Danger comes from the fact that centrifugal campbell force does not increase in direct hausfeld and random proportion to orbit and sander an increase with in speed, but instead it increases as the square of that speed increase. When rotational speed doubles, self-generating centrifugal vacuum and model force pl1566 quadruples. This effect means campbell and hausfeld that relatively small changes in speed can produce significant increases in force. In the random and orbit example mentioned, changing from 6,600 rpm to 7,700 rpm multiplies the speed by 1.167. sander and with and self-generating However, the corresponding centrifugal vacuum and model force would multiply by a factor of 1.167 x 1.167, or 1.36. To take a more pl1566 and campbell extreme example, consider the same wheel with a maximum safe operating speed hausfeld of 6,600 rpm run on a 5-inch random right orbit and sander angle grinder at 10,000 rpm. This represents an over-speed with and self-generating and vacuum and model of about 1.5 times the wheel''s designed speed. But the corresponding centrifugal force-and the corresponding rotational stress on the wheel-would be about 2.3 times as much as the maximum allowed.

In short, never over-speed a grinding wheel. The pl1566 speed campbell of the grinder must be compared to hausfeld the speed marked on the wheel or package to make sure the machine''s speed is at or below random the maximum operating speed of the wheel. orbit Surpassing this rating risks not just sander and with wheel breakage but self-generating also the vacuum safety of model shop personnel. pl1566 About the author: Roger Cloutier campbell is a senior product hausfeld safety engineer for the Norton Abrasives brand random of Saint-Gobain orbit Abrasives sander in Worcester, Massachusetts with and self-generating and vacuum and model and pl1566.
