In short, mini never over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked random and orbital on the wheel or package to make sure the machine''s speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel. About the air author: Roger Cloutier sander is a senior product safety engineer for the Norton Abrasives brand of Saint-Gobain Abrasives in Worcester, Massachusetts.

One mini and random potential source of serious injury in grinding comes from an orbital oversight air and sander and mini that is easy to make: operating random and orbital the wheel in an over-speed condition. While air a wheel sander that is run far enough in excess of its rated maximum speed mini and random may shatter orbital within minutes air of sander and mini operation, danger may also result from a wheel run just slightly faster than its rated speed. This less severe over-speed condition can cause random the wheel to be damaged, and the damage may result in breakage orbital after further use. air For example, operating sander a reinforced, 9-inch diameter, Type 27 wheel rated for a mini maximum speed of 6,600 rpm on a 7-inch random angle orbital and air and sander grinder with a speed of 7,700 rpm can cause the wheel to crack. This cracking can lead to breakage mini and random and orbital later. Any of air these actions sets up a disastrous scenario that could lead to an accident involving serious sander injury or death.
