The condition of the material at hand determines what type of abrasive will be applied. The first stage, if the material is unfinished, starts with a rough abrasive (perhaps 60 or 80 grit) and each subsequent stage uses a finer abrasive, such as 120, 180, 220/240, 320, 400 and higher grit abrasives, until the desired finish is achieved.

While nearly any metal may be electropolished, the most-commonly polished metals are 300- and 400-series stainless steel, aluminum, copper, titanium, and nickel- and copper-alloys. Ultra-high vacuum (UHV) components are typically electropolished in order to have a smoother surface for improved vacuum pressures, out-gassing rates, and pumping speed.
Struers provide cutting, mounting, grinding, polishing, microevaluation, hardness testing equipment [6] and consumables [4] for the analysis of metal samples. Government departments, [ 7 ] universities, [ 8 ] NASA [ 9 ] and the International Metallographic Society use Struers equipment in the analysis metal or material samples.
Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...
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.
The city is home to a number of large estates, including Gore Place, a mansion built in 1806 for former Massachusetts governor Christopher Gore, the Robert Treat Paine Estate, a residence designed by architect Henry Hobson Richardson and landscape architect Frederick Law Olmsted for philanthropist Robert Treat Paine, Jr. (1810–1905), and the ...
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.
