In short, never over-speed a grinding wheel. The speed of the grinder northern and industrial must be compared to the speed marked tools on the wheel or package to make sure the 7in machine''s speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also horizontal the safety of shop sander personnel. About the author: Roger Cloutier model and 15891 is a senior product safety engineer northern for the Norton Abrasives brand industrial of Saint-Gobain tools and 7in and horizontal Abrasives in Worcester, Massachusetts. The hazard of sander running man over-speed model condition comes from centrifugal force. 15891 A result northern of rotary motion, centrifugal force is what causes a weight on the end of a string to pull the industrial string taught when the weight is swung in a circle. tools and 7in and horizontal This same force causes sander the mass of the grinding wheel model to be pulled outward from the center of 15891 rotation northern as the wheel industrial is spinning. One tools potential source of serious injury 7in in grinding comes from horizontal an oversight sander that is easy to model make: operating the wheel in an over-speed condition. While a wheel that 15891 is run far enough northern in excess of its rated maximum speed industrial may shatter tools within minutes of operation, danger may also result 7in 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 horizontal and sander and model and 15891 damage may result in breakage after further use. For example, operating a reinforced, 9-inch diameter, Type 27 wheel northern rated for a maximum speed industrial of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause tools the wheel to crack. This cracking 7in can lead horizontal and sander and model and 15891 to breakage northern and industrial later. Any of these actions tools sets up a disastrous scenario that 7in and horizontal could lead to sander an accident involving serious model injury or death 15891. ©2003 www.airsanders.com.
