For example, operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel to crack.

Always check to make sure the spindle speed of the grinder does not exceed the maximum safe speed of the grinding wheel. Its RPM that gives you the ccorrect peripheral speed. Use the following formula to determine the grinding wheel speed (rpm): RPM  =           3.82 x sfm                   However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. Because of the maximum safe wheel speed of most vitrified grinding wheels and maximum spindle speeds, most tool post grinding is done around 6,500 sfm.

grinder rpm and wheel rpm

it’s the first time i see granulometric curves explained. Selecting a finer grind setting also results in a smaller median grind size and more fines. For example, operating a reinforced, 9-inch diameter, Type 27 wheel rated for a maximum speed of 6,600 rpm on a 7-inch angle grinder with a speed of 7,700 rpm can cause the wheel to crack. This increases the cutting force per grain, causing the wheel to act “softer”. Signup is risk-free and you can cancel your subscription at any time during the trial period! Source: Blackwater Issue.
