  • Grinding Wheel Safety: Respect The Maximum Speed : Modern

    Mar 15, 2003· In the example mentioned, changing from 6,600 rpm to 7,700 rpm multiplies the speed by 1.167. However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. To take a more extreme example, consider the same wheel with a maximum safe operating speed of 6,600 rpm run on a 5-inch right angle grinder at 10,000 rpm.
