Grinding Wheel Safety Respect The Maximum Speed . this less severe over-speed condition can cause the wheel to be damaged, and the damage may result in breakage after further use. for example, operating a reinforced, 9-inch diameter, type 27 wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel to crack.
Grinding Wheels Speed Limit Breaking The Law abrasive wheels shall be used only on machines provided with safety guards as for cutting-off wheels 16 inches diameter and smaller and where speed does not and the use of side pressure in wheel operation limits the use to reinforced failure to observe these rules might cause excessive flange pressure around
Mar 15, 2003 This represents an over-speed of about 1.5 times the wheels designed speed. But the corresponding centrifugal forceand the corresponding rotational stress on the wheelwould be about 2.3 times as much as the maximum allowed. In short, never over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked on the ...

It is important that wheel speeds never exceed the safe limit of the grinding wheel desgn. Centrifgal forces within a spinning wheel can cause it to break apart at speeds above its design limit. Each wheel is speed tested and marked with speed limits before it is sold. For safe handling of grinding wheels see ANSI B7.1 standards.
Dec 15, 2000 Dec 15, 2000 Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute. Working at higher speeds usually requires specially designed wheels for high speed grinding.
Nov 28, 2016 Nov 28, 2016 Christian B. on November 28, 2016. A loud scraping and grinding noise coming from the front right of the car. It only occurs at low speeds, 10-15mph, but not at speeds higher than that. The car drives normally at normal speeds, but it sounds shocking at low speeds. There is nothing hanging below the car, and the tyres are fully inflated.
