Grinding Wheel Safety: Respect The Maximum Speed | …

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. This represents an over-speed of about 1.5 times the wheel's designed speed.

Is there ever a need to use different spindle RPM on a ...

8356. You can use RPM to make a wheel work harder or softer. High speed is harder, holds a corner longer. Or you can use different grade wheels to do the same thing. Wheel grades are a unit grain loading grit/bond breaking force messy thing that only grinding nuts get into. You can also change dressing speeds to sort of do the same thing.

Old stone grinding wheel Safety - Grinders, Sanders, etc ...

I have to say NEVER power up a stone intended for hand use. the maths is rather complicated for me, but maximum rpm anything should spin at has alot to do with ft/min or surface speed. An increase of an inch in diameter has big changes on centrifugial forces! If a grinding stone has no 'safe rpm' label best to use it by hand only.

RPM & SFPM Defined | Mach-B Grinding Wheel Shaping & Resizing

In the world of grinding, there are two measures for speed that you need to know and understand how they affect one another. RPM and SFPM. RPM = Revolutions Per Minute; defined as the number of complete axis turns per minute. SFPM = Surface Feet Per Minute; defined as the distance any one abrasive grain on the cutting surface travels per minute.
