At high speed, CFG is typically performed using plated superabrasive grinding wheels (12,000–24,000 fpm or 60–120 m/sec). This is called HEDG—High Efficiency Deep Grinding. Today, wheels may also be made with vitrified superabrasive segments bonded to the periphery of a metal core.

Once captured, general practice recommends a minimum duct transport velocity of 1066 m/min / 3500 fpm (but 1219 m/min / 4000 fpm to 1524 m/min / 5000 fpm is often necessary). A hood that encloses as much of …
Look at the rpm of the drive wheel. Using a 4" drive wheel your belt speed will be slightly above the rpm of drive wheel. i.e. - 1800 rpm motor with 4" drive wheel will have around a 1900 SFPM belt speed. The larger the drive wheel, the faster the belt speed at same rpm. Click to expand... 4 4trout Joined Jul 3, 2014 Messages 25 Jan 20, 2018 #5

Surface feet per minute (SFPM or SFM) is the combination of a physical quantity (surface speed) and an imperial and American customary unit (feet per minute or FPM). It is defined as the number of linear feet that a location on a rotating component travels in one minute. What is Inches per minute (IPM)?
