Surface Grinding Formulas


CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.

Surface feet per minute - Wikipedia

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. Its most common use is in the measurement of cutting speed (surface speed) in machining.

Calculation of Grinding Balls Surface Area and Volume

Earlier, we have mentioned one of the grinding media characteristics which is defined by the ratio of the surface area to the volume of the grinding ball (link to the article). As smaller the ratio value,as thinner (the better) grinding process will be. We hope this information will save your time for searching a seemingly simple formula.
