Emery wheel edit
Is "emery wheel" equivalent to "grinding wheel"? -- Kjkolb 08:43, 11 November 2005 (UTC)
It was right end of the 19th century and beginning of the 20th when "emery" was the most used abrasive grain.
Since then much more efficient man made abrasives: Aluminum oxides "Corundum", silicon carbides "Carborundum", diamonds, cubic boron nitrides (CBN)...are used to make grinding wheels and emery is no longer used for this application.
Natural emery is not very hard and may contain a significant quantity of hazardous free silica that's why it is no longer used for grinding wheels and even for "emery cloth" now made with aluminum oxide or silicon carbide grains as well as "sand paper".
Still many people continue to use the term "emery wheel". Junglejob 11:24, 5 December 2006 (UTC)
Emery cloth is used in the industry to vaguely differentiate specialized paper/belt grinding media and sandpaper. Emery wheel, however, is no longer used. - Toastydeath 23:20, 5 December 2006 (UTC)
Tapered Wheel edit
What is this "...and are used in situations where the wheel may catch on the work surface and fail to prepare and you prepare to fail." supposed to mean? I understand the principles of both the cliche, and the tapered wheel, but why is it stated this way in this section? 75.167.140.82 20:23, 19 May 2007 (UTC)
- Very good question. The whole part you quote can go, as the shape of the grinding wheel has nothing to do with if it will catch on the part or not. - Toastydeath 23:38, 19 May 2007 (UTC)
Functions edit
The following items aren't functions of the wheel. What should they be categorized as? Wilhkar (talk) 21:02, 22 February 2010 (UTC)wilhkar
Poor Reference edit
I was hoping to reference grinding wheels, but I find that the information in this page is not sufficient. For example what does WA54 JVI STK2971 mean? As far as I know WA is White Aluminum Oxide. There are other types of aluminum oxide also like 32A, the ALOX section should be expanded, and hopefully some more intelligent people can provide more details on what these other numbers and letters mean, and how to decode them.104.128.105.162 (talk) 22:43, 10 December 2016 (UTC)
