One potential source of serious injury in grinding comes from an oversight that is easy to make: operating the wheel in an over-speed condition. While a wheel that is ingersollrandvacuum-readyrandomorbitalsandermodel4151-5 run far enough in excess of its rated maximum speed may shatter within minutes of operation, danger may ingersollrandvacuum-readyrandomorbitalsandermodel4151-5 also result from a wheel run just slightly faster than its rated 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 ingersollrandvacuum-readyrandomorbitalsandermodel4151-5 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. This cracking can lead to breakage later. Any of these actions sets up a disastrous scenario that could lead to an accident involving serious injury or ingersollrandvacuum-readyrandomorbitalsandermodel4151-5 death.

The hazard of running man over-speed condition comes from centrifugal ingersollrandvacuum-readyrandomorbitalsandermodel4151-5 force. A result of rotary motion, centrifugal force is what causes a weight on the ingersollrandvacuum-readyrandomorbitalsandermodel4151-5 and ingersollrandvacuum-readyrandomorbitalsandermodel4151-5 end of a string to pull the string taught when the weight is swung in a circle. This same force causes the mass of the grinding wheel to be pulled outward from the center of rotation as the wheel is spinning.
