The media cuts aluminium (aluminum in US spelling) — and when a buyer searches compounds for aluminum, that is the same product. The compound decides whether the cut leaves a surface you can sell. That split is the whole subject of this page, because aluminium is the metal where the chemical half of the process […]

A motorized barrel — often searched as motorized barrell with a double L, and both spellings turn up in searches — is a rotary finishing barrel with its own drive instead of a hand crank or a belt off another machine. The name sounds like a detail. It is not: on a production barrel, the […]

Abrasive media — and the plural forms abrasive materials and abrasive material, which buyers use interchangeably — is sold by name — ceramic, plastic, glass bead, aluminium oxide, garnet — and those names are the least useful thing about it. Two charges both sold as ceramic media can differ by a factor in how fast […]

Surface technology is an enormous subject, and that is exactly the problem with buying it. The literature covers electroplating, anodising, conversion coatings, thermal spray, vapour deposition, mechanical finishing, laser texturing and more, and each family has a textbook. A buyer with a part on the bench does not need the textbook. They need to know […]

Polishing jewelry at a bench is a wheel, a mop and a hand. As a production step it is a different problem, and it is not a shine problem — it is a metal-loss problem. On a silver or gold part the material removed by polishing is the most expensive material in the building, and […]

A compound for silver is not a milder steel compound. Silver fails in ways steel does not: it tarnishes chemically rather than corroding electrochemically, it is soft enough that the compound’s aggressiveness is a money decision, and its most common alloy — sterling, 925 parts silver to 75 copper — has a second phase that […]

In the trade, “polishing” and “buffing” are used as if they were two words for one thing, or as if buffing were simply the shinier second half of polishing. Both readings cause expensive mistakes, because the two operations differ in the one property that decides everything downstream: whether material and geometry are being removed. Polishing […]

Most people who search for a stainless steel buffing compound have a picture in their head of a solid bar of wax or paste, rubbed onto a rotating cloth wheel, bringing a stainless part up to a mirror. That picture is accurate for one route — and it is the wrong product for the route […]

The phrase in the search box covers two different things, and the two get mixed up constantly — so settle it before anything else: Ceramic polishing wheels — the tool. A ceramic-bonded abrasive wheel: abrasive grain held in a vitrified (ceramic) bond, mounted on a spindle, dressed as it wears. It is a consumable, and […]
