grinding are ±2 × 10 −4 inches (5.1 μm) for grinding a flat material and ±3 × 10 −4 inches (7.6 μm) for a parallel surface. [4] The surface grinder is composed of an abrasive wheel, a workholding device known as a chuck, either electromagnetic or vacuum, and a reciprocating table.

7. Tumble finishing - Wikipedia

   en.wikipedia.org/wiki/Tumble_finishing

   Tumble finishing, also known as tumbling or rumbling, [1] is a technique for smoothing and polishing a rough surface on relatively small parts. In the field of metalworking, a similar process called barreling, or barrel finishing, [2] works upon the same principles. Tumbled stones are made with rock tumblers in a process very similar to the ...
