The hazard of running man over-speed condition northern comes from centrifugal industrial force. tools A result of rotary motion, centrifugal 6in and air-powered force is what causes a weight on the end of dual a string to pull action and disc and sander and model and 1581 and northern the string taught when industrial the weight is swung in a circle. This tools and 6in same force causes air-powered and dual the mass of the grinding wheel to be pulled outward action from the center of rotation as the wheel is spinning. One potential source of serious injury disc in grinding comes from an oversight that is easy to make: operating the wheel in an over-speed condition. While a wheel sander that is run far model and 1581 enough in excess of northern and industrial its rated maximum speed tools may 6in and air-powered and dual shatter within minutes of operation, danger may also result from a action wheel disc run just slightly faster than sander its rated speed. This less model severe over-speed 1581 and northern condition can cause the industrial wheel to be damaged, and tools the damage may 6in result air-powered and dual in breakage after further action use. For disc example, sander and model and 1581 and northern and industrial operating a reinforced, 9-inch tools diameter, Type 27 6in wheel air-powered and dual rated action for a maximum speed disc of sander and model 6,600 rpm on a 7-inch angle 1581 grinder with northern and industrial a speed of 7,700 rpm can cause the wheel to crack. tools and 6in and air-powered and dual and action This disc and sander cracking can lead to breakage later. Any of these actions sets up a disastrous scenario model and 1581 and northern that could lead industrial to an accident involving tools serious injury or 6in and air-powered and dual death. In short, never over-speed a grinding wheel. The speed action and disc of sander the model grinder 1581 must be compared to the northern speed industrial marked tools on the wheel or 6in package to air-powered make sure the machine''s speed is at or dual below action the maximum operating speed disc of the wheel. sander and model Surpassing this rating risks not just 1581 and northern wheel breakage but also the safety of shop personnel. industrial About the author: Roger Cloutier is a senior product tools and 6in safety air-powered and dual engineer action and disc and sander for the Norton Abrasives model and 1581 brand of Saint-Gobain Abrasives in Worcester, Massachusetts. ©2003 www.airsanders.com.
